I was able to (through heavy Claude use) successfully reverse engineer a golf cart motor controller that is programmable over USB, but only was supported by a Windows application. Claude walked me through using ILSpy on the .NET assembly, using Wireshark to capture the protocol over USB, and to completely map out all of the functionality in the Windows application. The output was a portable C library and CLI program which, so far, has worked well.
I consider myself kind of an AI detractor but even I'll admit that the tool allowed me to do something it would have taken weeks-to-months to learn to do the hard way.

Had a similar experience getting a niche app running under wine. The bot had to bring in a different open source renderer, patch dlls, adapt a mapping tool from a different chip architecture to partly map and modify the binary, crazy stuff. Alternatives exist but are expensive, this got it working in an hour when doing it myself would probably be 2 weeks.

Last week I had Claude add support for aac audio to davinci resolve on Linux, just by patching the binary. It did almost exclusively with gdb and objdump, patching about 5 functions over an hour or two.
I only got it to the proof of concept stage. The patch adds aac but breaks flac support in the process. And it only works for aac in mp4 container files. But I’m sure with a bit of time we could make a patch which works everywhere and is additive only.
I say ‘we’ - I barely helped. Almost all the work was done by Claude.
Here’s Claude’s report, if anyone wants to build on this work:
And with the Linux Kernel being friendly to both LLM usage and a modern language, for some of us who don't know C, a huge barrier is lifted from being able to write device drivers.
Not a successful anecdote, but I have a Windows Hello compatible Kengsington fingerprint reader, and for some time I wanted to write drivers for Linux. Even without using C, it would have been a huge undertaking only to fail in the end; because Claude did much of the research and concluded that the device wouldn't work on Linux (can't remember why but it made sense). Then it suggested what could work.

Back in the day when dial-up modems were a "significant" market, the concept of "WinModems" came around. Minimum hardware, maximum software. If the sensor is good enough to actually work though, it probably won't be long before an agent can implement the driver, if it can't already.

LLMs are good at producing what they/the public know.
In this case:
LLMs know the USB Spec very well.
LLMs know how to read raw packet dumps.
LLMs know how to convert a packet dump to USB spec
LLMs know how to write code to generate USB packets from the spec.
LLMs are also VERY good at transliteration, i.e., converting known-good Python to Rust.
Basically, If you have a well-documented problem, the LLM is a shortcut to learning it yourself. LLMs fail when you have a novel or poorly documented problem. They also fail when you provide the LLM with terrible context or too much context.

This is a very novel, reasonably-poorly-documented problem, and so far it has batted 1.000.

I had a discussion about this with a friend recently. I was using an LLM with a serial console that it wrote to allow us to share a connection to a Z80 computer running CP/M. I was having trouble with the assembler, it wouldn’t assemble in user 1 of a particular disk, so I asked the LLM for help. It debugged ASM.COM and the BDOS, walked through the source compared to memory dumps, basically banging its head on the wall for an hour or more, until it finally figured out and verified that my disk had a bad block. I never would have put in that much effort to find the root cause of the problem.

It's LLMs' generalist skills. I think reverse engineering is usually hard when you're in an unfamiliar domain. Eg I've never programmed a videogame or windows application but I'm trying to crack one. On the other hand if you know the domain, and know what the programmers' intentions must be in any given block of code, it's often straightforward. There are no unfamiliar domains for LLMs, including it seems proprietary software.

Unfortunately this is a very misleading article and headline. I don't doubt the end result - it's useful that it works, but it's not "natively" and, unlike what some people assume, Claude didn't write a driver. It basically used HP's existing proprietary driver in a Linux VM on macOS, and just bridged that to macOS.
It also requires a root launcher that runs code from the user ~/.hp1008 dir, so security is weakened.

UPDATE: Noted, shifted to a 100% native MacOS version now :D
"Also some clarification on the "he's just using the linux driver in the VM" - not quite
This is one of the weirdest batch of printers HP made because it's a rebranded Samsung - it "comes" under HP's unified drivers system but specifically has Samsung's printer language so compatibility is extremely messy.
What this version does is take the Linux Unified Driver and extract just the relevant component, rastertospl, basically the codec that turns CUPS raster data into the Samsung SPL format the printer understands. That codec is then wired into macOS’s native CUPS stack, so printing happens through the system like a normal driver. There’s no Linux VM handling the actual print workflow and the entire process basically acting as a driver normally at system level.
In theory, yeah - rastertospl could be reimplemented from scratch. But that would be way more unreliable while turning this from a ~4-hour project into a ~4-day reverse-engineering project, when starting this, I really just wanted a working home printer and running a tiny compatibility applet in Docker just for that codec feels like a pretty reasonable compromise AND I get to not see my mac kernel crash if it messes up.
I didn't expect this to blow up this much lol, so I'll be experimenting with this further and am already in talks with the splix team to sort this specific version out"

On a similar experience, I use moonlight on my Android TV to stream video games from my computer in another room. I use my own fork from an unmerged PR which enables me to use an Xbox One Wireless adapter so I can play with my pad wirelessly. These pads have a 3.5mm jack on them which on Windows and Linux enables me to route audio from the game to headphones connected to the pad. Moonlight and the xow driver it bundled, was nowhere near being able to provide this as a feature.
After about 5 hours, feeding it the GIP spec, an export of sniffed usb traffic from Windows, prior art (xone driver for linux), and giving Claude connectivity to my Shield via adb, I had it working. This continuously blows my mind that I dont have to beg a developer on Github to do it for me.

I have another controller-related anecdote.
I have a Razer Wolverine Xbox controller that has extra back paddle buttons. The controller doesn't expose the paddles directly to PC's over USB. You have to use button remapping on the controller to map them to 'real' Xbox buttons for the PC to see them. But I wanted to use the back paddle buttons on Steam as separate controls.
So I downloaded the latest firmware update off the internet (because what device doesn't have firmware updates these days), installed Ghidra and an MCP server for it, and told Sol to look for how I can expose these extra buttons to a PC host. Maybe we could write a firmware patch?
Turns out the controller already has a special mode to expose those buttons, possibly as a hardware test. But it was enough to write a Linux driver to put the controller into that mode, and a little bit of extra driver code to map the paddles to a Linux controller button, and voila. Paddles working in Steam.
And it only took a few hours to do, too. I spent more time making an open source repository out of the concept than I spent making it work.

I can work around it by each time I boot, I press the button to go to max volume, then lower the volume in Linux to the desired level but it's been an annoyance. I described the issue to codex and within a few minutes it had it fixed by updating the pipewire device profiles to use the volume control it exposes.

Along similar lines I used Codex to reverse engineer and build a modern driver for the niche, proprietary Sony USB protocol for an old camcorder I have lying around, having never done anything like that or used Rust before. It feels like LLMs could be a huge force in making older hardware usable again.
Recently, I had bizarre situation: I wanted to play a game from my childhood on Windows 11, but, without changing two booleans in the settings, I could not reliably move my in-game cursor. The catch is that to change those values in the settings, I needed to move my in-game cursor. So I was stuck.
After digging around, I found a file that looked like it could be the settings file, but it was not plaintext.
Naturally, I told Claude all the options I knew existed in the settings and told it what I needed it to change.
After about 10 minutes poking around my system and the file, it correctly identified the bits (not bytes!) that corresponded to the two settings, and flipped them on. It. Just. Worked!
(Well, then I found out I actually needed to do quite a lot more than flipping those bits, but I still found it worth sharing).
I have many more experiences similar to these. LLMs are an amazing superpower.

I've said this time and time again but with LLMs I got the joy of being a little kid learning to code and build stuff again. I haven't had such a custom-built setup since my earliest college days, because I had lost the time to tinker and looked for stuff that just worked. Now tinkering is so much easier that I mod the software I use all the time as well.
For example, I needed to change something in a particular function of firefox (which was in and of itself an amazing claude adventure to find that solved a problem I've had for well over 2 years), but only that very specific function.
I didn't want to fork firefox and have to constantly rebuild it just because of this one function. So I setup an LD_PRELOAD (well, not LD_PRELOAD, but the macOS equivalent) trick that injects only my modified function, as well as a full mechanism that traps firefox's auto-update process to reinject/re-arm the LD_PRELOAD trick into newer versions. I've had it going on for 3 months without any issues.
I counted and I have about 18 custom built apps ranging from "full blown swift GUI" to "tiny helper script" that have really changed how I interact with my computers for the better. It's so cool to be living this revolution.

I usually answer saying there's not really a hack for it, you just work with it, convey thoughts decently and try out things with educated guesses until it sticks with these projects.
my Brother dcp-t230 also doesn't have macos drivers and it's a usb only printer.

It didn't write a driver. It used a linux driver. You don't need an LLM.
Had a similar experience. I bought an ePaper display and a Pi 4 to run a calendar widget on. I got stuck because the open source project I was building off expected the previous generation of ePaper display, and the firmware had changed completely. I found the new firmware examples, but got stuck trying to get it to work. With Claude assisting we banged it out in two sessions of about 3 hours each.

Nice! About a year ago I used Claude to make a macOS driver for an ancient laser engraver that only ever worked with Windows.
I tried to get Copilot to port the Linux drivers for my HP CP1025 to macOS, but it failed. Even modern Linux can’t print to it any more, I had to put an older distribution on a RasPi and now I’m printing at reduced quality.
It was crazy how the LLM held on to outdated information. It suggested so many things that might have worked on an older macOS but very obviously wouldn’t nowadays. It also tried to port from Linux for a while until it eventually discovered that cups on Linux didn’t support that printer either.

I've seen this explained as LLMs being well - language models. Driver binaries are just a language understood by the machine executing the binary. While its basically unreadable for normal humans, it is just another language for LLMs & they are able to operate on it, changing the result & translating it (e.g. correlating with specs, logs, docs, etc.).
Given the positive results from what I've heard, this might be actually one are where LLMs could prove useful for once.

If this could all finally solve, once and for all, printing and scanning issues it'd be lovely (btw there are entire businesses who's only raison d'etre is "installing printers at clients and fixing them when they stop printing").
But of course it's hard not to both marvel and lament (at) the fact that in the mid-1990s (so yup 30 years ago) I could:
nc 192.168.1.150 9100 < tiger.ps
And the native PostScript printer (also an HP laser btw: a LaserJet) would just start printing.
I know, I know, about garbled print jobs, pages of codes being printed, etc.
But still: it's hard to not at least wonder if some things haven't been lost. For a start printers with their own IP addresses were sweet (instead of a USB cable and, now, people setting up, say, a Pi just to expose a LAN IP for/to their printer). Then of course another talk could be had about the "quality" of modern day HP laser printers compared to what you'd get int the nineties.

I've always thought USB-only made no sense on a printer. If there was one device in your house that multiple computers (and phones, don't forget) would want to use simultaneously, it's a printer. I'll only buy a printer that has its own built in network connectivity. Infuriating to have to stick a Pi onto your printer just so it can do what should be basic, table-stakes functionality.

Personally, "AI wrote a driver" and "AI rebottled an existing solution and sold it as Dr. Claude's Miracle Driver" are semantically very different claims to be making in the public square.

Cool nonetheless.
kotaKat 23 hours ago [-]
sliiiiightly obscure in that it seems to use the ULD drivers (or a variant of); HP's "unified linux driver" that talks Samsung's printing language. it's weird.
I consider myself kind of an AI detractor but even I'll admit that the tool allowed me to do something it would have taken weeks-to-months to learn to do the hard way.
I only got it to the proof of concept stage. The patch adds aac but breaks flac support in the process. And it only works for aac in mp4 container files. But I’m sure with a bit of time we could make a patch which works everywhere and is additive only.
I say ‘we’ - I barely helped. Almost all the work was done by Claude.
Here’s Claude’s report, if anyone wants to build on this work:
https://claude.ai/code/artifact/87d38c2e-9ecb-4066-90cf-e0b2...
>Additional Old Linux Drivers Face Removal Due To Noise From AI/LLM Coding Agents
https://www.phoronix.com/news/Linux-Retiring-Moxa-Driver
Not a successful anecdote, but I have a Windows Hello compatible Kengsington fingerprint reader, and for some time I wanted to write drivers for Linux. Even without using C, it would have been a huge undertaking only to fail in the end; because Claude did much of the research and concluded that the device wouldn't work on Linux (can't remember why but it made sense). Then it suggested what could work.
In this case:
LLMs are also VERY good at transliteration, i.e., converting known-good Python to Rust.Basically, If you have a well-documented problem, the LLM is a shortcut to learning it yourself. LLMs fail when you have a novel or poorly documented problem. They also fail when you provide the LLM with terrible context or too much context.
This is a very novel, reasonably-poorly-documented problem, and so far it has batted 1.000.
After 5-6 consecutive approaches fail, I need a reason to think the next one might work out to stay motivated.
Claude will keep burning credits trying new approaches until something sticks. That's a huge advantage in a field where most of the things you try don't go anywhere.
Reverse engineering isn't so much hard as it is exhausting.
LLMs simply don't care about exhaustion.
It also has the benefit that it doesn't usually matter too much if it gets minor details wrong. It's definitely one of the areas - like hacking - where it's a) tedious and b) insensitive to mistakes where AI absolutely shines.
The whole thing took about a day, spread out over a week or so. Without AI, I wouldn't have even started the project, because I couldn't spare the time it would have taken.
None of this would have been possible (or at least practical from a time-value perspective) for me to do without Claude driving the whole exercise.
The odds of success go up a LOT when the stock firmware is easy to extract and reverse engineer.
Or are we in a really cool time where we've solved everything so much so many times we can focus on other things?
Tertiary question: If answer two, what the fuck is that?
For programmers this is the equivalent of when accountants got spreadsheets. We can just tell the machine what to do without manually performing all the steps.
Some programmers enjoyed the code writing more than the problem solving though.
It also requires a root launcher that runs code from the user ~/.hp1008 dir, so security is weakened.
https://github.com/Kuberwastaken/hp-laser-1008a-macos
Previous context I shared on X:
"Also some clarification on the "he's just using the linux driver in the VM" - not quite
This is one of the weirdest batch of printers HP made because it's a rebranded Samsung - it "comes" under HP's unified drivers system but specifically has Samsung's printer language so compatibility is extremely messy.
What this version does is take the Linux Unified Driver and extract just the relevant component, rastertospl, basically the codec that turns CUPS raster data into the Samsung SPL format the printer understands. That codec is then wired into macOS’s native CUPS stack, so printing happens through the system like a normal driver. There’s no Linux VM handling the actual print workflow and the entire process basically acting as a driver normally at system level.
In theory, yeah - rastertospl could be reimplemented from scratch. But that would be way more unreliable while turning this from a ~4-hour project into a ~4-day reverse-engineering project, when starting this, I really just wanted a working home printer and running a tiny compatibility applet in Docker just for that codec feels like a pretty reasonable compromise AND I get to not see my mac kernel crash if it messes up.
I didn't expect this to blow up this much lol, so I'll be experimenting with this further and am already in talks with the splix team to sort this specific version out"
The "only built for Windows" is also a little dubious. Technically I suppose HP could have just intended it as a Windows printer, but the driver clearly already exists in CUPS, which Apple also uses, so porting the driver isn't an unreasonable thought.
OP should probably add this to his list of accomplishments on LinkedIn...
I bought some cheap host-managed SATA drives the other day that the BIOS can't see and Windows won't recognize. I asked Claude to write a Windows app so I can use them, and it resisted at first, but then gave up and wrote it and they now work great.
It had to implement the entire stack of bare-metal drive functions over SATA and a whole new filesystem to go with it.
I am sooo tired of this AI generated slop.
Apart from occasional hallucinations we celebrate their ability to dissect information and to find obscure links between facts. Hence their stunning effectiveness in finding security holes or new approaches to math problems.
Interestingly the generative part - producing the answers - is what we are criticizing a lot: we think the code is verbose, texts have a weird repetitiveness to them etc.
After about 5 hours, feeding it the GIP spec, an export of sniffed usb traffic from Windows, prior art (xone driver for linux), and giving Claude connectivity to my Shield via adb, I had it working. This continuously blows my mind that I dont have to beg a developer on Github to do it for me.
Claude could do it for me for $20.
I have a Razer Wolverine Xbox controller that has extra back paddle buttons. The controller doesn't expose the paddles directly to PC's over USB. You have to use button remapping on the controller to map them to 'real' Xbox buttons for the PC to see them. But I wanted to use the back paddle buttons on Steam as separate controls.
So I downloaded the latest firmware update off the internet (because what device doesn't have firmware updates these days), installed Ghidra and an MCP server for it, and told Sol to look for how I can expose these extra buttons to a PC host. Maybe we could write a firmware patch?
Turns out the controller already has a special mode to expose those buttons, possibly as a hardware test. But it was enough to write a Linux driver to put the controller into that mode, and a little bit of extra driver code to map the paddles to a Linux controller button, and voila. Paddles working in Steam.
And it only took a few hours to do, too. I spent more time making an open source repository out of the concept than I spent making it work.
The "linux" support is pretty narrow (because I made this for myself). It's restricted to SteamOS. But I'm sure it could be ported easily, the repository contains documentation about the important parts from reverse engineering the firmware.
I used to feel proud of the fact I reverse engineered some of my laptop's features using stuff just like this. I suppose that's over.
I don't expect Claude and other hosted AI's to be available so freely and thats when it'll get harder for me to do stuff like that.
There's even a zero-install method via https://printervention.app where it runs that Linux VM isolated inside a WebUSB-capable browser. That website itself was posted right here on HN not too long ago.
I get that the LLM code assistant software prefers writing stuff, but constantly re-writing the same solution seems a bit inefficient.
LLMs can do stuff but this isn't a good example.
> Thanks for being such a game debugging partner through all the test pages. Enjoy printing, you and the family.
Maybe it's because my own LLM usage is very "Question > Answer" or "Do this > Agent does that" and I never say "Wow, that's crazy it works, thank you!" at the end or such, so I don't see that sort of things, but if I saw that regularly I'd turn me off so badly from using LLMs. I'm not exactly sure where this feeling is coming from though, it's relatively innocent but just feels so inauthentic, I'm guessing because it's simply a machine.
So I find it common (and fine, I suppose) for Claude to reply using that context. "Let me know what your wife thinks of the app" etc.
Seems an oddly specific thing to hone in on otherwise.
https://github.com/alexnorton/handycam-rs
After digging around, I found a file that looked like it could be the settings file, but it was not plaintext.
Naturally, I told Claude all the options I knew existed in the settings and told it what I needed it to change.
After about 10 minutes poking around my system and the file, it correctly identified the bits (not bytes!) that corresponded to the two settings, and flipped them on. It. Just. Worked!
(Well, then I found out I actually needed to do quite a lot more than flipping those bits, but I still found it worth sharing).
I have many more experiences similar to these. LLMs are an amazing superpower.
For example, I needed to change something in a particular function of firefox (which was in and of itself an amazing claude adventure to find that solved a problem I've had for well over 2 years), but only that very specific function.
I didn't want to fork firefox and have to constantly rebuild it just because of this one function. So I setup an LD_PRELOAD (well, not LD_PRELOAD, but the macOS equivalent) trick that injects only my modified function, as well as a full mechanism that traps firefox's auto-update process to reinject/re-arm the LD_PRELOAD trick into newer versions. I've had it going on for 3 months without any issues.
I counted and I have about 18 custom built apps ranging from "full blown swift GUI" to "tiny helper script" that have really changed how I interact with my computers for the better. It's so cool to be living this revolution.
Unfortunately, as I look around, I see most of the hardware vendors around me as gatekeepers. They prevent me from writing custom code in various ways. Apple restricts access to NFC or their UWB positioning, Supernote Manta does not let me access a bluetooth microphone, the list goes on. Denon at least has an API in their amps/receivers: buggy, but it's there.
I unfortunately can't see it becoming in any way legally mandated either, just have to hope for a good vendor.
Makes it so if there’s an issue I don’t get a kernel panic
Maybe it could write something CUPS compliant though ?
