I read this on hacker news awhile back, and enjoyed it quite a bit. The unrelated trivia part about USB keyboards needing at least 103 keys or they're just a keypad especially stuck with me, and has been cited in discussions of a certain meme:

This is great and I appreciate it being posted.

I really want to figure out how to get into at least some linux development, purely for my own greedy purposes of wanting to have a working machine.

This is a delightful article. Parts of it had me giggling to myself, and I honestly learned more about some linux basics than I expected.

Trivial! The tricky part is to make this driver to work correctly :)

Found this to be an interesting read, and well written. Thanks for sharing it.

Trivia you can use to woo potential partners Here’s 443 pages on generic HID implementations.

My pants!

Great read, with some amusing asides.

Shots fired!

This is amazing. I love discovering new/interesting developer blogs like this one, which is a challenge considering they’re all buried by SEO bullshit.

This is a great write up, not only in content, but also in spirit and tone. An enjoyable read beginning to end and inspires me to try more stuff.

Shit... kind of makes me want to learn Rust now!

Anyway, wonderful write up. No BS, both shortcuts if you just want to the code and in depth links e.g. https://www.beyondlogic.org/usbnutshell/usb1.shtml all written with a fun tone. Plenty of actually useful content showing us all that sure, it is not trivial to write a (USB) driver but it is also probably not as hard as we imagine. Particularly enjoyed the :

• userspace driver, namely being able to tinker locally without feel the pressure to push back the work to Linux the kernel itself
• libusb and other drivers, namely that there is a myriad of points to start from already, not just writing reverse engineering bits in memory to the new device and hoping it'll work

As I was doing that, I also thought I’d message the vendor and ask them if they could share any specifications or docs regarding their protocol. To my surprise, Nanoleaf tech support responded to me within 4 hours, with a full description of the protocol that’s used both by the Desk Dock as well as their RGB strips.

Now that is cool.

Neat. I have a wireless usb headset(Lucidsound ls50x) that I'm trying to do the same for but have zero Linux experience. This is a good read for me. Thanks for sharing!

Very enjoyable writing style

This gives me hope.

Very cool! Added the RSS.

Great writeup, great read!

Thanks for sharing.

Nice. Now what do I do if I have ~0 device driver experience^[not fully 0, because I might have used setpci a few times and built some drivers from source]?
Oh and I also have 0 devices to make a driver for :P, so need to fix that too.

The author not only uses ASCII bricks ( ▓ ) as bullets, and not only uses silly CSS tricks to mark down animated rainbow text rather than using the four megabyte or whatever jquery library which would inevitably tempt everyone else, but also goes as far as to literally name the aforementioned CSS class "funky."

I think I like this cat already.
