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