A kernel driver for legacy Wacom serial tablets
Having gotten back to doing some art on computer, I decided to dust off my old Wacom Digitizer II again. It’s always a bit of an adventure trying to get it to work on a new system, as some configuration system has always completely changed since the last time I hooked it up. However, this time, I discovered that while the general approach to detecting and configuring input devices had improved a lot, support for these old serial Wacom tablets had been completely removed from the xorg Wacom input driver!
Initially I was pretty irritated, as you can imagine, but after looking at the code that had been excised, it was clear that this was for the best. Given the new(ish) approach to handling input devices in the Linux kernel, having all the support for the device on the X side is now clearly the Wrong Thing. So, I set about reading as much code as possible related to serial Wacom tablets, and writing a serio-based driver.
