Kinesis Freestyle2 Keyboard: Linux Fix

Someone who found my original post about the Freestyle2’s dysfunctional media keys came up with a fix:

Kinesis Freestyle2 Media Keys
Kinesis Freestyle2 Media Keys

Some notes for the next time this comes up:

After doing sudo modprobe uinput, lsmod | grep uinp returns nothing at all (Xubuntu 16.04), but evtest seems perfectly happy:

sudo evtest /dev/input/event17
Input driver version is 1.0.1
Input device ID: bus 0x3 vendor 0x58f product 0x9410 version 0x0
Input device name: "KB800 Kinesis Freestyle"

And the keys work without any special configuration on my part. Apparently they’re already built into XFCE, despite the sound keys not showing up in the Keyboard Shortcuts control panel where you assign programs to keys.

This is wonderful work!

I’ve never seen so many calculators before! Oops.

There should be some udev-rule-ish way to automagically figure out which /dev/hidraw? device to use and symlink to a suitable alias, so the program could use it without knowing the actual device. A casual search turns up:

With which I’d produce /dev/input/kinesis0 and kinesis1, then use:

/home/ed/bin/kinesis/kfreestyle2d /dev/input/kinesis1

If only the Kinesis Fn key was momentary, rather than a push-on / push-off toggle. Le sigh. I can cope.
