• Joysticks need to be at /dev/uhid#
• uhidd by-default does /dev/uvhid#, that can be symlinked to /dev/uhid# or be done automatically with uhidd -H uhid
• uhidd has a lot of flags in examples for keyboard/mouse/consumer, but a joystick only needs the virtual generic interface with uhidd -h
• uhidd has to unbind whatever is on the joystick with uhidd -u
• Seemingly once uhidd takes control of the original /dev/input/event# device evdev nor joystick modules work and get unloaded according to Xorg.0.log
• TODO: Put this somewhere outside of FlightGear
