• FreeBSD 14.1 (Xfce)
• Microsoft Sidewinder Precision Pro (USB)

• Joysticks on FreeBSD need to be at /dev/uhid# ¹⁾
• 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, if it had evdev or joystick forced through xorg.conf that driver gets unloaded according to Xorg.0.log

uhidd -h -H 'uhid' -u '/dev/ugen0.6'

• TODO: Figure out if ugen match is required (works fine without it)
