On GNU/Linux, wheel controls the mouse

[matlo]

For example with a DFGT, wheel axis and gas pedal control the pointer, and dial controls the mouse buttons.

This seems to be a side effect of changing USAGE_JOYSTICK and USAGE_GAMEPAD to USAGE_MULTIAXIS_CONTROLLER in the HID descriptor (in the gimxuhid library). This makes xinput create an extra mouse:

xinput --list
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Logitech Gaming Mouse G502                id=8    [slave  pointer  (2)]
⎜   ↳ Logitech Gaming Mouse G502                id=9    [slave  pointer  (2)]
⎜   ↳ Teensy Keyboard/Mouse/Joystick            id=11   [slave  pointer  (2)]
⎜   ↳ Belkin Belkin n52te                       id=13   [slave  pointer  (2)]
⎜   ↳ Driving Force GT                          id=16   [slave  pointer  (2)]

Work-arounds:

• specify window events as input and grab mouse
• run after each GIMX start: xinput disable "pointer:Driving Force GT"
• add /etc/X11/xorg.conf.d/gimx.conf with the following content:

  Section "InputClass"
  Identifier "Logitech wheels managed by the UHID driver"
  MatchUSBID "046d:c291|046d:c293|046d:c294|046d:c295|046d:c298|046d:c299|046d:c29a|046d:c29b|046d:ca03|046d:c260"
  Option     "Ignore" "true"
  EndSection
