Subject: [PATCH] fix(linux): libinput "disable while typing" while kanata is
 running (#661)

Change virtual output device's bus_type from BUS_USB to BUS_I8042.

This fixes the dwt issues for me on Hyprland and I haven't noticed any
regression caused by this change.

Tested manually in Hyprland with `disable_while_typing=1`

Closes #548
Closes #659
