G Pro force feedback support

[joebywan]

Driver's installed, and it's loading force feedback.

Not getting FFB with games on steam though.

Using https://github.com/sre/rumble-test it did cause force feedback on the wheel using

rumble-test /dev/input/event9 0xffff

Any suggestions on what to look at next?

Finally managed to get some FFWrap logs:

Ran:

/home/user/Documents/github/ffbtools/bin/ffbwrap --logger=./ /dev/input/by-id/usb-Logitech_PRO_Racing_Wheel_2421WD018AF8-event-joystick -- ./rumble-test /dev/input/event9 0xffff

Funnily enough before trying this a mate got me to play some wreckfest with him, and to my utter surprise, FFB worked.

Works:

Doesn't work:

To be clear, all of these worked on a G923. The last 2 don't work on the G pro, in Gpro or G923 mode.
