I just got a Radica "RacePac Steering Wheel" xbox controller. The USB
IDs weren't listed in xpad.c, so I added them there. It's listed as
having a 3 port hub, but as far as I can tell, it only has the wheel,
pedals and a dozen buttons (OK, a pad, the x,a,b,y four paddles, two
triggers 4 additional buttons on the spokes. Plus three more buttons
for adjusting sensitivies of various sorts.), plus a card reader of some
sort (for the xbox I presume) that might show up as a USB device on it's
own (thus the hub?).
The wheel counts as one axis, the pedals each show up as an axis, the
pad shows up as two axes. Some of the other buttons show up on axes as
well, plus as buttons. It seems odd/amazing to me that the buttons seem
to have some level of distance/pressure sensitivity. Is this normal?
Is there anything I can/should do to help the development of the xpad
driver for this device? Is this the right place to ask?
Here's the output from lsusb -vv:
