My USB joystick "Primax Raptor 3D USB" worked improperly. I found out a
wrong usb report descriptor. Below you find a patch to correct this.
Unfortunately I don't know anyone with the same hardware for co-testing.
If you have access to this hardware, please check the patch and reply
results. Thank you!
The base of the patch ist the rpm version kernel-source-2.6.27.23-0.1.1 of
my system OpenSuse 11.1
kind regards!
Ralf
