That's strange I did almost the same thing but I used windows 8 cp and=A0us=
btrace, but my problem was that I was always getting the i/o error in linux=
(it was the usbhid module).=A0=0A=0ACan you use a VM? Some VMs allow to con=
nect input devices directly to the guest os. I use vmware, enabled "Show al=
l input devices" in the usb option, and installed the windows drivers. You =
could also use usbmon to sniff the usb port.=A0=0A# modprobe usbmon=0A#=A0m=
