To know if the device is "win7 compliant" or not, we need the full output of lsusb (with the report descriptors). You need to tell usbhid to release the device before calling lsusb -v. Please use the script at http://lii-enac.fr/en/architecture/linux-input/report.py and run, as root: python report.py > descriptors.txt This will do the job. You can then send us the descriptors.txt, and we will see what we can do. > >> Using kernel 2.6.38-rc2-git5 (from Fedora rawhide). If your device is "win7 compliant" you will have to recompile a new kernel.
