See attached; I detached the hid driver in linux to get this.
Everything looks OK; actually bDeviceClass was set to EFh
(miscellaneous), but changing it to 03h (HID) had no effect.
Still seems to work fine in linux, still no recognition from the windows
side.
If I comment out the joystick descriptor, and just leave the mouse, it's
recognized in windows as a "HID-compliant game controller", but I don't
get usb errors, or 'not recognized'. This may be a clue
Thanks for responding guys!
