usb-mouse: do not set bDeviceClass in the device descriptor

Do not explicitly set the bDeviceClass attribute to USB_CLASS_HID for
usb-mouse device. Even if this would be compliant with USB standards,
some OSes (e.g., Mac OS X) don't properly recognize the device as a
valid USB mouse.

Setting the value to 0 fixes the problem.
