This device has a trackstick that is sent through the same HID device

Unfortunately there are 2 mice attached to that device descriptor, with
the first one for the touchpad when the second is for the trackstick.

Force all devices to be exported.

FTR, this patch was already taken through
4eab1c2fe06c98a4dff258dd64800b6986c101e9, so we can safely ditch it.

Cheers,
Benjamin
