Hi,
The 'hid-lgff.c' driver supports lots of devices (see end of 'hid-lg.c'),
and presumably these devices offer up a wide/varied range of HID
descriptors.

Does the recently introduced(/changed) check need to have prior knowledge
of which 'Report ID's are actually used? If so, it possible that the
change has broken a number of devices...

I am trying to get the end user to test with an older kernel to see
whether his device was always 'broken'.

Thanks.
Simon
