Hi Kees and all,
I've got a report from an end user that their Logitech F710 wireless
gamepad is not functioning correctly. This device has a switch to select
between 'X' mode (X-Pad, works OK) and 'D' mode (HID using hid-logitech,
doesn't work).
After some discussion off list, Elias and I think that this is related to
checking the report descriptor (attached).

Last message comes from here (I believe):
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/hid/hid-lgff.c?id=refs/tags/v3.15-rc1#n137
Can anyone see what might be wrong with the report, to cause this code to
spit out an error?
Cheers,
Simon.
