If you are interested what usages and collections are (and if you are
going to write the support for this device, you probably are :) ), please
see http://www.usb.org/developers/hidpage - namely
http://www.usb.org/developers/devclass_docs/HID1_11.pdf and possibly also
http://www.usb.org/developers/devclass_docs/Hut1_12.pdf

We don't want neither the 'Telephony' nor 'LEDs' usages to be claimed by
the hid-input system, that seems to make a little sense.
So either the device is bogus and has broken report descriptor (which we
could fix in runtime), or it really can't be handled by hid-input (I have
no idea about the purpose and internal working of the device in question,
sorry).
Either we can fix the hiddev_connect() so that the device would be claimed
by hiddev (*) and you can write the driver for this device easily in
userland, or you could try to write generic in-kernel hid-telephony.c
handler of all telephony devices (but I doubt this is doable in a
reasonable way).
(*) I currently have no idea why this device is not claimed by hiddev
though - it seems to have all collections of type
HID_COLLECTION_APPLICATION which obviously are not IS_INPUT_APPLICATION()
... could you please put debugging output into hiddev_connect() to examine
why your device is not being claimed by hiddev?
Thanks,
