Thanks for the data. The "TV" key is indeed very strange, as there seems
to be report received, corresponding usbmon log:

de8ec680 1405369735 C Ii:2:014:2 0:8 3 = 064600
de8ec680 1405369751 S Ii:2:014:2 -115:8 5 <

but only the "release" report, that is sent just afterwards, seems to have
reached HID layer, I don't know why. Could you please test the patch
below, and send me the output?
