HID: driver for BTC "Emprex 3009URF III Vista MCE Remote" quirky remote
The Behavior Tech. Computer Corp. (BTC) remote branded as "Emprex 3009URF III
Vista Remote Controller" uses non-standard mappings for all of its 'special
purpose' keys (0xffbc usage page). Applies cleanly to 2.6.30 and 2.6.32
(other versions not tested).
scripts/scriptpatch.pl reports 13 styling errors in hid-btc.c
("break;" should be on trailing lines)
but have not changed them to maintain styling consistency with existing drivers.
