Thanks,

Jiri,

I've tried to follow the instructions in the README.keymap but when I 
run /lib/udev/keymap -i input/eventX against both of the event devices I 
get nothing out, not even the "unknown" message mentioned in the doc.

I'm not totally up to speed with this yet, but I think i may be down to 
the "e0x0ffbc0000 HID usage page" that Wayne mentioned earlier not being 
read by the input layer and passed to the udev layer. If this is the 
case then before udev can be used to make hardware like this work the 
input layer will need to add support for this page.

Thanks,

Ben

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.
