I can get all of the "extra" keys on my keyboards, with UHCI and OHCI on a
little endian machine. I think that the endianness issues have all been sorted
for HID, so I can't see that it would make any difference.
Can you confirm that they are not seen with event interface? Some keyboards
have this on a second interface, which may not appear as a keyboard. For
example, the following extract from /proc/bus/usb/devices on this machine.
T: Bus=01 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#= 3 Spd=1.5 MxCh= 0
D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=045e ProdID=001d Rev= 1.11
S: Product=Microsoft Natural Keyboard Pro
C:* #Ifs= 2 Cfg#= 1 Atr=a0 MxPwr=100mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=01 Prot=01 Driver=hid
E: Ad=81(I) Atr=03(Int.) MxPS= 8 Ivl= 10ms
I: If#= 1 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=00 Prot=00 Driver=hid
E: Ad=82(I) Atr=03(Int.) MxPS= 3 Ivl= 10ms
Note the two interfaces.
So you need to check /dev/input/event0 and also /dev/input/event1 (evtest is
good, cat is OK), assuming that these are the only HID devices on your
machine.
