hid-debug: input Button.00b2 = 0
hid-debug: input Button.00b4 = 0
hid-debug: input Button.0206 = 0
hid-debug: input Button.00b8 = 0
hid-debug: input Button.023d = 0

This is when I then release the volume key (Button.00E9 goes back to 0):

hid-core.c: report (size 4) (numbered)
hid-core.c: report 3 (size 3) =  00 00 00
hid-debug: input Button.018a = 0
hid-debug: input Button.0223 = 0
hid-debug: input Button.022a = 0
hid-debug: input Button.0221 = 0
hid-debug: input Button.0227 = 0
hid-debug: input Button.015c = 0
hid-debug: input Button.0225 = 0
hid-debug: input Button.0224 = 0
hid-debug: input Button.0183 = 0
hid-debug: input Button.00cd = 0
hid-debug: input Button.00b7 = 0
hid-debug: input Button.00b6 = 0
hid-debug: input Button.00b5 = 0
hid-debug: input Button.00e9 = 0
hid-debug: input Button.00ea = 0
hid-debug: input Button.00e2 = 0
hid-debug: input Button.0194 = 0
hid-debug: input Button.0192 = 0
hid-debug: input Button.0034 = 0
hid-debug: input Button.00b2 = 0
hid-debug: input Button.00b4 = 0
hid-debug: input Button.0206 = 0
hid-debug: input Button.00b8 = 0
hid-debug: input Button.023d = 0


The other keys follow the same pattern, with the following values (all
are "standard" values):

W		156
Ex		157
P		158

Back		224
Forward		225
Cancel		15c
Reload		227
Search		221
Favourites	22a

www		223
email		18A
file manager	194

music		183
mute		e2
playpause	cd
back		b6
forward		b5
stop		b7
volume up	e9
volume down	ea

Maybe a new kind of quirk is necessary for this keyboard which changes
Button.xxx events into Key.xxx events?

Thanks,
Pista
