[Bluez-users] MS multimedia keys

[Bluez-users] MS multimedia keys

[Walt]

I have the ms bluetooth wireless desktop.  I was using kernel 2.6.7 
patched, hidd  and hidp, and everything was fine.  I upgraded to 2.6.8, 
first rc2 and now final, and the multimedia stopped working.  I checked 
hcidump, and those keys, as well as the alt. function f* keys, dont 
produce output. 
Thanks
Walt

Use kernel 2.6.8-mh1, because the report protocol mode is not yet ready
for mainline. If you use a plain 2.6.8 you only get boot protocol mode
support.

this problem is because in drivers/char/keyboard.c the x86_keycodes[256]
array miss the line for the last 16 keycode translations.

Vojtech, any reason why they are not filled in?

Marcel

Because rawmode only can express 240 different scancodes.

Marcel,

that means, that these keys will never work?

may you explain this a little bit. I found a posting from you on the
LKML where you said this has something do to with the PS/2 protocol, but
I still can't follow it.

The PS/2 protocol has valid keycodes in these two ranges:

	00 to 5f and e0 00 to e0 5f

The first is the classic XT set and the other is the extended set. Of
course there are exceptions and also some of the 60-7f and e060-e07f can
be used. This gives approximately 240 possible scancodes.

The table maps those 240 scancodes to the first 240 Linux keycodes.
Keycodes above this limit don't have any mapping, because it'd have to
be identical with some already used, or cause a protocol violation.

Marcel, 

so you must remap it to lower numbers first before you'll send it into 
keyboard.c???

> I posted list of these behavior few mounths ago, search mailing list.

this is true and I had it on my todo list, but actually this has very
low priority. However the original problem was the missing report
protocol mode that is only part of 2.6.8-mh1.
