Hello,

> my keyboard works now fine, but I found keys which doesn't. Looks like MS 
> changed scan codes for them.

I have had this kind of problem with a Logitech diNovo Media Desktop
(http://www.logitech.com/bluetooth/). My main problems where that some
keys are not mapped correctly in the bthid-0.6 of Peter, and the code
for the mouse buttons is not OK. (at least with my Logitech Bluetooth
mouse).

The problem with the keys is that my keyboard is a swiss french one, and
the code of Peter has some keys missing. I have take the mapping from
the USB driver, and it is now working great. :-)

I have send my patches to Peter, but I have receive no answer. So, I
have attached my previous email to him. Try the patches to see if this
correct also your problem.

Good day.

Hi Peter,

first, thanks for your bthid software. I'm trying to use it with a
Logitech bluetooth keyboard. (see http://www.logitech.com/bluetooth for
more information on it). but don't search it on the market at this
time, it is not available now. I have one sample because we work with
Logitech on it.

I have try to use bthid-0.6 today with my Debian 2.4.21-mh2 system.
Connecting the keyboard/mouse is sometime ok, sometime not. But this is
not a problem at this time, and I will search the reason why the
connection is not always ok later.

The first "major" problem I was having is with the button 1 of the
mouse. It doesn't work. I see the bluetooth packets, but nothing in X. I
have do some debuging, and all is ok now. :-) The problem was with the
number of buttons of the Logitech mouse : 8 buttons:
- 1: left
- 2: right
- 3: middle
- 4: side 1 (SIDE)
- 5: side 2 (EXTRA)
- 6: top (don't know the function, maybe "new window")
- 7: forward
- 8: backward
and the wheel.

Your code was mapping unknown button (in this case top, forward and
backward) to "primary" button left. And, as when I use the mouse all the
"buttons events" are sent to bthid whith theyre state, the buttons 6, 7
and 8 cleared the 1, event if the 1 is setted.

The attached patch correct this. Note I'm not sure this will be
necessary with the public product, as mine are alpha release product
with alpha firmeware. But if the mouse send all the buttons when one has
is state changed, this patch is necessary.

Another problem I have is the key < and > are not working. The layout of
my keyboard is fr_CH (Swiss French), and the key with < and > is on the
bottom line. Here is the bottom line:

lowercase:
SHIFT < y x c v b n m , . - SHIFT
uppercase:
SHIFT > Y X C V B N M ; : _ SHIFT

The key with the  < and > has also the \ with the Alt Gr mode.

Here is the hcidump when I press and release the < key:

> ACL data: handle 0x002e flags 0x02 dlen 14
    L2CAP(d): cid 0x41 len 10 [psm 19]
      A1 01 00 00 64 00 00 00 00 00 
> ACL data: handle 0x002e flags 0x02 dlen 14
    L2CAP(d): cid 0x41 len 10 [psm 19]
      A1 01 00 00 00 00 00 00 00 00 

I suspect I must put something in the array hid_to_linux[], position
0x64, but I don't have search what to put at this time. (maybe next
patch ;-), but another day: I must go to sleep now. )

Other normal keys seems to work ok.

Last point. I will be happy if I can try to use the "hotkeys". I have
see this must be supported, but I don't known how. I have installed the
hotkeys package, but as I have no experience with hotkeys, I don't know
how to use it. I have try to start with:
hotkeys --type=logitech-cfo --osd=on -b --loglevel=7
but I see only the splash screen, and nothing else. The keys are routed
on the bluetooth layer, here is the hcidump -x of the "home" key:

> ACL data: handle 0x002e flags 0x02 dlen 10
    L2CAP(d): cid 0x41 len 6 [psm 19]
      A1 03 23 02 00 00 
> ACL data: handle 0x002e flags 0x02 dlen 10
    L2CAP(d): cid 0x41 len 6 [psm 19]
      A1 03 00 00 00 00 

Can you help me with this feature ?

Thanks in advance for your help. And thanks for bthid.

I have find a solution for this problem: use the same array as the usb
one (hid_keyboard from /usr/src/linux/drivers/usb/hid-input.c). This is
working great for me will all the "normal" keys. (don't know how to
enable hotkeys).

The patch for this is attached.

Good day.
