[Bluez-devel] Logitech MX900 mouse with Dell Inspiron 8600

[Charles Bueche <charles@bueche.ch>]

Hi,

I have this hardware combination : the new Logitech MX900, which is
talking bluetooth to its hub. This hub goes to my laptop using USB.

I'm using gentoo linux, with kernel 2.6.0test11. I have patched my
XFree86 (xfree-4.3.99.16.ebuild) with
http://www.yhbt.net/normalperson/files/linux/LogitechMX_kernel_and_X_patch/
to make it understand the PS2++ protocol, and the mouse somewhat works.

The setup is working fine, even if I didn't finish the setup completely
(all buttons aren't working yet).

Now, having a internal bluetooth module within my Dell Inspiron 8600, I
would like to connect the mouse directly, without going through the hub
and USB.

When I use the basic tools (hcitool scan, hcitool info), I get this info
block from the mx900 :

==============
Requesting information ...
BD Address:  00:07:61:08:7E:2E
Device Name: Logitech MX900 Mouse
LMP Version: 1.1 (0x1) LMP Subversion: 0x350
Manufacturer: Cambridge Silicon Radio (10)
Features: 0xfc 0xff 0x0f 0x00
<encryption> <slot offset> <timing accuracy> <role switch> <hold mode>
<sniff mode> <park mode> <RSSI> <channel quality> <SCO link> <HV2
packets> <HV3 packets> <u-law log> <A-law log> <CVSD> <paging scheme>
<power control> <transparent SCO> 
==============

I now understand that I need some piece of software to get the mouse
events from the bluez stack and pass them to a device that X would
understand.

 I tried to compile bthid from Peter Klauser. bthid itself compile, but
fake.o choke on line 87 of fake.c :

====================
make -f make.fake fake.o
make[1]: Entering directory `/data/util/bthid-0.8'
gcc -pipe   -Iinclude/asm-i386/mach-default  -DMODULE -DMODVERSIONS
-include /usr/src/linux-2.6.0-test11-gentoo/include/config/modversions.h
-D__KERNEL__ -DMAJORNUM=250 -I/usr/src/linux-2.6.0-test11-gentoo/include
-fno-strict-aliasing -fno-common   -c -o fake.o fake.c
fake.c:86: parse error before "devfs_handle"
fake.c:86: warning: data definition has no type or storage class
make[1]: *** [fake.o] Error 1
make[1]: Leaving directory `/data/util/bthid-0.8'
make: *** [fake.o] Error 2
====================

hints welcome. I can test whatewer piece of code you throw at me. I'm
however not knowledeable enough to code it myself.

Charles
