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

Hi again,

responding to my own email after studying fake.c : I got it to compile
on 2.6, but this code isn't able to run as module on 2.6 kernels, which
changed the module format.

Peter : do you plan a 2.6 version anytime soon ?

TIA,
Charles

I used Peter's code only once, but I remember that you must use -l to
fork a server process.

I have to test more. What is your command line for this ? I use
/data/util/bthid-0.8-2.6/bthid -m -d -p 600 00:07:61:08:7E:2E

I can read it, I will look at your articles, thx for the hint. I have
already seen a nice presentation which helped to understand the
bluetooth layers. A long time ago, I developped low-level code in Z80
assembler and C for embedded systems, so I'm not completely lost :-)

You do a very good job in that limited time, given all these beginners
like me asking basic stuff on mailing lists :-)

this shouldn't be needed, because the mouse reconnects if you start
moving it. The only thing you need is a HID server process on your host.

If you understand german you are in the lucky position that I have
written some articles for german magazines and most of them are also
available online.

The missing of a general white paper is a good point. I have thought so
many times about writing the one and only introduction into Linux and
Bluetooth, but always the same things stopped me from doing this. The
first is that no company pays me for working on BlueZ and so we come to
the second, that my time is very limited.

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

Hi Marcel and Olivier,

it works. Shame on me. Your remark about my empty link policy googled me
to another hcid.conf, and I suddenly saw mine, which was wrongly
configured, and worst, *hcid wasn't started*.

I'm running gentoo, and for some reason, there are no startup script for
bluetooth, so I was starting it by hand (hciconfig hci0 up).

Now, my mouse isn't jumpy at all anymore. The only glitch left is that I
have to press its "connect" button just after starting bthid if I want a
link. Is there a way to get this automated ?

I don't like to criticize about missing docs, because I have the same
problem at my main contract as Solaris admin (too many things to do to
write proper docs). However, bluez suffer a bit from that problem. They
are loads of small HOWTOs, but I miss a sort of white paper to explain
bluetooth in general. Any pointer is welcome.

Meanwhile, I'm still ready to test new versions of bthid or its future
replacement. Thanks a lot for your help. As soon as my last prob is
worked out (auto-connect of MX900), I'll finish my
"yet-another-bluez-mini-HOWTO" :-)

this is a HCI 16.5 with 128 bit encryption and it should work fine. The
problematic part is maybe that you have no link policy set. The minimum
options should be rswitch and sniff. Please use

http://www.holtmann.org/linux/bluetooth/btdfu-0.2.tar.gz

to extract your firmware and send it to me.

what kind of Bluetooth adapter do you use? I had some problem with CSR
chips and old firmwares.

Hi Olivier,

Thanks for your answer. I don't run GPM, so the problem isn't from
there. But you gave me another idea : I loaded my modules, started the
patched bthid, exited X, and tried gpm in console. I got the same
problem !!! The mouse is jumpy as well. I think I can now exclude Xfree
from the potential problem.

I guess bthid is producing the jumpy mouse. I tried to checkout the CVS
version, but I'm lost with autoconf and friends. I guess I will have to
wait for Marcel's new snapshot.

What frustrate me is that I got it working twice last week, after
unloading/loading stopping/starting it several times, but I lost the
order and options I had.

Well, we it works, we all have to get a good beer :-)

I have add this kind of problem with my USB mouse long time ago. This
was because I have also gpm working (mouse usage in non grphical
session). I you need to use gpm at the same time of XFree, you need to
search on the web, as there is some special config to do. A quick search
on google give lot of tips for this config. For example
http://linuxfromscratch.org/pipermail/blfs-dev/2003-April/002637.html

Maybe you have installed gpm ?

> command line, etc ?

I think as you have it working (maybe bad, but working), your bluetooth
config is OK (hciconfig command, loaded modules). For the bthid command
line, I have modified the /etc/init.d/bluetooth-hid file for having the
command line:

bthid -m -l -s

I think you need CONFIG_INPUT_MOUSEDEV, but I'm not sure. I have it in
module. (but as I also have a USB mouse, I really need it).

> should I remove this ?

Because XF86Config-4 use /dev/input/mice, I think you really need it.

Good day.

Hi Olivier,

I tried your config, the wheel now works OK. Thanks a lot.

Another problem appeared after my initial email : the mouse movements
are showing sudden accelerations. Makes it difficult to use. I tried
several protocols in XF86Config-4, no difference.

I re-emerged Xfree without the patch, the problem persist.

I find this strange, as yesterday evening, the mouse suddenly worked
fine... I'm getting confused.

Could you provide your setup ? hciconfig command, loaded modules, bthid
command line, etc ?

Another question : do I need MOUSEDEV in my kernel ? I have

CONFIG_INPUT_MOUSEDEV=y
CONFIG_INPUT_MOUSEDEV_PSAUX=y
CONFIG_INPUT_MOUSEDEV_SCREEN_X=1920
CONFIG_INPUT_MOUSEDEV_SCREEN_Y=1200

should I remove this ?

TIA,
Charles

I don't use devfs and this is what I have in /dev

crw-rw-rw- 1 root root 10, 223 Aug 31 22:05 /dev/input/uinput

You can use mknod for creating it. Maybe your devfs problem is a
permission problem.

Usualy, the ZAxisMapping in on the buttons 4 and 5. Here is my

With this config, the mouse wheel is working ok.

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

Hi,

I have still some small glitches with my MX900. I have done the
following procedure :

1. XFree patch

I patched my XFree (gentoo xfree-4.3.99.16) with this patch
(http://www.yhbt.net/normalperson/files/linux/LogitechMX_kernel_and_X_patch/4.3.0-XFree86_logitech_ps2.patch), to make it understand PS/2+ protocol. Do I need this for the MX900 ?

2. bthid patches

- started with the bthid 0.8 stock source
- applied Edd Dumbill's uinput patch
- applied Olivier Bornet's patch-bthid-0.6-for-lt.txt
- modified out.c to use /dev/misc/uinput (Marcel says devfs produce
this, I don't see exactly what I do wrong or what I should do to get
/dev/input/uinput).

3. XF86Config-4

--------
Section "InputDevice"
Identifier "LogitechUSBMouse"
Driver "mouse"
Option "Protocol" "ExplorerPS/2"
Option "Device" "/dev/input/mice"
Option "ZAxisMapping" "7 8"
Option "Resolution" "800"
Option "SmartScroll" "1"
Option "Buttons" "8"
Option "Emulate3Buttons" "false"
EndSection
----------------

works :

- mouse movements : clean, precise, perfect
- buttons : 1,2,3 (2 = wheel-press)

problems :

- wheel doesn't work, even if I see button-7 and button-8 in xev output when I move the wheel.

do I use the correct protocol ?

Hints welcome...

TIA,
Charles

maybe someone with very good HID knowledge can decode the HID descriptor
and find an answer. Or we must use a protocol analyser to sniff the HIDP
packets.

I have some response from CSR according the switch from HID to HCI mode.
This fits perfect for the EPoX dongle, but the Logitech dongle is quite
more complex. It presents a USB hub, two USB HID devices and four extra
HID devices with Windows XP.

However I actually don't how to implement the switch in Linux by now,
but I will take a look at it.

Unfortunately, no. Has far as I known, this is not part of the HID
profile. This is a "special" modified version by Logitech. I already
have asked for this, without success at this time.

Also, for switching from USB to BT the "Bluetooth HUB", I will look with
Logitech if we can have the specification for doing this switch. Hope I
will have more success.

Good day.

Hi Olivier,

I have tested it with the Microsoft, the Logitech and the EPoX mouse.
All of them are working fine now. I can't tell you much for the keyboard
layout patch, because my Microsoft keyboard has an UK layout and the
EPoX has an US layout. Only the diNovo keyboard uses a German layout and
this is working fine for me.

Do you know how to access the display of the diNovo mediapad?

Since about 2 month now, I'm using bthid from Peter with a diNovo
desktop. This include the MX900 mouse. All is working OK. But...

But it requiere some patching...

October 13, I have send a patch to Peter for the mouse button problems.
See the two first email attached. No answer at all from Peter...
This is against version 0.6 of bthid, but this is a very simple patch,
so it must be easy to put in on the last release of bthid. The major
problem is that the MX900 send all the button status when there is a
change. And because if a button is not recognized by bthid, it was
assigning it by default to the button 1. Has the MX900 has more buttons
than bthid think. So, button 1 is always not pressed... (see attached
emails for more info).

October 18, I have send a patch for non-US keyboard. This was used by
another guy on bluez-users. Again, no answer from Peter... See 3rd email
attached to this one.

October 28, I have send the patches on the bluez-users list. No answer
from Peter... (see mailing list archive to find my message)

Here is another try (on bluez-devel this time). Thanks to let me known
what is bad with my patches. I'm sure if you will be put them in bthid,
people using Logitech deviceces will be happy. And also people using
non-us keyboard.

Good day.

no. I have the same problem with the Logitech MX900 mouse. It must be a
bug in the HID parser or in the HID descriptor of the device.

Hi,

[first, thanks a lot for helping me. I plan a mini-HOWTO ln a web page
when I'm done so other can get the same setup working.]

I tried your patch on my linux-2.6.0-test11-gentoo Dell I8600 with my
Logitech MX900 mouse. It applies OK, but (don't know if it's gentoo
specific), my uinput is at /dev/misc/uinput, not /dev/input/uinput. So I
had to fix the path in out.c.

After this, I get the mouse events in X. The movements are OK, but the
button 1 is not doing its job. If I cat < /dev/input/mice, I see
something happen when I click it, so it's obviously not the button
hardware.

I have compiled my X with a patch to enable the PS/2++ protocol. The
patch is from Eric Wong, can be downloaded here :
http://www.yhbt.net/normalperson/files/linux/LogitechMX_kernel_and_X_patch/4.3.0-XFree86_logitech_ps2.patch

could this patch be the reason for my button 1 problem ?

Hints welcome.
Charles

my problem is that it depends on static variables and I don't see any
method to create HID reports from input events that the kernel send to
us and we have to forward to the HID device. For exmaple the keyboard
leds.

I have rewritten my core HID layer which is now only one process with an
event loop. It handles all connection establishment and termination fine
without any problems or stalled ACL links. It also gets the vendor and
product ID's from the PNP information. Some minor things have to be
fixed first, but I think that I will commit it to CVS very soon. If this
code is available I hope we can work together on a full featured HID
parser implementation and I think we can use your current code as a
starting point.

Regards

Marcel
