[Bluez-users] Problems with MS mouse and keyboard

[Bluez-users] Problems with MS mouse and keyboard

[Gareth Reakes]

Hi all,
	I tried to get this all to work about 6 months ago and could not.
I have now tried again from scratch after the recent mail regarding this
subject. I have everything installed and a brand spanking new 2.4.22
kernel. I find it very difficult to connect and when I do connect it will
not maintain the connection. I know these devices go into sleep mode, but
talking to other people on this list, they come out of it. This is not
possible for me. Frequently, after I try to wiggle the mouse in sleep
mode, bthid start to take up 100% of the CPU. I find it unlikely that this
is the bthid code itself.
	It is more than possible that this is a hardware problem with my
mouse etc but I would really like to know this before trying to exchange
them. I do have 1 more piece of information with the new kernel. As you
can see at the end of the message below there is a message which may help.
I am willing and able to provide whatever information will help solve this
problem. I really do not want to lose against MS ;)

Any help is greatly appreciated,

Gareth

it looks like you lost the ACL link, but the mouse didn't know about
that and keeps sending you reports on that channel.

Do you get this working under Windows XP. If not, they are broken.

You are welcome :)

I will fish out the drivers and find someone with XP to test them. I will
hopefully do this next week and will give a shout back about success then.
However, I assume that the 100% CPU usage is not a good thing? I will
happily build this stuff up in debug mode and try and start it under gdb
to get a backtrace if this will be helpful for bluez development. Tell me
if there is anything I can do.

Thanks for your help,

Gareth

Re: [Bluez-users] Problems with MS mouse and keyboard

[Gareth Reakes]

Hey all,

	I thought I would give a quick update. M$ agreed within seconds
that there was a problem with the keyboard and mouse and promptly sent a
new one out! I have just recieved them and they do not work either :(
Exactly the same problem.

	I thought that I would give it a try with Marcels bthid. In his
previous mail he states that it relies on a modifcation to the USB HID
kernel module. Where is this in CVS? Also, do I have to do anything else
(like undo the things I did to make the original bthid work?) before this
should work?

Thanks,

Gareth

please check that it works with the Windows XP Bluetooth stack.

And here is the problem. This code is not available at the moment. I
have only one machine with a hacked USB HID driver and never found the
time to get this clean. You also have to install the new Bluetooth
library to make my bthid working, because the old SDP code can't get the
complete HID descriptor from the HID device.

Do anyone have interest in working on the HID kernel driver. My idea of
the interface for the bthid daemon is very easy. You will see it if you
look at the bthid source code. On request I can post some comments about
it.

Regards

Marcel

I am happy to put some time in. If you post some comments then I will try
and take a look later next week or on the weekend.

Once again, thanks for your help Marcel

I was really hoping it was not going to work. Unfortunately it does :( I
would really appreciate any help in sorting this out. I have rebuilt and
installed the bluez modules against my patched 2.4.22 kernel and all is
the same. The output from the 0.8 bthid is:

this is the implementation from Peter and I can't help you with it. I
have only used it once.

Re: [Bluez-users] Problems with MS mouse and keyboard

[Gareth Reakes]

Hey Michal,

	I know the ping thing works, however I don't believe that it
should be necessary. I think there is either something wrong with the
hardware, bthid or bluez. If it is bthid or bluez then I would like to try
and fix it so we can all benifit :)

look at my bthid code and see how I have handled it. This was working
for me. You need a sleep() and the correct order of closing the L2CAP
channels. Otherwise the ACL connection would not be terminated.

I modified my bthid code after you posted the other week. It still does
not work.  Ah well, this just gives me more incentive to work on the
kernel HID parser :) I will speak again after I have read your posting on
devel and had a go at implementing it.

Re: [Bluez-users] Problems with MS mouse and keyboard

[Michal Semler (volny.cz)]

Hi Gareth,

maybe Marcel should fetch and release from CVS his=20

hid-0.0.0.1-verysoon-notstable-onlyforinsane-prealfa version :)

Then will much more people test it and we'll get more feedback from users...

Marcel what do you think about it? :)

I won't do this, because the code depends on the new Bluetooth library
and this is not released.

Re: [Bluez-users] Problems with MS mouse and keyboard

[Gareth Reakes]

Hey,
	thanks for the response. Is there someway I can simulate this with
hcitool (or some other tool)? If I hcitool cc to this what would you
expect the behaveiour to be? The mouse will go to sleep in 12 mins, but if
I move it and to a hcitool con after that should the device appear? Or
would I have to connect again? I seem to recall that there was some way of
showing the incoming input from the connection. If I did this without
bthid, then would this establish if the problem was with bthid or bluez?

Once again, thanks for your help,

Gareth
