Bluetooth mouse stops to work after random time Ubuntu 13.04 on laptop

[macmus]

Hi,

Recently I bought bluetooth mouse as an addition to my ubuntu 13.04 with xfce.
The mouse paired strait away and kept going for some time.
After some time it lost a connection. Restarts of hcpi, deamon or even try to rediscover did not help.
The only cure was to restart my laptop, where everthing started to work (again for some time and then it stops)

When mouse stops to work in dmesg i see:

[  912.557942] Bluetooth: hci0 corrupted ACL packet
[  912.557990] Bluetooth: hci0 ACL packet for unknown connection handle 12

[  945.556801] Bluetooth: hci0 ACL packet for unknown connection handle 12
[  945.556805] Bluetooth: hci0 ACL packet for unknown connection handle 1

when i move mouse i see it tried to recconect. The dialog is stuck on "Remote Name Req Complet" for some time.
And then there is a disconect, and again mouse tries to reconnect.

When I remove the mouse and try to add it again I see it response but in linux the message show up that there was no response from applciation.

I would appreciate your help in this topic.

I know this sounds insane and could be right off the money, but ...

My wife just bought a wireless mouse that had me bamboozled. After a short period of time, the mouse switches off to save battery power. To get it alive again you need to press the scroll wheel. Have you tried that? Does the mouse work fine then when you have a break and go back to it, it has stopped working?

As I say, could be totally off the mark just trying to help ...

. After a short period of time, the mouse switches off to save battery power.

Well as you can see there are events coming to laptop when I move mouse so i don't think that is a problem here.

How else I can check logs for bluetooth, maybe it's conflicting with something etc..

instead of 16 which is suppose to be assigned to bluetooth mouse.

Any reason why all of the suddent 12 take over handler from 16 ? Do I get this behaviour right ?

[varunendra]

..it seems that for some magical reason it disapears from there at some point.

Maybe connection error, bad packets, driver crash.... who knows? I don't.

As for the connection handler, I don't even understand most of it. All I know is that in my experiments, resetting the hub on which bluetooth resides resets bluetooth itself, and the adapter starts working again. However, the connected devices need to be connected again. If this connection is done automatically, then a power-cycle on the mouse should do the job. Definitely annoying, but still better than a system reboot

The USB hub in your case is "0000:00:1d.0" -

[  218.865405] input: Dell BT Travel Mouse as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.6/2-1.6:1.0/bluetooth/hci0/hci0:12/input16

So you may try-

echo -n "0000:00:1d.0" | sudo tee /sys/bus/pci/drivers/ehci_hcd/unbind

then -

echo -n "0000:00:1d.0" | sudo tee /sys/bus/pci/drivers/ehci_hcd/bind

If you find an explanation to why the problem occurs, please share with us. Thanks!

Uh.. it was an assumption, I forgot to ask to confirm which one you have in use. It maybe uhci, xhci.. just run -
[code]usb-devices[code]
to see which one is used for that bus. Replace ehci with that one.

Now it's getting 'little' over my head. The output of usb-devices (and standard way of calling it) clearly lists the driver as "ehci_hcd".

Anyway, if you really actually tried the commands in the above sequence, you ended up 'removing' the driver from the bus. The sequence of running those commands should be opposite (first you 'unbind', THEN 'bind' again). This is in consistence to your statement that the command (sequence) makes it gone, and only a reboot enables it again.

Also, since I'm not sure about whether we got it right, I think you should manually browse to the /sys/bus/pci/drivers/ehci-pci/ directory, and see if the "0000:00:1d.0" 'link' appears there. If not, we're trying at a wrong address. (oh, but then again, that's the only address we've got ! So it must be the correct one !)
