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

Yes, that's exactly as expected. Do you have cheese or another webcam application installed? What do they say when you unbind uvcvideo driver from "1-1.3:1.0"? Mine says - "No video device found" (or something similar).

I'm wondering how different the bus/device handling on two different machines can be when their logical arrangement seems same !

PS:
My laptop is an Asus X54C - SX261D by the way. Not that it matters.

sorry do delay I was busy with other stuff

Could we come back to this issue. It seems it is still there.

Last point was to unbind video cam:

Code:

lech@HP-EliteBook:~$ echo -n "1-1.3:1.0" | sudo tee /sys/bus/pci/drivers/ehci_hcd/unbind
tee: /sys/bus/pci/drivers/ehci_hcd/unbind: No such file or directory

It does not work

Not ehci_hcd, it was uvcvideo. If you tried ehci_hcd, it was wrong, try the correct one - uvcvideo - as in my post.

However, it the mistake is just in your post and you already tried the correct form, then

Means the webcam applications can still detect and use it?

If so, assuming the webcam is controlled by (ONLY) uvcvideo driver, since the only other device in "/sys/bus/usb/drivers/uvcvideo" directory is "1-1.3:1.1", please try instead :

Code:

echo -n "1-1.3:1.1" | sudo tee /sys/bus/usb/drivers/uvcvideo/unbind
echo -n "1-1.3:1.1" | sudo tee /sys/bus/usb/drivers/uvcvideo/bind

..and check the webcam again if it is disabled after the first command, and its ID changed after the 2nd.

Guys just I would like to add I have the very same issue with a multilaser bluetooth mouse, I am also following your discussion, but so far couldn't find an answer either. Oh, and I get the very same behaviour, when I close and open the lid, the mouse comes back. It is interesting how frequently that affects other people, googling a bit you can find this out, but no answer for the problem, though.

Hi,
I've the same problem, Toshiba Satellite Pro C850 series notebook and Dell Bluetooth Travel mouse with Ubuntu 13.04 x64.

However, the problem occurs only when the notebook is running on battery. The problem does not occur if the laptop is connected to the power supply.

BR,
Alessio

Hey,
I don't know whether this could be a solution/workaround, but it helped me. Have a look at cuichi's answer here: http://askubuntu.com/questions/28611.../345871#345871

Same issue with Lenovo Yoga Pro 2. I've tried a bunch of things and so far nothing.. [SOLUTION BELOW]

UPDATE #1:

So far this seems to work for me:

echo -1 | sudo tee /sys/bus/usb/devices/2-4/power/autosuspend_delay_ms

(where 2-4 is the USB id of the bluetooth card)

UPDATE #2:

I had what felt like it should have been a disconnect and the mouse wouldn't work for a couple of seconds but then it recovered!

The log showed this:

Code:

Feb 12 10:21:44 riker kernel: [ 5533.421298] hid-generic 0005:0A5C:0001.0008: unknown main item tag 0x0
Feb 12 10:21:44 riker kernel: [ 5533.489341] input: Bluetooth 3.0 mouse as /devices/pci0000:00/0000:00:14.0/usb2/2-4/2-4:1.0/bluetooth/hci0/hci0:256/input18

Will update again if an actual disconnect happens.

UPDATE #3:

After a whole day without disconnects, I'm relatively convinced that it works!

I added the following to my rc.local:

Code:

# Prevents the Bluetooth USB card from getting reset which disconnects the mouse
BTUSB_DEV="8087:07dc"
BTUSB_BINDING="$(lsusb -d "$BTUSB_DEV" |
    cut -f 1 -d : |
    sed -e 's,Bus ,,' -e 's, Device ,/,' |
    xargs -I {} udevadm info -q path -n /dev/bus/usb/{} |
    xargs basename)"


echo "Disabling autosuspend for Bluetooth USB Soundcard: $BTUSB_BINDING..."
echo -1 > "/sys/bus/usb/devices/$BTUSB_BINDING/power/autosuspend_delay_ms"

Pls post if this works/doesn't for you.

HP EliteBook 850G1 + Mouse Bluetooth "HP Touch to Pair Mouse", frequent disconnect. Tried to upgrade latest kernel version and latest firmware version, without resolve the problem. Your script seems to resolve my problem: bravo, thank you very much.
