Title:
BT mouse getting reset during operation
Status in Linux:
Unknown
Status in linux package in Ubuntu:
Confirmed
Bug description:
(note: It's unclear to me if that's a kernel regression or an issue with
bluez)
I've been using this particular combination of Bluetooth mouse ("TECKNET
BM306") & laptop ("Dell Latitude E7240") for over a year now.
It used to work with 18.04 and 17.10, but with 18.10 I'm encountering
a strange disconnect behaviour:
1) Mouse is working ok
2) Mouse suddenly stops
3) Disabling and enabling bluetooth on the laptop makes the mouse work again.
when this happens, dmesg reports:
[57812.977570] usb 1-1.3: reset full-speed USB device number 18 using
ehci-pci
Disabling bluetooth and enabling it again results in:
[57833.455866] usb 1-1.3: USB disconnect, device number 18
[57833.455948] Bluetooth: hci0: turning off Intel device LED failed (-19)
