[Bug 1469145] Re: Bluetooth device sometimes instantly turns off again after turning it on

 

Jonas Thiem, as per http://support.lenovo.com/us/en/products/laptops-
and-netbooks/thinkpad-x-series-laptops/thinkpad-x220 an update to your
computer's buggy and outdated BIOS is available (1.40). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then
please mark this report Status Confirmed.

Thank you for your understanding.

Title:
  Bluetooth device sometimes instantly turns off again after turning it
  on

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Sometimes when turning on bluetooth in the gnome bluetooth panel, it
  is shown as "On" for like a second and reverts back to "Off". This is
  what I see in dmesg:

  [1199362.625284] usb 1-1.4: Product: Broadcom Bluetooth Device
  [1199362.625286] usb 1-1.4: Manufacturer: Broadcom Corp
  [1199362.625287] usb 1-1.4: SerialNumber: EC55F9EFBB65
  [1199362.839031] usb 1-1.4: USB disconnect, device number 10
  [1199371.232776] usb 1-1.4: new full-speed USB device number 11 using ehci-pci
  [1199371.330552] usb 1-1.4: New USB device found, idVendor=0a5c, idProduct=217f
  [1199371.330556] usb 1-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
  [1199371.330559] usb 1-1.4: Product: Broadcom Bluetooth Device
  [1199371.330560] usb 1-1.4: Manufacturer: Broadcom Corp
  [1199371.330562] usb 1-1.4: SerialNumber: EC55F9EFBB65
  [1199371.544424] usb 1-1.4: USB disconnect, device number 11

  This situation is usually triggered after waking up from suspend, and then permanent up to the next reboot.
  I would assume the USB disconnect is the problem. I don't have bluetooth disabled in the BIOS settings.
