My bluetooth only works after suspending my computer. See just after starting my computer the output of rfkill list all is:

  $ rfkill list all
  0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

Then I suspend it (here I use pm-suspend, but the GUI method works too)

  # pm-suspend

and voilà, rfkill list all again

  $ rfkill list all
  0: phy0: Wireless LAN
       Soft blocked: no
       Hard blocked: no
  1: hci0: Bluetooth
       Soft blocked: no
       Hard blocked: no

the output of lspci is

Any ideas on what could be causing this?

Thanks!

  • Does it work without suspend if you sudo modprobe -r btusb && sleep 5 && sudo modprobe btusb – Jeremy31 Jul 14 '15 at 11:38
