Wanting to give my Lenovo B590 new life, I recently installed Ubuntu 16.04 on it. However, Bluetooth does not work at all anymore; indeed, running lsusb yields

As you see, the built-in Broadcom Bluetooth 4.­0 is not detected at all, hence I could not follow this other guide. None of the other guides I have found helped much, either; many were technical and aimed at older versions of Ubuntu or were not useful for other reasons. How can I get Bluetooth working? Complete step-by-step guides are very welcome and might be awarded.

Update: As requested in the comments, I provide the output of dmesg | grep -i blue:

  • You can run usb-devices and find which one is your BT device. I suspect 04ca:2007. ;-) – Pilot6 Aug 20 '16 at 16:06
  • Thanks, it seems you are right. :-) And then that guide should work? – Gaussler Aug 20 '16 at 17:20
  • Correct. Now use that guide. BTW my answer has the information on how to find out which device is the BT, if it is not stated in lsusb. – Pilot6 Aug 20 '16 at 17:22

  • @Pilot6 By the way, my laptop runs 64 bit. So I assume I should look into bcbtums-win8x64-brcm.inf instead of the one with 86 in it? – Gaussler Aug 20 '16 at 17:31
