I have a built-in USB device, lsusb | grep "bluetooth" outputs:

Bus 002 Device 004: ID 413c:8187 Dell Computer Corp. DW375 Bluetooth Module

This device has hardware issues, it's not working reliably in Windows either. (It works in Linux after a

sudo hciconfig hci0 reset

, but after a suspend to ram, the device sometimes completely disappears, sometimes it can not be re-activated, issues, issues...)

I rather use an external Bluetooth dongle, but I do not want to waste battery power on this internal device.

Disabling in BIOS is no alternative, as the BIOS is password protected by company policy. Blacklisting?

EDIT: running latest BIOS firmware

  • btw: No such thing as InitiallyPowered under Ubuntu-MATE 16.04, but the Rest works fine. – Frank Nocke Sep 12 '17 at 12:19
