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
