I'm using Ubuntu Gnome 15.10 with Linux 4.2.0-22-generic #27-Ubuntu SMP Thu Dec 17 22:57:08 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux.
I cannot enable the Bluetooth device built-in my laptop Toshiba Satellite C845. It has a Toshiba ACPI Bluetooth device driver. There is a device hci0 which I get timeout after command:
$ hcitool scan
Scanning ...
Inquiry failed: Connection timed out
However, I get a MAC address:
$ hcitool dev
Devices:
hci0 44:6D:57:05:6A:81
I have this output from command:
$ dmesg | grep -i bluet

I understand there is a physical device which doesn't get a driver to operate. When I see the output of lsusb
, then I get:
Bus 003 Device 002: ID 0930:021d Toshiba Corp.
Device Descriptor:

... What is missing that I cannot load a driver/module to get enabled this bluetooth device? Is not Toshiba an Ubuntu-friendly manufacturer?
Any ideas, please?
