[Bug 268502] Re: Bluetooth doesn't work (hci_cmd_task: hci0 command tx timeout)

@Dominique Meeùs

Thankyou!! ~7months later my bluetooth keyboard&mouse finnally works
with latest kernel + your work around.

@ Ian M. Stewart

You might be missing a step or two. For reference my complete steps are:

1. sudo /etc/init.d/bluetooth stop
2. <unplug your bluetooth dongle and plug it back in now>
3. sudo hciconfig hci0 up
4. hciconfig -a
5. sudo hcitool scan
6. sudo hidd --search 00:07:61:9D:87:66

(Yes i'm using hidd from bluez-compat to connect, I don't know how else
to connect)


For interest here's the full log:

Ok lets try turning off bluetoothd.


$ sudo /etc/init.d/bluetooth stop
