kbluetoothd authentication failure

Hey guys,

Trying to setup kbluetoothd with my bluetooth headset, I had it connected not that long ago and after a reboot and using the bluetooth headset on another machine it no longer authenticates. It doesnt ask me for the pin either, and I cant seem to setup a new pin using the bluez-pin with bzaddr. I've also tried most of the other pin utils including making a .bash script file.

Perhaps some protocol or authentication type is missing I just cant tell. Unless the device itself has been altered by being paired with a windows machine. Take a look below for the config/debugging info.

Below is hcidump -X -V:-

shodan:/etc/bluetooth# hcidump -V -X

Error: Authentication Failure

You can see the link key requests taking place, Connect Complete, but then Authentication Failure, this is repeat continously.

Also tried enabling auth and encryption with same error results.

Using the hcitool produces:-

hcitool cc 00:0D:44:2F:8C:C0
Can't create connection: Input/output error

Thanks for any help you can give.
