this is a broken chip anyway. The failure of HCI_Inquiry must be
answered with a HCI_Command_Status event and not a HCI_Command_Complete
event.
Is this another Broadcom based dongle?
Try loading the hci_usb with "reset=1" and post the content
of /proc/bus/usb/devices.
A thousand thanks for your answer. Yes, now I can see that it's a Broadcom BCM2045B2.
What's up with the "reset=1" parameter? I've now successfully paired it with a Nokia BH-300 Headset and have it working with the btsco tools. :) Wonderful.
Again, many thanks.

Arthur
