Problems with bluetooth/dbt-120

[Maximilian Gerlach]

Hi everyone,
I just don't get bluetooth working.
When I insert my dbt-120 (which I had working under debian, a long long
time ago) hci_usb gets loaded, but a hciconfig shows me 
        hci0:   Type: USB
                BD Address: 00:00:00:00:00:00 ACL MTU: 0:0  SCO MTU: 0:0
                DOWN
                RX bytes:0 acl:0 sco:0 events:0 errors:0
                TX bytes:0 acl:0 sco:0 commands:0 errors:0
and a  hciconfig hci0 up brings this message:
	Can't init device hci0. Input/output error(5)
Any ideas?

Thanks,
Maxi
