Hi Marcel,

so adding the broken ISOC quirk would be enough to make this dongle work
again. Maybe the last time I tested it, I had the SCO support disabled.

Is this something to add in the kernel settings?

What does "hciconfig hci0 revision" say? These versions look a little
bit wrong.

hciconfig hci0 revision
hci0:   Type: USB
        BD Address: 00:02:72:B3:43:18 ACL MTU: 377:10 SCO MTU: 16:0
        Unsupported manufacturer

Regards

Ben
