Well, tell me what to try to determine where the cause is. Surely it
should be possible to instrument the kernel functions to gather more
information about the problem? Then we can say "yes, it's the

hci0: Type: USB
BD Address: 00:02:72:01:E5:FF ACL MTU: 192:8 SCO MTU: 64:8
HCI 16.4
Chip version: BlueCore02
Max key size: 56 bit
SCO mapping: HCI
Does that help? (any good?)
