Same issue here. Tried downgrading bluez to 4.32-0ubuntu4, but didn't help.
Adding some more information in case it's useful
System: Ubuntu 9.10
Hardware: Dynamode BT-USB-M2 (Cambridge Silicon Radio)
Symptom: Device is discovered when plugged in, but times out whenever I try to
access it (hcitool info, hcitool scan etc).
