I'm not familiar with these kernel errors. The linux-bluetooth mailing
list would probably be a better place for this question:
http://vger.kernel.org/vger-lists.html#linux-bluetooth
This looks even further down the stack - the messages are from the USB
3.0 driver. It is probably a 2.0 device so you should better use a 2.0 port
(and the ehci_hcd driver).
I observed issues with 2.0 devices on 3.0 ports.
