Looks like USB problems to me. For some people it helps to switch from
usb-uhci.o to uhci.o.
Try if first.
You can also try to decrease number of outstanding bulk TX requests.
In the file drivers/bluetooth/hci_usb.h
Replace
#define HCI_MAX_BULK_TX 4
with
#define HCI_MAX_BULK_TX 1
Recompile and reload hci_usb module.
Does that help ?
