I also have this problem with kernel 2.6.27.4.
hci_cmd_task: hci0 command tx timeout btusb_intr_complete: hci0 urb failed to resubmit (19)
Things like that.
After replacing the bluetooth subsystem with the codes from 2.6.26.7 and recompiling the kernel, the problem is solved. My bluetooth mouse works again on "2.6.27.4".
My adapter is a KY-BT100 one.
