Comment 311 for bug 268502

Usually, if I turn the laptop on with the bluetooth adaptor already plugged in, it works for a few moments, hcitool scan, pairing. After some bluetooth actions, the adaptor stops working with the message: kernel: hci_cmd_task: hci0 command tx.

If the adaptor is inserted after booting the laptop, usually it doesn't work and always shows the command tx error message when trying to scan, pairing or any other bluetooth action.
