an manual reset is not possible. The HCI_RESET quirk only end up sending
HCI Reset as the first command. This actually only resets the Bluetooth
chip and nothing on the USB bus. Only in cases of Broadcom HID proxy it
triggers the HID to HCI switch.

I am simply not convinced that this is a HID proxy adapter and thus this
patch is not needed at all.

Marcel
