CSR is short for Cambridge Silicon Radio, which is a the OEM that makes most of the bluetooth audio chips in vendor hardware. The hardware vendor can enable or disable features on the CSR microcontroller depending on licensing options. The hardware vendor can also use a custom USB descriptor, or just set a custom PID. In the latter case we need to set the vendor and model to reality using quirks. This commit allows the user to update the firmware in the AIAIAI H05 wireless headphones.
