Add an entry to the quirks-table to for usb-audio to recognize the Microbook II (although it only exposes vendor interfaces). A simple boot quirk is also implemented to set up the sample rate and make sure that no audio urbs are sent before the device is ready.
This patch only provides audio playback and capture at 96kHz sample rate. Notice the following shortcomings:
- The sample rate is currently hardcoded to 96k although the device
also supports 48k and 44.1k.
- The various mixer controls of the MicroBook are not made
available.
- The keep-iface control should be on by default because the device shuts down whenever the altsetting is reset which is usually
unwanted. (I don't know the best way to do this)
Can be set either in the quirk callback you write. Or it'd be not bad to create a white list, too.
I will try to address that in a future patch.
I have fixed the patch to address your remaining concerns.
