Control request looks like generic UAC_SET_CUR request, but with a bit
weird values,
valid values are { 0x01, 0x01} and { 0x01, 0x02 }, and there's no such
control type ATM.
I'm not well familiar with UAC so any suggestins how to get rid of
custom control req are welcome!
snd_usb_ctl_msg() call should be rewritten not to pass magic numbers but use constants, e.g. 0x01 = UAC_SET_CUR, 0x21 = USB_RECIP_INTERFACE | USB_TYPE_CLASS | USB_DIR_OUT ...
OK, but how to interpret wIndex and wValue values?
Depends :)

And, in this case, it'd be more natural to implement as an enum control instead of a switch.
OK
thanks,
Takashi
Thanks for review!
