No objection per se, I wanted to find out what descriptor field is
changed by the quirk, and where the crashes come from exactly. The

Daniel, this seems to be a regression introduced with the UAC2 changes.
The old driver accepted vendor-specific interfaces, if some quirk forced
it to look at them.
