[alsa-devel] force snd-usb-audio to use "Vendor Specific Class"

[Alexey Fisher]

Hallo all,
is there any way to force snd-usb-audio to use some "Vendor Specific
Class" device?
i currently got two webcams from my friends to take a look on. They are
cheep gspca based webcams with Mic. I wont to test if snd-usb-audio can
use it if i force it. Devices it self do not provide any hints for the
driver.

lsusb -vd 093a:2468 | grep -i class
  bDeviceClass          255 Vendor Specific Class
  bDeviceSubClass       255 Vendor Specific Subclass
      bInterfaceClass       255 Vendor Specific Class
      bInterfaceSubClass    255 Vendor Specific Subclass
