    [ALSA] usb-audio - Support for Roland SonicCell sound module
    
    Added entry into usbquirks.h to recognize Roland SonicCell sound module by
    mostly duplicating the entry for the Roland SH-201. USB MIDI works just fine,
    though the USB audio is a little unreliable (but still works well enough).
