Use the macros provided + * for that purpose if you can. + * + * The most specific match specifiers use device descriptor + * data.

These are used with single-function devices + * where bDeviceClass doesn't specify that each interface has + * its own class. + * + * Matches based on interface class/subclass/protocol are the + * most general; they let drivers bind to any interface on a + * multiple-function device. Use the USB_INTERFACE_INFO + * macro, or its siblings, to match class-per-interface style + * devices (as recorded in bDeviceClass). + * + * Within those groups, remember that not all combinations are + * meaningful.
