What is the difference between the products with different PIDs?

What's this interface?

And what are these two for. Please include all interfaces in the
interface description above.

And please drop these in favour of using constants with a comment after
the first entry for the PID. For example:
{ USB_DEVICE_AND_INTERFACE_INFO(0x3731, 0x0100, 0xff, 0xff, 0x30) }, /* NetPrisma LCUK54 */
