Already have it from my tweaks to the if_cdce driver.  For those who
might be following this thread, here are the values for my YP 3700:

	Vendor		0x22b8
	Product		0x4902
	Release		0x0001
	Class		0x0002
	Subclass	0x0000
	Protocol	0x0000

The Vendor and Product are the only values necessary for the driver;
and I suspect that in this case, there's no real advantage to specifying
any of the others in usbd.conf.

For completeness, I would be interested in obtaining values for the
YP 3500 and YP 3000.

Thanks, I'll give that a try after the holidays.  If I wind up going
that route instead of cdce, I will submit a PR with the YOPY's values.
