Is there a reason you are seeing so many different vendor values - surely
you should see a single 'Digium' subvendor, and various subdevice values ?

That might be better as a table. You can then als include the name and
match details in the report which will help diagnose problems with it eg

	struct whatever {
		u16 svid, sdid;
		const char *name;
	}

And then print

	netjet: %s card is not supported by this driver (%04X, %04X).\n", 
		name, svid, sdid

		
Then again we don't seem to have a driver for these other kernel devices
so perhaps the safe default would be to warn and continue unless a module
option is set. At least initially.
