Agreed. Then the only thing is to create a cross reference of PnP
identifiers and drivers. Should we add this to the driver compatibility

Note that this tool will (rightfully) discard a PnP answer if the CRC is
incorrect. The only UPS on hand that blurped out something which looked
like a PnP string, has a bad CRC. Now if it only would be a little more
verbose (even in debug mode, it isn't really) about what is going on,
that would have saved me a couple of hours searching for what went
wrong... :-)
