That only works if you have useful things that the udev rules can
differentiate on to allow you to set the names.  Unfortunately, that
is not always the case - I think last time I looked, the only way I
had to differentiate my AverTV tuner from my Nova-TD ones was the PCI
and USB addresses, which will change if the card is moved to a
different slot or the USB tuner is plugged into a different USB port.
I would only want to use those to differentiate devices if I was
desperate for a way to do it, which fortunately I am not.
