That's a good idea to do a diff - I was manually looking at the two files.
But unfortunately the only difference seems to be in ATTRS{urbnum} - which
get changed with every boot up.  I wish I could force udev to make them
adapter0 and adapter1, rather than adapter1 and adapter3 - especially since
I now have no adapter0 and adapter2.

Oh well ... at least I've learnt how to use udev!
