Whatever.  What is useful and what is not is very subjective.  It has been
useful for me when I was debugging the plx9052 driver, but I had to be
very careful to unload drivers in a certain order.  Fortunately, it's
fixed now.

I've heard that Orinoco USB adapters consist of a PCMCIA-to-USB bridge and
a PCMCIA card.  I don't know about USB Compact Flash readers.  Such
devices may have very limited (if any) support for unapproved cards, but
it's better to be prepared.
