Which kind of USB2 card?  What is the chip on it?  I wonder if you have
a defective card, or a card with a badly behaved chip.  Or maybe you
you have it on the same irq as something which doesn't like sharing (USB
should never mind sharing, but some other devices are not as well
designed).  Does the card share an irq with another device in the
system?
