I read this bug description by Intel, and the sentence that decided me
to buy a USB2 soundcard is this:
"High-Speed and Low-Speed USB devices are not impacted by this issue."
I actually have an Edirol UA-25Ex that plainly doeson't work on these
USB ports, so I went for the M-Audio USB2 High-Speed hoping that would
solve the problem!
