Further to the caveat emptor, USB2 designations are misleading. Check
for numbers or know the nomenclature before you buy or you risk getting
the slower of the varieties.

Not all of them. MY PQI reader is labelled right on the back "use only
with USB 2.0 Hi-Speed" My desktop just won't acknowledge it when I plug
it in.

I have just the opposite case. Works on my laptop, and my wife's
desktop, but not on mine. Someday I will take HP to task for false and
misleading advertising...

Well, now you do. I have a PQI reader that is clearly labeled "for use
on USB 2.0 Hi-speed interface only", and they mean it, as it won't work
on my desktop machine. Doesn't even see it.

I rather like the reader, and have no real reason to have it work on USB
1.1. My desktop machine has an internal (USB 1.1) reader, so there is
no need for an external reader on that box, and it works fine on my
laptop, which has USB 2.0 Hi-speed.
