Ok, minus 10 points for me for not realizing that USB 2.0 devices
were backward compatible with USB 1.x controllers/hubs. ASIX appears
to have a USB 1.x version of this chip as well (Ax88170) with the
same programming API.

Of course, I don't actually have any of these pieces of hardware myself.
I guess I could stop by CompUSA on the way home tonight...

Now look what you went and started.
