Neither upgrading the BIOS nor fiddling with USB settings had any effect.
I'm currently running 2.6.22 and built a 2.6.23 to check.  That didn't
work.  On a lark, I tried older kernels.  Those didn't work.

Here's a rather annoying quirk about USB that I have become painfully
aware of lately.  USB cards that include internally-accesable ports almost
always provide them as female type A jacks.  Motherboards on the other
hand always provide internal USB ports as pairs in 5x2 headers.  The only
kind of internally-mounted device I've found that wants to plug into a
type A jack is one specific make and model of hub that fits into a 3.5"
bay.  Everything else like extra ports and card readers all want to plug
into 5x2 headers.  This has led me to acquire a powered minihub and graft
onto it headers and a hard drive power jack.
