I'm running 2.0 on a D845GBV intel board. Regular USB mass storage
devices seem to work just fine on it. I have a "mediagear"-brand USB CF
reader that works fine on linux on the same hardware. But when I plug in
the reader under netbsd2.0, i get:
"uhub1: device problem, disabling port 1"
and nothing else. At this point my other USB mass storage device ceases
to work. I have no other USB devices attached to the machine. Whats
going on?

P.S. Here's my dmesg:
