It looks like a BIOS glitch, though I think that NetBSD should have
handled it better.

I tried the same flash drive under Windows.  I got a pop-up telling me
that it would work better on a high-speed port.  Huh?  It *is* a
high-speed port.  After not seeing any BIOS options, I reset all of my
options to default.  Suddenly, it worked, under Windows and NetBSD.
Should NetBSD have tried a different initialization strategy, for a
lower-speed USB port?

But that's not the end of the story, and NetBSD may be doing something
worse.  For fun, I suspended the machine, then tried using the drive.  I'm
back to the "reset failed" messages.  I don't know if it's significant or
not, but someplace in the suspend/resume process, the following console
message appeared:

	ehci0: BIOS has given up ownership

what does that mean?  Could it be related to my problem?
