thanks for the suggestion, but the camera was a red herring.
it was actually the usb key that i'd plugged in.  the key works fine
with xp.  so i engineered a swap of usb keys.  it was dying in
setup0 with Estalled.

shouldn't usbd be resistant to badly-behaving devices?
it seems that any error on any endpoint will topple usbd,
at least during configure.

one final question, is there an advantage to usb/disk creating a fs
that's incompatable with devsd?  it would seem to make booting
from usb root difficult.
