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. - erik
