Hi,
Devices that comply with the USB Mass Storage Class Specification should
work with out any special privileges for the user and should not generate
the error message that was displayed to the user with the camera.
The driver is usbstor.sys which should already be installed on all versions
of Win2k, XP, and Win2k3.
USB RBC class devices are unlikely to work with the current implementation
of usbstor.sys. (I'm simply being a parrot here and don't actually know
anything about USBRBC class devices.)
Does anybody know what the brand and/or model of the camera was? Does
somebody (that is not a member of the local administrator's group) have a
storage device to test on the machine?
Paul

Hm.
I can understand not wanting users to be able to load
user-supplied drivers. I think I had been hoping that
the was some standardized view of USB Storage, in the way
that there appears to be a standard USB HID (Human Interface
Device) interface for keyboards and mice.
I'm nearly certain you can use a USB keyboard without the need to
install extra drivers. It is a shame that USB storage does not
have a similarly simple interface. Maybe I am being misled by
the fact that the user had a USB camera, instead of a USB disk.
