   sg3_utils includes sg_scan -i which will identify all SCSI including
USB devices (not any hubs or controllers) with their /dev/ identify.
Usually thumb drives and camera flash memory cards (in readers or in cameras)
wind up being /dev/sg1 through /dev/sg4 the drivers (modules) are necessary,
as others mentioned.
