I am far from an expert in this area, but I am successfully using a USB smartmedia reader on a system that also has SCSI discs. I have the disc wired down: # SCSI Controllers device sym0 # NCR/Symbios Logic (newer chipsets) # SCSI peripherals device scbus # SCSI bus (required) device da # Direct Access (disks) device sa # Sequential Access (tape etc) device cd # CD device pass # Passthrough device (direct SCSI access) # Wire down the boot disc to avoid being usurped by USB peripherals! device scbus0 at sym0 device da0 at scbus0 target 0 unit 0 If your camera has the usual formatting for smartmedia or compact-flash, it will have an fdisk table and a DOS filesystem in the first slice, so you want something like: mount -t msdos /dev/da1s1 /mnt to mount it when the drive has popped up at da1.
