USB Mass Storage devices aren't handled via the MTD driver, generally.
They are handled by the usb-storage driver via SCSI emulation.

If the device shows up in /proc/bus/usb/devices with class code 8, then the
USB low-level is working and it's time to move on to enabling the
usb-storage driver.

The place for usb-storage help is linux-usb-users@lists.sf.net
