USB card readers are handled by the generic mass storage driver, and if I understand the spec correctly, it's the device's job to declare itself write protected and to ignore all attempts to change this state (WP flag in the mode parameter header), so I doubt the driver offers a facility to do this - and you'd still need a card reader with a firmware that violates the spec.
