We have a customer that has a C5501 and they want an external keyboard on the device. They need this so it is easier to type than using the qwerty keyboard. However, when it is plugged up it gives "Incompatible USB Device". On the 02 models (4502, 5502) there is a service mode (SP-50-75) that needs to be turned on for External Keyboard but this is not there for the 01 models.
Any suggestions?
