ABSTRACT:
A reciprocating plug detector is configured at the connector of a portable device and is pushed to generate a control signal when the portable device is plugged into a host system. A controller of the portable device then performs a command when receiving the control signal. When the portable device is unplugged from the host system, the reciprocating plug detector may also be used for generating the control signal and before the portable device totally leaves the host system, the controller performs other pre-defined command during these few milliseconds. The portable device is implemented with a variety of computer controllability and provided with power-failure protection for data.
