    摘要: An I/O device powered by its computer interface is interfaced to a computer through a PC Card. A dongle is included with a cable assembly between the PC Card and the I/O device. Power for the I/O device is supplied thereto by an external power supply connected to the dongle. Using a power status input, the PC card can detect whether the external power supply is operational and connected, and accordingly, the PC Card manages operations with the I/O device.
