ABSTRACT:
A CD-R drive has two USB ports. One USB port is connected as an ordinary interface port to a host computer by a USB cable, and the other USB port is connected as an assist power supply port to the host computer by another USB cable. With this arrangement, the CD-R drive can operate with maximum current consumption of 1.0 A without using a separate AC power supply adapter because each USB port allows passage of 500 mA of current at maximum.
