  • Method and apparatus for communication between universal serial bus (USB) host and USB device
    Patent number: 8117365
    Abstract: A method of interfacing between a universal serial bus (USB) host and a USB device. The USB host and the USB device include modules to process packets according to network protocols, instead of USB bus interfaces. Therefore, the USB device can be connected to the USB host even without a USB cable, and thus is not affected by the distance between the USB host and USB device.
