UNIVERSAL SERIAL BUS BRIDGE

摘要

A USB controller is for use in an electronic device, and has two ports. A first port acts as a device port, allowing the electronic device to be connected to a host device. A second port acts as a host port, allowing the electronic device to be connected to a peripheral device. When a host device is connected to the first port and a peripheral device is connected to the second port, the peripheral device can be shared simultaneously between the electronic device and the host device.
