Abstract
A network device includes Power-over-Ethernet PoE ports to communicate with a communication network and Universal Serial Bus (USB) devices. The network device establishes an Internet Protocol (IP) related connection with an application program, and receives downlink IP packets carrying USB transaction requests destined for the USB device from the application program over the IP connection. The network device converts the received downlink IP packets carrying the USB transaction requests to downlink bus-level USB transactions that are understandable to the USB device. The network device sends the downlink bus-level USB transactions to the USB adaptor device over a PoE connection for forwarding by the USB adaptor device to the USB device.
