Abstract
A Network-Universal Serial Bus (NUSB) adaptor exchanges Power-over-Ethernet (PoE) packets with, and receives power from, a Power Source Equipment (PSE) over a PoE connection with the PSE, and exchanges Universal Serial Bus (USB) messages with, and provides power to, a USB device over a USB connection with the USB device. The NUSB adaptor converts between a USB power negotiation protocol implemented between the USB device and the NUSB adaptor and a PoE power negotiation protocol implemented between the NUSB adapter and the network device.
