It also creates three new additional USB 3.0 hub ports with each port supporting data transfer speeds up to 5 Gbps.This USB 3.0-based NIC lets you connect to your home or office network at full Gigabit speeds with support for 10/100/1000 Mbps. It supports features such as Wake-on-LAN (WoL), VLAN tagging and Jumbo Frames.The U336-U03-GB is backward compatible with USB 2.0 and USB 1.x standards and will support older USB devices.
