Add USB 3.0 ports and Gigabit Ethernet to your computer

Kanex says their DualRole is a “perfect companion for laptop users who need additional USB 3.0 ports for instant connection to peripherals and to connect to a secure wired network using Gigabit Ethernet simultaneously.”  It's especially useful for those who have the tiny laptops (Windows or Mac) that sacrifice the number of USB ports for a smaller size.  If your USB devices need extra power, you can add a power supply to the DualRole.  It offers hot-swappable plug-and-play ports, and it is “compliant with Universal Serial Bus Specification Ver. 3.0 (Data Rate 5Gbps)”.
