D Link DUB A2 USB adapter PCI Hi Speed USB 2 ports

The DUB A2 USB card adds two USB 2.0 ports to your PC. If your PC doesn39t have USB 2.0 ports, simply plug it into a PCI expansion slot inside your PC, and you39ll have two super fast USB 2.0 ports. The new USB specification gives you transmission at up to 480Mbps. That39s about 40 times faster than USB 1.1, the earlier USB specification.Up to 480Mbps Transmission Many USB 2.0 products are now beginning to be out in the market, so you39ll need this card to get fast connection. The two ports provided let you plug to USB supported devices and USB hubs. The card supports low speed 1.5Mbps devices, full speed 12Mbps devices and high speed 480Mbps. Each port on the card creates a bridge between the attached USB peripheral or USB hub and the host computer.Backward Compatible Each of the two ports transfers data at up to 480 Mbps. Both ports are backwards compatible with USB 1.1, so you can use all of your older USB devices as well as the new USB 2.0 products. Plug and Play Installation As a standard USB host controller, the card directly interfaces between the USB bus and the operating system. It is automatically configured by the O.S. and operates in accordance with EHCI specification. 39
