DUB-A2: Introduction
The problem with your screamin' hot rod computer from two years ago is that it more than likely does not have any Hi-Speed USB 2.0 support. D-Link offers an option to get around this potential snag with its add-on PCI Adapter card. This Hi-Speed USB 2.0 PCI Adapter card features two ports that can transfer data at the USB 2.0 standard speed of 480 Mbps (Megabits per second). This card is designed to work with every USB 1.1 and USB 2.0 device ever made, including mice, keyboards, external CD-R/RWs, external hard drives, PC cameras and Ethernet adapters.
We are assuming that this USB 2.0 PCI Adapter card offers only two ports in order to keep its cost lower. The USB 2.0 card itself features a USB 2.0 chipset from VIA. The average retail price online is $25 US. Other manufactures offer PCI cards that have four or five ports, with some internal ports as well. Do not let the fact that this card only has two ports deter you from considering it for purchase. Twenty-five dollars is a small price to pay for the ability to transfer data at 480 Mbps. You can always attach a USB hub if you need more ports, but for getting your new USB 2.0 CD or DVD writer online, this will fill the bill perfectly.
The DUB-A2 is certified to USB 2.0 standards and is backward compatible with USB 1.x products. Its backward compatibility allows all of your USB 1.x devices to work when connected to the DUB-A2. Each port detects whether the connected device is USB 1.x or USB 2.0, and automatically runs the device at the correct speed. Installation of the DUB-A2 is as easy as installing any "Plug and Play" device.
