Conclusion
The DUB-A2 High-Speed USB 2.0 Two-Port PCI Adapter card is an economical way to enter the USB 2.0 arena. Installation went without a hitch, thanks to plug and play support and the provided driver CD-ROM. This adapter card will help you out in a pinch if you need help getting your new external CD writer online. You can purchase the DUB-A2 from the D-Link website for only $29 US. The DU-520 features five USB 2.0 ports, with four external ports and one internal port.
The DUB-H4 High-Speed USB 2.0 Four-Port Hub is a good way to divide up the 480 Mbps provided by the USB 2.0 standard. It features four ports to aid you in connecting up to 127 devices to one port!! It can be purchased from the D-Link website for $29 US, or $7.25 US per port. If four ports are not sufficient, D-Link does offer a seven-port hub (DUB-H7) that should keep the cost per port down to less than that of the DUB-H4. Unfortunately, there is no link on the D-Link website to purchase the DUB-H7 directly from D-Link.
THE DUB-E100 Hi-Speed USB 2.0 Fast Ethernet Adapter can give you a true 100 Mbps Full Duplex connection not limited by the USB controller. With the USB 1.1 fast Ethernet adapters, you are limited to 12 Mbps, even if the controller links up at 100 Mb. The DUB-E100 can be purchased for $29 US directly from D-Link's website. This adapter would make a great addition for anyone technically inclined.
At $29 US, these USB 2.0 devices offer a smart way to jump into the USB 2.0 arena.
