USB 2.0: High-Speed Devices from D-Link

Package Contents And Connectors/ Indicators

Inside the packaging, you will find the DUB-A2 Hi-Speed USB 2.0 PCI Adapter, an installation guide, a CD-ROM with the necessary drivers and the standard warranty card. Our test unit also contained a six-foot, high-speed USB 2.0 A to B cable, which was not listed on the outside of the box as part of its contents. We don't know why this cable was provided, unless D-Link thinks you need to have a spare A to B cable.

The DUB-A2 does not have any indicators to speak of, but it does have two connectors. And, since it is a two-port USB 2.0 card, both ports are standard Type A connectors for hooking up your external devices.

Installing the DUB-A2 is very straightforward, as it is a "plug and play" device. When powering on the PC after installing the DUB-A2 PCI Adapter card, Windows XP will detect the card and launch the Found New Hardware Wizard (FNHW). Make sure that the DUB-A2 driver CD is in your CD-ROM drive, then select 'Install the Software Automatically' and click on 'Next.' You will get an Error Window that indicates the DUB-A2 has not passed the Windows Logo testing to verify its compatibility with Windows XP; but click on 'Continue Anyway.' The next screen will say 'Setup has finished installing USB 2.0 Setup program on your computer.' Then, click 'Finish.'

Windows 2000 will detect the DUB-A2 after installation and will also launch the FNHW. Again, make sure that the driver CD is in your CD-ROM drive, and click on 'Next.' The next screen will want to know how you want to find the device driver; select 'Search for a suitable driver for my device' and then click on 'Next.' It will read, 'Welcome to the USB 2.0 Setup program'; click on 'Next.' On the 'Locate Driver Files' screen, put a check mark in the box for CD-ROM drives and click on 'Next.' The FNHW will find a driver for the Universal Serial Bus Controller (vusb2.inf); click on 'Next.' Click on 'Finish' when you see the message, 'Completing the Found New Hardware Wizard.'
