Summary: I bought one of these about a year ago. Note that there were two versions of the DUB-C2 made, and the revision A1 was more or less abandoned by D-Link with horrible drivers and very poor compatibility. The revision A2, however, is still supported with drivers as recent as May 2005. Make sure of what you're getting. I have an A1 model.
Summary: This D-Link DUB-C2 cardbus adapter for USB2 but caused so many problems I gave up on it. Hours with D-Link support but card never produced USB2 speeds. I bought an ADS Tech Dual-Link cardbus adapter DLX-181 that arrived today. Nice card: two USB2 ports (one powered via adapter, one unpowered), one firewire 6-pin and one firewire 4-pin ports. Most support and forum gurus say not to install the proprietary drivers but to let W2K with SP4 find and install its own drivers.
Summary: This card has worked flawlessly on at least two of my friends' computers, a top-of-the-line ThinkPad and a Dell Inspiron 4000. Alas, it's a different story on mine. I have an HP omnibook 500, and when I first plugged this thing in, the machine instantly turned off, as if I had reset it. I think it screwed up my COM2 port, too. Now, when I want to use it, I have to shut down to put it in, then reset my machine, turn it on, and pray.
Summary: Upon seeing the last few gigabytes of our laptops' hard drives dwindling down, my friend and I invested in external Iomega USB 2.0 120GB hard drives. Our computers were only USB 1.1, so we decided to look for an option to allow ourselves the speed of USB 2. The D-link DUBC2 was the cheapest and simplest solution, and for about 30 dollars we both purchased one.
Slower than UBS 1.0 on my Sony PCG-FXA32 Laptop (XP)

21 May 2003
Summary: 1. Windows XP had difficulties to validate the drivers that came with the cd-rom. 2. After installed the drivers, the transfer rate between the Sony laptop and a USB2 external cd-rom was many times slower than the USB 1.0 port. ...
Summary: Try to install it on my Compaq EVO N600c laptop running Win 2000 professional and keep crashing. Called Tech Support wait for 30 minutes and was told BIOS need to update BIOS before it will work. Ask what BIOS and version it will support and was told that thet did not know and I should contact Compaq. Updated BIOS from Compaq and still does not work. Returned product and will not deal with DLINK again.
Summary: This card installed without a hitch on my Windows XP Home Gateway laptop. Installed the driver from the CD, turned off the system, inserted card, powered back on, and the two high-speed USB ports were ready to use. Note that there's no external power jack on this card, like some USB 2.0 pcmcia interfaces have - so some users might have problems using devices that need to draw substantial power from the port.
