Product DescriptionThe DUB-C2 is a Hi-Speed USB 2.0 2-port CardBus adapter that upgrades notebook computers to the new and faster USB standard. This card is designed to work with mice, keyboards, external CD-R/RW's, external hard drives, PC cameras, and all other USB enabled devices. It is 40 times faster than previous USB adapters and 20% faster than Firewire (IEEE-1394). Each of the two USB 2.0 ports transfers data at 480Mbps (Megabits per second), making it ideal for external storage, backup, networking and digital video.The DUB-C2 is compatible with USB 2.0 standards and is backward compatible with USB 1.0 and USB 1.1 products. This gives you the ability to connect all of your USB 1.x devices to the DUB-C2 USB 2.0 adapter and they will work. Each port detects whether the connected device is USB 1.x or USB 2.0 and automatically runs the device at the correct speed. The DUB-C2 supports Plug-and-Play installation which makes the DUB-C2 easy to install.

Rating: - crappy performance, beware two product versions
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. I've had several corrupted hard drives from trying to use it with a USB2-IDE adapter cable under XP, and on OS X 'Tiger' on my G3 Powerbook, it causes ... Read More

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. ... Read More

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. It usually turns off abruptly during the Windows ... Read More

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. Now my friend's card came to him in good shape, but mine arrived with the plastic casing not even closed around the ports. In fact, I couldn't ... Read More
Rating: - Slower than UBS 1.0 on my Sony PCG-FXA32 Laptop (XP)
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. ...
