IOGEAR GIC220U USB Adapter
Strengths: Cheap
Weakness: Causes scanner to fail
I didn't have much luck trying to make this card work with my scanner. It is a Canon Canoscan 5000F USB 2.0 scanner. When I plug in the scanner to the IOGear card, I often get messages from the driver saying that it cannot communicate with the scanner. Sometimes, it appears to work, but when I try to scan a picture, about half way through, I get an error message saying that the driver lost the connection to the scanner, and that I should check that the scanner is still plugged in. Replacing the USB cable did not solve the problem. However, the scanner works fine on another computer which has a different USB 2.0 card. I finally decided to replace the IOGear card with an Adaptec USB2Connect card, and the scanner was worked perfectly ever since.
