Topic: USB Port Hardware Incompatibility

On some computers, the card scanner may encounter a hardware incompatibility with the USB port of the computer.

The possible indications of a hardware incompatibility are:
a. The scanner does not work even though the Device Manager in the Control Panel indicates that the scanner is installed and working properly.
b. The scanner works only intermittently.
c. The scanner will not calibrate, or the calibration card does not move through the scanner during calibration.
d. The system hangs during calibration or scanning.

e. The scanned image is blank (or black) even after scanner calibration has been performed.

 

How to verify USB Port Incompatibility

1. If the scanner was previously working on the computer and after some use has suddenly stopped working, then it is likely that the scanner itself is faulty, and it is not a compatibility issue. Please contact customer service about repair/replacement options.:

 

2. You should try installing the scanner on a different computer to verify if it is a working unit. If it does not work on another PC, then it is likely a faulty scanner, and not a USB compatibility problem.

Solution:
The best solution to a USB port hardware incompatibility is to use an external (multi-port) USB hub.

1. Purchase an off-the-shelf standard External Multi-Port USB hub. A simple low-cost unit will do.
2. Plug the external hub into the USB port of your computer.
3. Plug the card scanner into one of the available USB ports on the external hub. Do no plug any other devices except the scanner into the external hub.
4. Install the scanner driver if prompted by the system.
