Remove all other devices from the USB chain, so the scanner is the only device on the USB chain. Make
sure that the scanner power adapter is plugged directly into the wall, not into a power strip.
Problem:
The following error message appeared: “Error: No Driver Found”.
Solution:
The Macintosh OS generates this message if it could not find a driver in the System Folder for the USB
device you just connected. You may have forgotten to install the software that came with the device, or
you may have put the device driver (i.e., the software that allows Macintosh to recognize and communicate
with the USB device) in the wrong place in your System Folder.
Re-install the software driver from the VistaScan CD-ROM. Make sure the extension is loaded and on.
Problem:
The following error message appeared: “Scanner not found” or “Unable to control scanner”.

3. Go to the Devices & Volumes tab (C 2). Verify the scanner is listed under the USB tree as:
