Problem:
The following error message appeared: "Error: Not Enough Power to
Function"
Solution:
The Macintosh OS generates this message if:
A device draws too much power from the USB bus
One or more devices plugged into a hub require more power than is
available
You attached a self-powered device (such as a printer or floppy drive) to
your computer without plugging it into an electrical outlet.
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
scanner extension is loaded and on.
Problem:
The following error message appeared: "Scanner not found" or "Unable to
control scanner"
Solution:
Follow this procedure:
1. Confirm the scanner is plugged into the computer's USB port.
2. Go to the Apple System Profiler, listed under the Apple menu.
