/System/Library/Image Capture/TWAIN Data Sources is the old location  
for TWAIN data sources. It is still in the search path of the system  
for backward compatibility, but the preferred location is /Library/ 
Image Capture/TWAIN Data Sources. If you have installed the TWAIN  
SANE Interface this is where you should look for it.

The vendor and product IDs in the Info.plist file are only important  
if you are using Image Capture (or any other program that uses the  
TWAINBridge application to interface to the scanner). Programs that  
use TWAIN directly works anyway. This is the end of my Info.plist  
file where I have added the USB IDs for my mouse to trick the  
TWAINBridge application that there is a scanner attached, since it  
doesn't detect my SCSI scanner.
