Scanner Problems

[Peter]

I use different laptops for separate functions. Each requires documents 
to be scanned. I plug the usb scanners into whichever laptop I am using. 
there was no problem until Friday.  I have found that one of my laptops 
which had not been used for a few months still works with the scanners. 
The others which get updated on a regular basis do not.
