libusb on FC2

[Robert F. Stockdale IV]

I just converted my my wife to Linux. However, she needs a scanner and 
the one we had was not supported by sane. I recently bought a Plustek 
UT24 which is supported. After a lot of reading and configuring I can 
finally access it as root and actually scan images. When I try as a non 
root user it complains that no scanner is found. I've set 
/dev/usb/scanner* to root  and group scanner. I've placed all users in 
group scanner with read write permissions. The scanner is set up with 
libusb on Fedora core 2. I'd rather not require my wife to become root 
to use this scanner. Furthermore, I  intend to allow network access to 
this scanner so other users can access it. Does any one have any ideas? 
libusb is suppose to be user space and it does work as root. I'm baffled.
