libusb on FC2

[Cyber Source]

I just had this EXACT problem. In fact I had a scanner that I had to 
download a new sane backend for and it actually worked! The trick to get 
past the need for root with that scanner and libusb was to put the 
following line in your fstab file,
"none /proc/bus/usb usbfs defaults,devmode=0666  0  0", without the 
quotes of course.
