I have an Epson 1260 USB scanner.

I am running Woody, with the latest Sane backport from 

Under both root and my own user account, sane-find-scanner returns:

found USB scanner (vendor=0x04b8, product=0x011d, chip=LM983x?) at 

Under root, scanimage --list-devices gives

device `plustek:libusb:002:003' is a Epson Perfection 1260/Photo USB 
flatbed scanner
... and I can actually scan a page using scanimage -d 
plustek:libusb:002:003 --format pnm >outfile.pnm

But, under my own user account, scanimage --list-devices gives

scanimage: no SANE devices found

Obviously there is a permission problem of some kind. 

However, my own user account is a member of "video" and "scanner".

The entries in /dev/usb are members of group "video" and have -rw-rw-rw 

I'm not sure if it is relevant, but on boot I get the messages 
(0x4b8/0x11d is the Epson 1260):

usb.c: registered new driver usbscanner
scanner.c: 0.4.6:USB Scanner Driver
usb.c: USB device 3 (vend/prod 0x4b8/0x11d) is not claimed by any active 
scanner.c: open_scanner(0): Unable to access minor data
