thanks for the response. i found the cause to be the epson2 backend. i 
amended the dll.conf file to use the epson backend instead and now the 
scanner is listed via scanimage -L.

i'm now having problems making the scanner available to non root users 
permanently as fc9 appears to have changed from using udev to hal (see in fc8 i simply 
amended /etc/udev/rules.d/60-libsane.rules but this isn't available in fc9.

i can chmod 666 the device file but this doesn't survive a reboot.
