It isn't too difficult to replace the sane-backends version that comes Centos 6 with this updated version from Fedora 16.
I have re-compiled SANE-BACKENDS-1.0.22-6.FC16.SRC.RPM for Centos 6/x86_64.
You can also download SANE-BACKENDS-1.0.22-6.FC16.SRC.RPM from this webpage but you will need that only if you want to compile your own SANE-BACKENDS-1.0.22.
After downloading the above files you can install them on your Centos 6 machine using this command: rpm -U sane-backends-*.rpm
That's all there is to it. After installing SANE-BACKENDS-1.0.22, when you run scanimage -L you will see this output:
If you find that scanimage -L sees the scanner when you run the command as root but not when you run the command as a user, then unplug the scanner from your computer and plug it back in. There is a udev rule that allows your scanner to be seen by the user but it's not activated only when you plug the scanner in; therefore if you plugged your scanner in before updating to SANE-BACKENDS-1.0.22 as described in this article, only the root user can use the scanner until you either reboot your computer or unplug the scanner and plug it back in again.
