FreeBSD usually uses /dev/uscanner0  as a device node for scanners (and 
driver uscanner)unless you are using HPLIP driver.
It is true though that in OpenBSD some scanners has to be seen as 
/dev/ugen0 since uscanner driver for OpenBSD
does not support receiving vendor name and product.

Are you sure you have right permissions? Also for plustek backend you 
have to add your-self into _saned group.
Did you reboot (I hope not server:-)))) the thing after you plug the scanner

What is the output of sane-find-scanner ? Which version of SANE-backends 
do you have. They came up 2 weeks ago with 1.19 release which I use on 
4.3 beta OpenBSD but on my FreeBSD machines the version is 1.17.

Did you check if the scanner is listed in the sane data base.
