You should see the folowing if you do "ls -al /dev/pt_drv"
crw-rw-r- 1 <owner> <group> 40, 0 <date> /dev/pt_drv
If it doesn't exist you need to create it with "make install" and
"make load" in the plustek_driver directory. You probably have to
be root to do this and unless you are using something like sudo
you need to be root to "insmod pt_drv"
