Well, I even used a newly formatted clean partition and it did not work, on which I installed a "virgin" copy of first 10.5, then went back to 10.4. At this time not even with a clean install of 10.4, under which it ran flawlessly until installation of 10.5, will let it access. What stuns me ist that it will run on the Powerbook G4. Also, another scanner attached will work.
I had just recleaned the partition, installed 10.4, the latest version of Epson software.... just won't work. Image capture does see the scanner, but will not connect. Another observation: photoshop elements will not install on the machine, but will boot over a network connection from my powerbook. weird..... trying to install will render the error file missing: postflight script, whatever that is.
BTW Vuescan and Silverfast will not get it either. I connected the scanner to different usb port, checked its functionality on other machines. I have no clue whatsoever why these two objects: 3170 and PSE 4 would not funtion anymore. There were a few of the usual minor glitches on other programs, but nothing to cause concern, the usual little bits while upgrading. Considering my problems with Magicmovie 08, this is my very worst year with Apple since the old Apple II days....
