Well, came home and plug the USB cable into the computer and started up ProScan and ProScan worked. Sometimes I have to turn the scanner off and back on to get ProScan to run. IDK.
So in real life Proscan starts and loads just did not connect to the scanner.
For whatever reason if the 435 536 SDS100 or SDS200 is powered on when the PC boots the Scanners have to be power cycled to connect to Proscan this is not a Proscan problem it has something to do with these scanners not Proscan.
