I'm trying to do some reprogramming of my 396XT via the new Windows 8 machine, and it seems as if there's some type of disconnect between the scanner and the laptop. Here's the error message that comes up when I enter into communications setup: Software has not detected your scanner, please check scanner is switched ON and connected. Read instructions how to setup scanner communication.. Well, the scanner is obviously on and I'm using the USB cable that I purchased from scannermaster. I've also installed the Prolific PL2303 driver. What else am I missing? I never had this issue on my Vista machines...
