I have just bought a PL2303 to talk from my Win 8 PC to a serial device.
The PL2303 installed fine and shows ok in device manager on the Win 8 PC. However when I try to access my Optical Character Recognition (OCR) device over the serial connection I get the following error in the application that comes with my OCR device:
“Communication Port Not Found. Please verify your settings in the option menu”
When I look in the options menu I can see the USB / COm port and it is selected.
When I have used this same OCR device, software and PL2303 on a Windows 7 machine then it all worked fine. So I’m puzzled…
