I order a BF-810 prolific usb to serial port converter and i cant get it to work. I have talked with the suppliers and they have no idea. I am using windows xp and my laptop has no serial ports so i bought the converter. I installed the device and updated the drivers. It shows up in my device manager as comport 4. Under properties though i noticed it doesnt have a resource tab. Anyways I tried using Hyperterminal and other programs to open a connection and nothing works. I was wondering if anyones else has dealt with usb conversion and how to solve this?
