Same problem here. My pedal works with DocQScribe, but not using Express Scribe. I have tried it on both my PC running Windows XP and my laptop running Windows Vista. I get the same error message with both computers that indicates that there is not a Vec USB Foot Pedal attached or it is not a Vec foot pedal. Which of course it is a VEC pedal and it is attached. I have tried installing the Vecusb file as a stand alone download, but that did not resolve the issue. Does anyone have any suggestions to resolve this issue?
