Using windows XP.
I have been using a Sanyo 3-pedal foot pedal, with usb connector, to listen to voice dictations using Express Scribe. I started receiving digital voice dictations using a different playing software and my sanyo pedal would not work. I have to use an Infinity 3-pedal foot pedal, with usb connector, to listen to those non-Express Scribe dictations.
When a voice message comes in to Express Scribe, I have to plug in the Sanyo pedal. When a voice message comes in which is not Express Scribe, I have to unplug the Sanyo and plug in the Infinity pedal.

Why can't one 3-pedal foot pedal enable me to listen to both? Better still, is there a way that I can get either one of these pedals to listen to both types of voice dictations?
