I'm not sure, I disabled Windows updates long ago. Unless there are still some things being updated in the background without me knowing?
Anyway one day the pedal just started disconnecting randomly, not sure why. I have been using the new pedal that I bought recently daily and I have not had a single issue with it yet, so my guess is that it's something to do with the Infinity pedal.
If you don't want to buy a new pedal, maybe try remapping the buttons in Express Scribe. For instance use the right button for play/pause and left button for rewind. I have a feeling the problem could be with the middle button (I assume you use it for play/pause, if not, my appologies). I have NOT tried this myself, it's just a thought I had after my new pedal got delivered, I have no idea if it's going to work, but might be worth a shot.
