~ I HAVE FOUND A POSSIBLE SOLUTION!! ~
I was using a headset that worked for 2 hours, then suddenly had this happen to it. I was stumped, upset, and MILDLY ANGRY..., but I kept trying.. and low and behold!!
I went to:
Device Manager --> Ports (COM & LPT) --> Communications Port (COM1) AND THERE WAS AN UPDATE FOR IT. I updated it, crossed my fingers, and BAM IT WORKED!! Still waiting a day or two to make sure it's permanent, but hope this helps you too!! :))
