ADB Device not found

Question

I have a weird problem with my adb. I have a Vuzix M300 and a couple of android phones. The thing is after starting to use my Vuzix M300, my android phones are not being detected by my ADB although my Vuzix is now being detected. This was not the case before using vuzix. Before Vuzix my android phones were being detected normally, now its not being detected and only Vuzix is now being detected. What's the problem here?
