I have a Badaax UM600 usb mic. I have been trying to get it to work. I was completely unable to use it on win7 and I just upgraded to win 8.1 Pro. I was able to use it perfectly fine with Audacity. Six hours later, I tried to use it again, and the computer would not even recognize that anything was connected to the USB ports. I tried both ports, unplugging and replugging it back in. I have tried to troubleshoot it, and windows says the drivers weren't installed properly. I followed troubleshooting steps, and that came up with a failure to install properly. I can't figure out what is wrong. Any ideas would be greatly appreciated
