USB not recognizing

Hello. Hoping somebody can help. I was cutting yesterday morning with no issues. I shut down and unplugged the USB. I went back a few hours later and now I get a message that it doesn’t recognize the USB. I did verify that the USB port is working on my machine. I also uninstalled and reinstalled Mach to see if it would recognize the controller. I also verified that I had the controller in the plug ins etc. I do have power to the box. I can hear buzzing.

i do have a pic of it if you would like to see.

Suggestions on what else to look at? Appreciate it!

Derrick what machine do you have and how old is it? Your profile says CF Pro but you’re talking about Mach?

What operating system and version is on the computer that is connected?
