Bad Prop Plug E?

I purchased a Prop Plug E a week ago and was using it with the Edge bread board with no problems. I unplugged from the computer then plugged it back in and got a unrecognized usb device error.

I tried installing the Dell authorized FTDI driver and it did show a usb comm port in the hardware manager but when I unplugged it then plugged it back in I got the error again.

I then used the CDM uninstaller to remove all FTDI devices. I then plugged in my old Demo board without installing any ftdi drivers and it found a comm port in the Hardware Manager but when I put the Prop Plug back in I got the error again. I'm using Windows 11 24H2.

Also while I was using it I had one of those cheap china usb logic scopes running Logic 2.

Has it gone bad or is there some conflict with the driver?
