It was working fine and well but I tried connecting it to a USB cable that only had power and ground cables in it the data cables were removed. this was to test another problem that isn't relevant to this. after this it won't show up on any port or in the device manager. I don't think it's even trying to communicate over USB now but I'm very unsure. it's an Uno wifi r2
plz help, I'm doing Mark Robers engineering course and need it to work for that.
