Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm concerned about your obviously thoughtfully put question.If the USB error message persists, I have to question whether something has been overlooked.
- How did the cutting of the ground wire (out of the 4 in the USB cable) occur?
- Have you check the USB port on the computer, to make sure it is not dirty/dusty/occluded? one of the four active terminals in any USB port being dirty, can make the port inoperative.
