My USB suddenly won't connect and after a number of failed attempts to reconnect with software solutions, I suspect the USB port on my CODE 100 Combo is to fault. Are there connection options available via the headphone jack? Are there fix or replace options for the USB port?
First of all, before searching for any other solution check your USB cable - it's definitely the most frequent reason of connection failure.
I would recommend getting the amp looked at by an engineer, and they will be able to confirm if the USB is faulty.
