It could just be a low quality USB cable that is too high resistance and cannot pass enough power. Try a short, thick cable rather than a long thin one.
Types advertised for use with external hard drives are best for high current devices.Or, the socket may have been damaged when the cable got broken.
In that case, it need a new USB socket installing in the amp.
