Hi, as of right now we do not have a guide on how to repair the USB port. Hopefully, in the future there will be a guide for this. If you feel confident and have done research on the device, you can use the first step of any of our guides to open the device exposing all the components and see what you can do to fix the USB port. I advise extreme caution if you do decide to open the device as there are many variables to consider. Those cautions are noted in the first step of all our guides. I hope this helps.
