Connect USB C to Controller Port on 2600+

Looking for a device that I can use to connect a micro controller that uses usb c straight to the controller port on a 2600+. All searches seem to be for for computers, which is not what im looking for. I have found some cables on Amazon but read that serial connections likely won't work as anticipated. Is there a search query I should be using? suggestions for this type of adapter and/or cable?
