Traktor s3 + X1

Hello, I just bought an X1mk2 and I want to use it with my S3. Unfortunately my pc (Windows Surface pro 7) has only 2 usb port (1 usb and 1 usb-c), and I’m already using one because I keep my music on an external usb stick. Is there a way to connect the X1 through the S3 (maybe using that usb output labelled iOS) or do I have to buy an usb multi port?

Thanks for your attention
