usb-c ports just show up as USB ports. usb-c is a physical connector, not a signalling protocol: the signalling protocol is USB. There is no logic difference or application difference between using a USB-C port or a USB-A port.

If the device is not showing up in Device Manager then you have one of several possibilities:
  • the usb-c port is broken.Try a different device and see if the other device shows up
  • the usb-c cable is broken
  • the device expects to receive power from the usb-c port but you are not providing enough power for it (especially if you are using a hub). This does depend upon the USB port type as usb-c is rated for higher power than usb-a or usb-b (micro-USB)
  • the device is broken. This does not depend upon the USB port type
  • the device type was not recognized and no driver was found for it. In such a case normally the Device Manager would list the device, just possibly with numeric codes that you did not recognize. This situation does not depend upon the fact that you used usb-c, as this level depends on the manufacturer and device type codes that were signalled as data, with the port type not being relevant
