I have a Dell Precision 7510 with Windows 10. It has four USB A ports and a USB C port. In Device Manager, how do I determine which one of these Universal Serial Bus controllers is the USB C port?

  • Why do you want to identify which one is the USB Type-C port? – Ramhound Dec 21 '17 at 18:19
  • I want to see what the properties/details are specifically for the USB Type-C port – Marathon55 Dec 21 '17 at 18:21
  • What problem are you trying to solve by knowing that information? Here is a news flash, the accepted answer is flawed, if you connect a USB 2 device to a USB 3.1 Type-C port ( with the appropriate cable) it will negotiate and show up as a ISB 2 device. – Ramhound Dec 21 '17 at 18:32
  • I am hoping to find information about the device that will help me determine what USB standard it supports – Marathon55 Dec 21 '17 at 18:36
  • My research indicates that the Dell Precision 7510 only has USB 3.0 ports which matches the device manger list. Use a tool designed to identify which mode a port is in. – Ramhound Dec 21 '17 at 18:37

In the View menu choose Devices by connection and connect something to the USB-C port.

The new device should show under the correct entry.

Another method is to view Properties > Details for each of the devices in question. Going through the list of properties you may find features and IDs that provide clues regarding the capabilities and nature of each specific device, and you may be able to identify the USB-C port this way too.

  • What if I don't have any USB-C devices? – Marathon55 Dec 21 '17 at 17:29

    Then do it by process of elimination: Connect devices to each of the other ports in turn and determine the one leftover. – music2myear Dec 21 '17 at 17:30
  • I considered that but there are 7 Universal Serial Bus controllers listed and I only have a total of 5 USB ports, so it would only eliminate 4 out of 7. Can any of these Universal Serial Bus controllers be eliminated just by their name? – Marathon55 Dec 21 '17 at 17:34

    The remaining controllers may host internal components. More and more these days USB is being used for internal devices as well as external, so this is not exactly a rare occurrence. However, in Devices by Connection you will see what is connected to these, and so you may still find the correct port through this method of elimination. – music2myear Dec 21 '17 at 18:13

Type-C port is just a connector, there is no special properties for it. It is up to system designer what to route/multiplex to this port, be it an alternative DisplayPort, or Thunderbolt, or audio accessory port, or debug port, or whatever on the top of USB 3.0. The OS will only know if there is a corresponding system controller, but the actual routing should be described in system datasheet.

To determine the port functionality experimentally, you would need to have all corresponding devices physically, Type-C USB device, Type-C DP device/adapter, etc., plug them in one by one, and see the system reaction in Device Manager. This is a "plug-and-play" port, so before a device is plugged in, nobody (besides desingners/datasheets) knows what the port will do.
