To be more clear, I am writing a source code so that my board can determine whether any kind of USB is plugged in this USB port. For example, when a USB is plugged in, the LED will turns green indicating that USB is present. If the USB is unplugged, the LED will turn red. | |

In any case you'll have to work from a usb device and trace back up where they are connected to (I'm not familiar with usb-c specifically but if it just draws current without being seen as a device it may make things much harder) . If you want to use an event-based approach the best place to hook yourself to is udevd, and walk up DEVPATH (on bootup the event would still be triggered as the usb devices are added). | |
