Hi, Currently, I am using the two USB-3 ports for wireless keyboard and WiFi dongle because I have not been able to get the antennas attached to my m.2 WiFi/BT card yet. Anyway, I need at least one more USB port but have not been able to get either of the USB-C ports to work. Is there some trick to this? How do I do this until I can get a USB-3 hub? 8-Dale
