I have the U3818DW 38" USB-C monitor. I can't believe I am the only one having this issue. I am using this monitor with 2016 touch bar macbook pro. USB-C works great. Charged my mac and also drives the monitor. However, all the USB ports in the monitor ONLY work at USB-2 speed. I even tried the USB Upstream cables to see they help. So. How to get the USB ports to work at USB-3 speed when connected to USB-C?
