Hello Michaelgraf1999. Yes, I have just connected everything possible. HDMI, 1x USB external HD, 1x USB stick, 1x USB-Lightning cable (for iPhone), network cable, 1x SD card, 1x microSD and finally even another iPhone on the USB-C... but don't copy that. I had my iPad connected to the USB 3.1A and my iPhone to the USB-C... not good at all... Network connection was also gone afterwards.
