Already tried the Surface USB-C to ethernet and USB 3.0 adapter which works fine.
Today also tested Cable Matters USB-C Multiport Adapter with 8K DisplayPort and PD. Everything seems to work: DisplayPort with external screen, fast ethernet, USB connected to an USB memory stick, USB connected to Startech USB Switch which is connected to my Microsoft Lifecam Cinema webcam and also is connected to my USB-hub on my external screen. On this USB hub on my external screen my wireless adapters for mouse and Logitech MX Keys keyboard are connected. Everything is working! Rather fun and also very easy to work this way.
Only thing not working is PD (power delivery): when connecting the power adapter to the Cable Matters Adapter the external screen seems to disconnect. This is too bad, because when connected to this set-up battery is going empty very fast.
Anybody knows why Power Delivery is not working?
