D6000 on USB-c Issues

[zocoloni]

Hi,
this is my current setup:
- Ultrabook HP Spectre X360
- Dell ST2410 (available ports: VGA, DVI, HDMI)
- Dell U2312HM (available ports: VGA, DVI, DisplayPort)
- I am using the latest DisplayLink drivers and latest drivers for my laptop USB ports.

I bought the docking station DELL D6000 (as listed by the Products page in the DisplayLink website) in order to attach both monitors at the same time as well as to charge my laptop). The problem I am having happens when i try to connect the dock to the laptop using the USB-C connector.

Using USB-C: I connect the dock to my Thunderbolt 3 USB-C port
1st Display I connect with an HDMI-->HDMI (This monitor works)
2nd Display I connect using a DisplayPort --> DisplayPort (THIS DOES NOT WORK)
I tried using a different adapter such as DisplayPort --> DVI but that didn't work either on the second display. In short, I tried to connect my setup in many different configurations but it always comes down to the DisplayPorts on the dock NOT WORKING while in USB-C mode.


Using USB 3.0: I connect the dock to my USB 3.0 port
1st Display I connect with an HDMI-->HDMI (on the dock)
2nd Display I connect using a DisplayPort --> DisplayPort.

This second setup works like a charm with both displays running at HD (1080p) resolution but the only thing missing is that my laptop doesn't charge using the USB-3.0 port so i have to switch back to USB-C every couple of hours.

Can you please help me identify the issue and solve it?
