Hi,
I am using tumbleweed on a DELL XPS 15 9550 (core i7) and trying to connect a thunderbolt 3 docking station (i-tec TB3TRIPLEDOCKPD).
I had no issues to connect a monitor via the dock (hdmi) but I have not been able to use th usb-ports. Here is part of dmesg output indicating trouble with usb (last 6 lines):

I am not sure whether the i915 error messages are related to this problem, possibly not.
Moreover, I have updated the laptop’s BIOS and set the security level within the BIOS TB3 setting to “no security” - this did not solve the problem though.
Thanks for any suggestions!
