USB-C hub: unable to detect any network interface

[watain]

I have a no-name USB-C hub with a rj45 interface which I can't seem to detect. Everything else from the hub works fine (power, HDMI, USB, card reader).
I have tried to load a bunch of different drivers, without success.

Any ideas what to try?

watain,

that you have a selection of USB2 and USB3 root hubs.

USB-C should be USB3 with added capabilities.

However ...

The root hub your USB-C hub is connected to is being forced into USB2 mode. That's a bad thing.

Exactly how is your USB-C hub connected?
If its connected to a USB-C port on your PC, do you have USB-C support in your kernel?

If its using a USB-A to C converter. Many of them are intended to charge USB-C devices only, so they only have the USB2 data pins connected.
If its a USB-A to C converter that supports USB3, the USB-C connector often needs to be connected the right way round for USB 3 to work.
That is, only one set of USB3 pins are connected but USB-C is reversable by design.

My USB-C hub connected over USB-C shows

Oh dear ... putting usb 214b:7250 into startpage.com says that the Vendor and Device ID belong to a USB2 device.
Still, the network port should work at 100MHz and even with no driver installed. the network port should appear in lsusb.
