USB C hub and Ethernet adapter
#1
Hello,

I have a Pinebook Pro, and I'd like to connect it to a hard wired network.

I have 2 different USB-C hubs that I could use, and here's a link to them on Amazon:

1. https://www.amazon.com/gp/product/B07TVSLDND/
2. https://www.amazon.com/gp/product/B07QJXP3DV/

I've tried both, and while it seems that USB ports on these devices work, the ethernet ports don't seem to work or show in `ip a` or `ifconfig`.

How do I get the ethernet port to work or 1 or both of these devices?

What distribution are you using?  and, have you tried plugging in the device "upside down",  that is oposite the cable orientation you are currently using.  A number of people have noted that some of the devices  work only if they are plugged in in a particular  orientation,  although that is not SUPPOSED to matter with a usbc cable.    I have one such device..  https://www.amazon.com/gp/product/B07Z7H3GJK  I am  using Manjaro.

I'm not sure what the distribution is called. It's Debian derived, and it was what was pre-installed on the Pinebook Pro.

Plugging the hub in upside down seems to do the same thing as plugging it in as I had it.

A tail of `/var/log/syslog`seems to give messages regarding the xhci-hcd USB driver when I plug it in. It also says something about `device not accepting address 4, error -71`.

I really don't need the USB, VGA, or HDMI on this hub; I just want the ethernet port and the charge by USB-C capabilities. The charging works, the USB seems to work. The ethernet doesn't.

If you are sure that these have working ethernet by tring them on another computer, I would try another distribution. Just use an sd card version of perhaps Manjaro,  (not one that installs to emmc,  just one that installs and runs on SD) --or any distribution that uses a newer kernel.   It is possible that various drivers have changed.  I have used the hub I mentioned,  as well as another  old anker usb 3 ethernet adapter and both have worked. 

If my device is installed on the PBP but not connected to the etherneti I will see etho with ip a as down,  and it will show as UP when it is connected.   

I suggest using a distribution with a new kernel in case you are seeing some kind of driver or other software issue.
