USB ethernet not recognized after reboot

Hardware Support

Hi everyone,

I recently purchased a brand-new laptop together with a USB-C IcyBox docking station with ethernet. After reboot, the IcyBox's USB ethernet is not recognized until I unplug the USB-C cable and plug it back in. As this is quite frustrating, I also tried other docking stations meanwhile, unfortunately with the same result. So I suspect it might be an OS issue.

I use Zorin OS 17.1 Core and already tried the command mentioned here right after reboot, while the ethernet adapter was still unrecognized: Strange issue with USB-C Ethernet cable - #9 by BrewCoffeeAddict

Unfortunately, also with no luck - I still need to unplug the USB-C cable after every reboot.

Here are the details of the USB ethernet adapter in question (taken from the command stated earlier):

Any help is greatly appreciated. Thank you in advance.

Did You looked if there are any Drivers in the Additional Driver Tab in Software & Updates to install?

Hmm ... is on the Manufactorer's Website not any Advice for Linux Usage or maybe a Driver that is needed?

I don't think it's a driver issue, because the ethernet works after I unplug it and plug it back in. It's just that it doesn't get recognized after a reboot. So I thought I might just be missing some USB "wake-up" config on OS level or something.

For anyone having a similar problem: I fixed it by replacing the ICY BOX IB-DK4050-CPD by a rather recent Anker 575 USB-C Hub 12-in-1. Even though they use the same Ethernet chipset and driver, I suspect the newer firmware solved the issue:
