UE306 not functional under Debian (kernel 5.18) on Asus N550JV laptop

In /var/log/messages I see:

 

usbcore: registered new interface driver ax88179_178a

 

But the interface (eth0 or eth1) will not come up - "no such device".

 

Supposedly this adapter works out of the box with linux, but I don't find that to be the case. Anything I could try?

  @nbi1 Here's the complete dmesg output. This driver appears to be buggy. As this is for kernel 5.18 I have to assume it's the most current.

As we can see it blows up immediately upon registering. FYI, I blacklisted the r8169 driver which handles the native Realtek ethernet port. That shouldn't be necessary, but just to be safe I removed that driver from the picture - that made no difference.

  @nbi1 Having researched this further it turns out this is an old problem dating all the way back to 2014. For this problem to have festered for 8 years while tp-link markets these adapters as linux compatible is fraudulent as it clearly fails the use cases for many users. Mine is going back for a refund. tp-link will not bamboozle me again.
