I am able to reproduce this on-demand on a fully-patched Ubuntu 20.04.
Same enclosure - Razer CoreX Chroma. Both the built-in Asix
AX88179-based gigE adapter and my Realtek RTL8153-based USB-to-ethernet
adapter exhibit this same problem when connected through the CoreX's USB
hub.
The same Realtek adapter plugged straight into my laptop has no problems
after extended use. Likewise, other high-traffic USB devices (and PCIe)
work fine through this enclosure. It is strictly an issue with USB-to-
GigE from what I've seen. This appears to be the USB controller in
question-

I'm not a kernel dev so I wouldn't know where to start in tracking this
down, but I can repro on-demand and am happy to provide whatever other
data is needed to someone who wants to get to the bottom of this.
Thanks
