I have an RT-AX88U on 3004.388.8_4. I recently set up a USB adapter with a RTL8152B chip as the WAN interface. I got it to connect with some nvram tweaking (also renamed the interface from eth8 to usb0). Everything works except:
1) The web interface thinks the cable is disconnected.
2) The iptables nat table is empty and port forwarding rules aren't applied. This only affects IPv4. IPv6 seems to be working correctly without any intervention, including the IPv6 firewall rules in ip6tables. I can manually add a -j MASQUERADE target to the POSTROUTING chain and the various NAT rules to get things working again.
Not sure if I missed some configuration in nvram to change the WAN interface or there are some hardcoded things.
The logs look normal to me (aside from the missing VUPNP chain which I assume is caused by the same issue):
