Looking at the code - well, AX88772B is not supported. You need AX88772A (or some other variant with PID 7720). You can still but such an USB-LAN adapter, but double check the description (I found some that were advertised as AX88772A , while in technical details they had AX88760). I have (~10 years) old Gembird NIC-U1, it is AX88772A based. Also look for "UGREEN USB 2.0 to 10/100Mbps Ethernet Network Adapter", one (local) seller put PCB photos showing AX88772A, I will order one to verify it.
