Not working anymore with driver 1.20.1 for 8157 Realtek Semiconductor Corp. USB 10/100/1G/2.5G/5G LAN lan adapter

[SeDi343]

I am unsure what to do since from my point of view it should work, but the interface is not shown in ifconfig.

lsusb shows the device:

It seems like it is working for my 1Gbit Realtek Chipset
Bus 002 Device 005: ID 0bda:8153 Realtek Semiconductor Corp. RTL8153 Gigabit Ethernet Adapter
since there i get an ethernet connection, but not for the 5Gbit Realtek Chipset
Bus 002 Device 003: ID 0bda:8157 Realtek Semiconductor Corp. USB 10/100/1G/2.5G/5G LAN

With the old driver that comes with kernel 6.8.0-62-generic i get the 5Gbit speed with wrong values printed in ethtool

It was working with r8152-2.19.2

Update: I made it work temporarily on my os by rmmoding it and insmoding it again.
