@dafta wow, your approach works, all i need its dhcp server in steamdeck, thank you!
Does the DHCP server not work for you? It should be included in systemd-networkd, and the configuration that's included in this script is supposed to enable the DHCP server on that network, lines 60 and 76.

I have no idea what happens with him, so I just use static address, also I executed this in terminal on steamdeck sudo ip addr add 192.168.100.2/24 dev usb0
for static ip
sudo ip link set usb0 up
Okay, that's interesting. I'll try and see if it works for me.
