Public bug reported:
After upgrading from kernel version 6.11.0-26-generic to
6.11.0-29-generic, plugging my Xiaomi Poco X3 phone (LineageOS 21 /
Android 14) to Ubuntu with USB tethering enabled doesn't show the
connection in NetworkManager, and the device appears as type wwan
(unmanaged by NetworkManager), and doesn't get an IPv4 address, so it
cannot be used as a wired network device.
System reboots:
reboot system boot 6.11.0-29-generi Fri Jul 11 09:04 - 18:03 (08:58)
reboot system boot 6.11.0-26-generi Mon Jul 7 08:06 - 02:02 (3+17:55)

Ubuntu version
No LSB modules are available.
Description: Ubuntu 24.04.2 LTS
Release: 24.04
A possible workaround is
$ sudo tee /etc/udev/rules.d/70-persistent-rndis.rules > /dev/null <<EOF
SUBSYSTEM=="net", ACTION=="add", ATTR{address}==<<WRITE YOUR PHONE'S MAC
ADDRESS HERE>>, NAME="usb-tether"
EOF
$ sudo tee /etc/systemd/network/99-usb.network > /dev/null <<EOF
[Match]
Name=usb-tether
[Network]
DHCP=yes
EOF
Then
$ sudo systemctl restart systemd-networkd
$ sudo networkctl reconfigure usb-tether
Then
$ journalctl -u systemd-networkd -n 50 | grep usb-tether
should show
usb-tether: DHCPv4 client started
and the network be available (although still not visible in
NetworkManager).
