[Pkg-utopia-maintainers] Bug#1104879: network-manager: USB tethering not working

[xft233]

Package: network-manager
Version: 1.52.0-6
Severity: normal

Dear Maintainer,

   * What led up to the situation?
   I connected my Android phone to the system via USB and enabled USB tethering.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   After enabling USB tethering, the expected interface (e.g., `wwx*`) did not show up in 'nmcli device status', and NetworkManager did not automatically manage it.
   I had to manually run `ip link set <interface> up and then `dhclient <interface> to get connectivity.

   * What was the outcome of this action?
   NetworkManager ignored the USB tethered interface.

   * What outcome did you expect instead?
   USB tethering  working.
