usb0 unmanaged (g_ether)

[Ana Rodriguez Lopez <rodrilopez ana gmail com>]

Hi!

The usb0 connection is not working. The device is shown as unmanaged by
nmcli:

DEVICE    TYPE      STATE      CONNECTION
eth0      ethernet  connected  Ethernet  
usb0      ethernet  unmanaged  --        
sit0      iptunnel  unmanaged  --        
lo        loopback  unmanaged  -- 


The g_ether module is loaded. I set fixed MAC address with
`/etc/modprobe.d/g_ether.conf` and it seems to work:


using host ethernet address: 8E:8E:76:6C:34:0E
using self ethernet address: 8E:8E:76:28:44:AB
usb0: HOST MAC 8e:8e:76:6c:34:0e
usb0: MAC 8e:8e:76:28:44:ab
using random self ethernet address
using random host ethernet address
g_ether gadget: Ethernet Gadget, version: Memorial Day 2008
g_ether gadget: g_ether ready


The output of `lsmod` is:

In NetworkManager journalctl the only references are:

Any idea why the device is not managed by NM?


Thanks!
