Hi Thomas,
As you said, there is an udev rule setting USB gadget devices as
unmanaged (85-nm-unmanaged.rules):
# USB gadget device. Unmanage by default, since whatever created it
# might want to set it up itself (e.g. activate an ipv4.method=shared
# connection).
ENV{DEVTYPE}=="gadget", ENV{NM_UNMANAGED}="1"
`$ nmcli device set usb0 managed yes` works, the device is then shown as
unavailable (connection-assumed):
DEVICE TYPE STATE CONNECTION
eth0 ethernet connected Ethernet
usb0 ethernet unavailable --
sit0 iptunnel unmanaged --
lo loopback unmanaged --

But I still cannot connect my profile UsbHost over usb0:
