I have problem with the random MAC address of rndis_host.
Therefore I have no chance to keep permanent settings on NetworkManager
(like DNS).
Every time I plug my phone to my computer, it get new MAC address, which
is wrong.
It would be nice, if in case of missing fixed MAC, rndis_host module
would generate MAC using on base of device serial, idProduct, idVendor.
In such a case MAC address would be always same for particular device.
That is possible only if the product has a serial. Otherwise it would
clash horribly if you use multiple devices of the same type. Does your
device have a serial?

Yes, it have. Please see attached output of
