Network Manager does not start since kernel 5.4.0-56-generic with Fritz WLAN Stick AC 860 plugged in

[Felix Haller]

Fritz WLAN Stick AC 860 (should be 057C:8503, Ralink mt7662u ) was working well with 5.4.0-54-generic (5.4.0-55 was never installed) but since -56 the startup process ends with disabled network manager (gnome wifi selector tells that NM is not running).

While writing this report the fritz stick was not connected to the machine.

This seems to be fixed with 5.4.0-65-generic.
