Hmm, also eine andere Maus hat nichts gebracht. Beim zweiten Mal der gleiche Hänger, den ich nur mit Alt-F1/Alt-F7 wieder weggebracht habe. Allerdings steht davon dann nichts in der dmesg, die ich diesmal vom Erkennen der Maus bis zum Schluss anhänge:

Von dem Hänger dazwischen keine Spur. Welche Log-Dateien könnten noch Aufschluss geben? Vielleicht ist die Maus gar nicht die Ursache, sondern lediglich ein Indiz? Geben die letzten Zeilen der /var/log/boot.log einen Hinweis:

Allerdings sieht ziemlich jeder Bootvorgang genau gleich aus, auch der vorhergehende, der gut gelaufen ist.
Trotzdem gehe ich jetzt mal auf einen anderen USB Port.
