Dies geschah bereits im Release Candidate 4.8 und ich dachte, es würde behoben werden, wenn der Kernel stabil wäre, aber ich habe das Problem immer noch. Der Kernel scheint meinen USB-Controller zufällig zurückzusetzen oder etwas in dieser Art zu tun. Im Grunde hören alle meine USB-Geräte zufällig auf zu funktionieren und ich muss einen Neustart des Systems erzwingen, damit sie wieder funktionieren, nur damit sie etwa 5 Minuten lang funktionieren, bevor es wieder passiert. Ich bin auf 4.7.6 zurückgegangen, damit ich mein System verwenden kann, aber 4.8 scheint einfach nicht mit USB funktionieren zu wollen. Das habe ich im Syslog gefunden und ich denke, es ist ein Protokoll des Problems.
