Liebe ExpertInnen,
auf meinem System (DELL Precision 5510) wächst die Logdatei uvcdynctrl-udev.log unkontrolliert, sobald ich meine Webcam an den USB-Port anstecke. Wenn ich die Datei lösche und die Kamera nicht am Port habe, wird sie nicht geschrieben. Schließe ich die Kamera an, füllt sich die Datei in Minutenschnelle Gigabyte-weise. Stecke ich die Kamera wieder ab, wird die Datei dennoch weitergeschrieben und wächst uferlos.

Im Netz gibt es dazu einige Themen: https://askubuntu.com/questions/177312/filesystem-filling-up-due-to-large-uvcydnctrl-udev-log-file, https://askubuntu.com/questions/766263/why-is-there-an-ever-growing-uvcydnctrl-udev-log-file-filling-up-my-harddisk und auch hier https://forum.ubuntuusers.de/topic/riesendatei-uvcdynctrl-udev-log-waechst-immer-/. Doch als Lösung werden leider nur das Löschen der Datei bzw. workarounds a la Cronjob-Löschungen benannt.
Was macht /lib/udev/uvcdynctrl? Brauche ich das, um meine Webcam (Sandberg 1080P HD) zu betreiben? Wie kann ich einen funktionierenden Treiber für die Kamera installieren?
Herzlichen Dank für jeden Tipp.
