Nachdem ich den Kernel auf 4.12.5 upgedated habe startet brickd nicht mehr. Woran kann das liegen?

Ich habe libusb neu installiert.

Laut der Fehlermeldung fehlt das usbfs.

 

kannst du mal

dmesg | grep usbfs

ausführen?

 

Es sollte sowas wie

[    0.187862] usbcore: registered new interface driver usbfs

ausgegeben werden.
