Description Arvid Requate

2010-12-16 11:03:49 CET

univention-client-kernel-image-2.6.35.7-univention.thinclient.13   ist zur Zeit ohne das Modul 'usbcore' gebaut, das man z.B. für/sys/bus/usb/devices/usb1/power benötigt.

Comment 1 Arvid Requate

2010-12-16 11:51:08 CET

Die Aussage an Comment 0 stimmt nicht, usbcore ist fest eincompiliert.
Es fehlen folgende Optionen in der Kernel-Konfiguration, um USB-Devices suspenden zu können:

CONFIG_PM_RUNTIME=y
CONFIG_USB_SUSPEND=y

Comment 2 Arvid Requate

2010-12-22 16:34:48 CET

In univention-client-kernel-image-2.6.35.7-univention.thinclient.17 im Release-Scope ucs_2.4-0-opendvdi  sind die beide Optionen aktiviert.

Damit lässt sich Autosuspend von USB-Devices dann aktivieren:
for  f in /sys/bus/usb/devices/*-*/power/level; do echo auto > $f; done

Comment 3 Moritz Muehlenhoff

CONFIG_PM_RUNTIME und CONFIG_USB_SUSPEND sind im Ubuntu-Kernel (Basis von UCC 1.0) aktiviert.
