usb audio interface and autosuspend

Hi at all,

I recently put my usb audio interface back on the job and recognized, that I could no longer autosuspend it via sysfs (as descirbed here: https://wiki.archlinux.org/index.php/Po … tosuspend), since /sys/bus/usb/devices/DEVICE/power/control and autosuspend are not created.
It used to work on older kernels. I'm now using latest linux-lts (3.10.27-1-lts).

Is it possible to reenable this feature? I always found it quite handy, since the interface is usb powered and I mostly use it with my laptop.

lsusb:

Bus 006 Device 003: ID 0582:00e6 Roland Corp. EDIROL UA-25EX (Advanced mode)

Regards,
Marcus
