I have read a stack of posts about similar problems, but I have not found a specific solution to my problem:
I’m evaluating openSUSE 13.2RC1 on a Lenovo Thinkcentre m93p. I am using a Logitech keyboard and mouse connected via a Unifying Receiver. I have created the following rule in /etc/udev/rules.d:
SUBSYSTEM==“usb”, ATTRS{idVendor}==“046d”, ATTRS{idProduct}==“c52b” RUN+="/bin/sh -c ‘echo enabled > /sys$env{DEVPATH}/…/power/wakeup’"
This should enable the receiver to wake the machine. However, when I suspend the machine, it will wake up after a couple of seconds. It must the the udev rule causing the problem, because the machine wakes up regardless of whether the receiver is plugged in or not. If I leave out the udev rule, nothing happens and I am unable to wake the machine from sleep.
My USB configuration looks like this:

I have tried different usb ports, but it doesn’t seem to make a difference.
My kernel is:

Any ideas would be welcome
