Hello,
After many trys I still am not able to get wakeup from suspend to ram by usb mouse/keyboard to work. The only way I can wakeup my laptop is by pressing the power button...
I know that it is possible, since under ubuntu it used to work.
Here are the, in my opinion, relevant outputs:

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

disabledIf I enable this, the laptop always (even without any usb device plugged in) wakes up immediately after suspend!

enabledI tried all combinations of disabled/enabled of the devices and enabling everything in /proc/acpi/wakeup, but nothing works. The only sort of success is, as I mentioned above, enabling /sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/power/wakeup makes the laptop wakeup immediately (after 1 second or so) after suspend.
I am pretty sure it might be a kernel issue, since some people already experienced this problem as well and it was fixed with another kernel version (even though that was related to kernel 2.6.33 or so...)
When can one expect the 39 kernel to be stable? I don't really want to compile it myself, I think I am too unexperienced for that.
Best regards and thanks in advance,
Jan Oliver

The problem is gone after going to Kernel 39 in testing.
