Why do you want to skip the wakeup setting in that case?

Because that's what the 151b61284776 commit did.  Also, the quirk marks 
the controller as not wakeup-capable.

Still, it's worth testing.  Andrey and Steve, here's an updated patch 
which should leave wakeup enabled on your EHCI controllers.  If you 
don't have a USB keyboard handy for generating a wakeup signal, you 
can test the wakeup functionality by doing:

	echo enabled >/sys/bus/usb/devices/usb1/power/wakeup
	echo enabled >/sys/bus/usb/devices/usb2/power/wakeup

before suspending.  (In fact you need only one of those two lines, but
at the moment I forget which -- probably the usb2 one.)  Then while
the system is asleep, either plugging or unplugging a USB device
directly into the computer should cause it to wake up.

I applied the patch, it suspends and resumes fine, but still no wakeup.

I even plugged in a USB keyboard, suspended, and tried to wake it up
with that. That did not work. I even enabled what you stated above, with
no effect (with keyboard or usb storage).

This suggests that the original version of the patch is superior.  
There's not point in saying the controller is wakeup-capable and trying 
to enable wakeup if it's not going to work.
