Steve and Andrey:

It turns out that the proposed solution for your problem causes a
regression on other ASUS computers (see Bugzilla 43278).  Rafael's got a
proposal for a replacement.

Can you try out the patch attached to comment #61 of Bugzilla 42728?  It
may even allow USB wakeup to work for you (but I wouldn't count on it!).
Thanks.
I added the patch against 3.4 and my laptop still suspends.

And no, wakeup still doesn't work.

Tested-by: Steven Rostedt <rostedt@goodmis.org>
Thanks!

Unfortunately, I have no idea what to do to make wakeup work on the
affected machines.
Andrey, Stephen,

We still have problems with this patch in https://bugzilla.kernel.org/show_bug.cgi?id=43278
so some more testing will be necessary, I'm afraid.

I will send a series of ACPI and PCI patches I have collected so far,
that I'd like you to test on top of kernel 3.4.0 with commit
151b61284776 reverted.

Please let me know if suspend/wakeup work for you with these patches applied.

Thanks,
Rafael
