[Regression] USB wakeup problem on Toshiba Portege R500

[Rafael J. Wysocki]

Hi Alan,

Unfortunately, the following commit:

commit 6fd9086a518d4f14213a32fe6c9ac17fabebbc1e
Author: Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>
Date:   Wed Dec 17 17:20:38 2008 -0500

    USB: automatically enable wakeup for PCI host controllers

    Signed-off-by: Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>
    Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxx>

causes a regression to appear on my Toshiba Portege R500.

The regression is that when suspended to RAM, the box wakes up immediately
unless 'disabled' is written into the /sys/devices/.../power/wakeup file of the
EHCI controller.  I know of at least 10 different boxes out there that are
going to have similar problems forcing their users to use manual workaround.

Also, it wakes up on a USB mouse activity, which I don't want it to do, so in
fact I have to write 'disabled' to the /sys/devices/.../power/wakeup files of
all USB controllers.

I'm not sure if the commit went into the right direction.

Thanks,
Rafael
