add option for usb device wakeup settings

hello,

for years now it's always a hassle using suspend . resume only works with the power button, but not with usb keyboard or mouse.

you always need to tune power/wakeup settings via script foo like this to make it work:

   echo enabled >/sys/devices/pci0000:00/0000:00:1a.0/usb3/power/wakeup
   echo enabled >/sys/devices/pci0000:00/0000:00:1d.1/usb7/power/wakeup
   echo enabled >/sys/devices/pci0000:00/0000:00:1d.1/usb7/7-1/power/wakeup
   echo enabled >/sys/devices/pci0000:00/0000:00:1a.0/usb3/3-2/power/wakeup

there are tons of reports on the net and 100 variations, how people fix this.

there is also this long standing ticket in ubuntu: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/606756

could we please get some gui option to enable/disable wakeup for usb devices in xfce4-power-manager (and probably other power setting applets) ?

that would increase acceptance in using auto suspend and would safe a lot of wasted electrical power on this planet.

thank you
