Same problem with a desktop computer : after suspend, the computer wakes up
immediately (this seems related to kernel version : see my post above)
None of the solutions above disabling usb worked.
The only solution that worked for me is the one given by *M* in
http://ubuntuforums.org/showthread.php?t=1969615 : create a script in
/etc/pm/sleep.d containing :
#!/bin/bash
# Disables echi / ohci / uhci ports on suspend and reenables them on resume.
# Place this script in /etc/pm/sleep.d
function unbind_usb {
for driver in ehci ohci uhci; do
cd "/sys/bus/pci/drivers/${driver}_hcd";
ids=$(ls | grep :);
echo $ids > /tmp/DISABLED_$driver;
for id in $ids; do
echo "Unbinding $id";
echo -n "$id" > unbind;
disabled="$disabled $id";
done;
done;
}
function bind_usb {
for driver in ehci ohci uhci; do
cd "/sys/bus/pci/drivers/${driver}_hcd";
for id in $(cat /tmp/DISABLED_$driver); do
echo "Binding $id";
echo -n "$id" > bind;
done;
rm /tmp/DISABLED_$driver;
done;
}
case "$1" in
hibernate|suspend)
unbind_usb;
;;
thaw|resume)
bind_usb;
# Uncomment the following two lines if USB devices stutter after resume
# unbind_usb;
# bind_usb;
;;
*)
exit 1;
;;
esac;
exit 0;
And it workd perfectly in my case.
