I upgraded mythbuntu 11.10 to mythbuntu 12.04. I had a working MCE usb remote suspend/wakeup thing going for me. After the upgrade wake on usb does not work. The light on the usb ir-receiver does not flash either when trying to wake up. The computer resumes well with the power button.

I have the following in my /etc/rc.local:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

sudo sh -c "echo USB0 > /proc/acpi/wakeup"
sudo sh -c "echo USB1 > /proc/acpi/wakeup"
sudo sh -c "echo USB2 > /proc/acpi/wakeup"
sudo sh -c "echo USB3 > /proc/acpi/wakeup"
sudo sh -c "echo enabled > /sys/bus/usb/devices/3-1/power/wakeup"

exit 0

I have a similar problem with identical hardware on an Ubuntu install. After the upgrade on that, wake on usb keyboard doesn't work.

What I don't get is why it worked before the upgrade? What has changed?

Got it to work.

I created a new rule:

sudo gedit /etc/udev/rules.d/90-mcewakeup.rules

Entered this in with the correct product and vendor id's (with the help of lsusb):

SUBSYSTEM=="usb", ATTRS{idVendor}=="0471", ATTRS{idProduct}=="0815" RUN+="/bin/sh -c 'echo enabled > /sys$env{DEVPATH}/../power/wakeup'"

Edited one line in my grub (added "usbcore.autosuspend=-1 acpi_enforce_resources=lax"):

sudo gedit /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1 acpi_enforce_resources=lax"

After which:

sudo update-grub

After a reboot tested it and it worked.
