suspend works, resume on usb does not

[ederopaa]

I upgraded two almost identical systems:
ubuntu 11.10 -> ubuntu 12.04
mythbuntu 11.10 -> mythbuntu 12.04

On both I had suspend/wake on usb working in 11.10. The prior on wireless mouse/keyboard and the latter on a usb ir/mce remote.

Now after the upgrade wake on usb does not work. I have to wake things up with the power button. The light on my ir receiver does not flash either.

The original settings in the /etc/rc.local have not changed:

#!/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

Any ideas how to get things working?

You are not alone.
I don't really understand the wakeup systems (12.04 or prior) but was using a similar script that checks the USB device for my keyboard and enables it if it was disabled. initially this script looked like it was failing to update /proc/acpi/wakeup but when I poked a little more I also noted that most of the devices in /proc/acpi/wakeup were now enabled by default instead of disabled. so I wonder if there is now setting(s) elsewhere that prevent wakeup from working.

I'll poke back here in the next couple days when I have more time to invest.

just glanced through your info again... I noted that you are updating a wakeup in path /sys/bus/usb/devices/*/power/wakeup
mine is "disabled" ATM
I will play with that when I get a chance ... thanks

Hey pammo, I have understood that you are supposed to enable the wakeup...but who knows. Let's hope there is a easy and fast solution to this.

Got it to work by Googeling and error.

On my Ubuntu and Wireless keyboard/mouse setup:

Created a new rule:

$ sudo gedit /etc/udev/rules.d/90-keyboardwakeup.rules

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

SUBSYSTEM=="usb", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c52e" RUN+="/bin/sh -c 'echo enabled > /sys$env{DEVPATH}/../power/wakeup'"

After a reboot it worked.

On my Mythbuntu and MCE remote setup:

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"

Then:

sudo update-grub

Then after a reboot tested it and it worked.

I don't know why the MCE needed the grub line?

Just upgraded from 11.10 to 12.04 in-line.

Contents of the /etc/rc.local are the same as before the upgrade:

echo US15 > /proc/acpi/wakeup
echo enabled > /sys/bus/usb/devices/4-3/power/wakeup

But unable to wake from USB.

Checking the 2 files I am editing, the /sys/usb/...../wakeup contents is "enabled".
The /proc/acpi/wakeup contents for US15 is "*disabled"

I can manually run the other to enable it, prefixing with a "sudo sh -c...." to the command.

I edited the contents to the following, but no further progress:

sudo sh -c "echo US15 > /proc/acpi/wakeup"
sudo sh -c 'echo "US15" > /proc/acpi/wakeup'

Can anyone suggest alterations that might be needed? Or how to trap further errors that are happening?

I thought that /etc/rc.local would be being executed as root on startup, so I should not need to elevate with the "sudo" call.

I know this file is being executed, as I commented out the 2nd line, and on reboot, the /sys/usb/..../wakeup file shows as "disabled"


Many thanks

jingo_man,

From your /etc/rc.local try to comment out the first line:

#echo US15 > /proc/acpi/wakeup
echo enabled > /sys/bus/usb/devices/4-3/power/wakeup

Then check you devices vendor and product id's with

$lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 007 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 046d:09a5 Logitech, Inc. Quickcam 3000 For Business
Bus 003 Device 002: ID 046d:c52e Logitech, Inc.

and create a new rule with

$ sudo gedit /etc/udev/rules.d/90-keyboardwakeup.rules

to insert them in the file. In my case 046d and c52e:

SUBSYSTEM=="usb", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c52e" RUN+="/bin/sh -c 'echo enabled > /sys$env{DEVPATH}/../power/wakeup'"

reboot and try it.

@ederopaa

thanks, that worked like a charm, when i plugged in the values for my MCE receiver device.

have they deprecated the older method? why the change to this style?

[SAM0]

cheers, great post.

[fatski]

CHeers for this solution man.

I wonder why they made it so much harder.

Be nice if this was configurable through power settings to be honest, it's got to be a good thing to have for a lot of people with HTPC's or wireless keyboards / mice.
