I have always had problems with wakeup of my media PC’s after a suspend or hibernation using my MCE (Microsoft media center) remote.
The problem was solved by enabling wakeup on the USB bus device. On some of my devices I also had to enable port on the ACPI (Advanced Configuration and Power Interface). The grub bootloader parameters might also need some changes.
The first thing to do is finding out which usb port Infrared reciever is connected.
lsusb will list your attached usb devices:
$ lsusb
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 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 003 Device 004: ID 046d:c71e Logitech, Inc.
Bus 003 Device 003: ID 046d:0b07 Logitech, Inc.
Bus 003 Device 002: ID 1784:0008 TopSeed Technology Corp. eHome Infrared Transceiver
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 009 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 010 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
The bold line of text is my usb ir receiver. Use the device id (0008 in my case) with the following command to find your device in /sys/bus/usb/devices
$ grep 0008 /sys/bus/usb/devices/*/idProduct
/sys/bus/usb/devices/3-1/idProduct:0008
Now use that location to check if wakeup from the device is enabled with:
$ cat /sys/bus/usb/devices/3-1/power/wakeup
disabled
The following command will change this setting to enabled:
$ sudo sh -c 'echo "enabled" > /sys/bus/usb/devices/3-1/power/wakeup'
This setting will be reset on boot so to enable it on every boot you have to add the line to your /etc/rc.local file. You must be root to update the rc.local file.
$ sudo nano /etc/rc.local
and add the below below line before exit(0):
echo enabled > /sys/bus/usb/devices/3-1/power/wakeup
Save with <Ctrl>o and exit with <Ctrl x>.
Make sure /etc/rc.local is executable with the command
$ sudo chmod +x /etc/rc.local
The next is the ACPI needs to up updated as well. First inspect the ACPI wakeup configuration:
$ cat /proc/acpi/wakeup
Device S-state Status Sysfs node
PCI0 S5 *disabled no-bus:pci0000:00
PEX0 S5 *disabled pci:0000:00:1c.0
PEX1 S5 *disabled
PEX2 S5 *disabled
PEX3 S5 *disabled pci:0000:00:1c.3
PEX4 S5 *disabled pci:0000:00:1c.4
PEX5 S5 *disabled
HUB0 S5 *disabled pci:0000:00:1e.0
USB0 S3 *disabled pci:0000:00:1d.0
USB1 S3 *enabled pci:0000:00:1d.1
USB2 S3 *disabled pci:0000:00:1d.2
USB3 S3 *enabled pci:0000:00:1a.0
USB4 S3 *enabled pci:0000:00:1a.1
USB5 S3 *enabled pci:0000:00:1a.2
USBE S3 *enabled pci:0000:00:1d.7
USE2 S3 *disabled pci:0000:00:1a.7
AZAL S5 *disabled
As you can see is USB0,USB2 and USE3 not enabled. For you is might be different.
I added the below lines as root to rc.local before exit(0):
$ sudo nano /etc/rc.local
The lines add is different to what others recommend. This is because you cat switch enable and disable by executing the echo “USB0” > /proc/acpi/wakeup twice.
status=`cat /proc/acpi/wakeup | grep "USB0" | awk {'print $3}'`
if [ "$status" = "disabled" -o "$status" = "*disabled" ]; then
echo "USB0" > /proc/acpi/wakeup
fi
status=`cat /proc/acpi/wakeup | grep "USB2" | awk {'print $3}'`
if [ "$status" = "disabled" -o "$status" = "*disabled" ]; then
echo "USB2" > /proc/acpi/wakeup
fi
status=`cat /proc/acpi/wakeup | grep "USE2" | awk {'print $3}'`
if [ "$status" = "disabled" -o "$status" = "*disabled" ]; then
echo "USE2" > /proc/acpi/wakeup
fi
The last thing was changing the grub startup paramerters.
$ cat /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
acpi_enforce_resources=lax"
GRUB_CMDLINE_LINUX=""
# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"
# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480
# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true
# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"
# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
You will have to change the GRUB_CMDLINE_LINUX_DEFAULT (marked bold).
$ sudo nano /etc/default/grub
and change
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1 acpi_enforce_resources=lax"
At last you will have to update grub:
$ sudo update-grub
Reboot and test.
Enjoy (some of) your suspend problems is over.
