| |
| You will see a list of authorized resume devices
| |
| | |
| EG.

| === more information on devices ===
| |
| * You can get more information on wakeup devices by typing the following in a console
| |
| lspci
| |
| | |
| You will see a list of PCI devices. The first coloumn in lspci will match the Sysfs node coloumn in /proc/acpi/wakeup
| |
| | |
| EG.

| == Enabling wakeup status for devices ==
| |
| * enable wakeup devices to resume the computer by typing the following where **** is replaced with the corresponding device
| |
| echo **** > /proc/acpi/wakeup
| |
| | |
| EG.
| |
| root@XBMCLive:~# echo USB0 > /proc/acpi/wakeup
| |
| root@XBMCLive:~# echo USB2 > /proc/acpi/wakeup
| |
| | |
| | |
| | |
| == Verification of wakeup status ==
| |
| This section discusses verifying proper operation of the resume function
| |
| | |
| === Verifying enabled devices ===
| |
| * Type the following to verify proper wakeup device status
| |
| cat /proc/acpi/wakeup
| |
| EG.
| |
| root@XBMCLive:~# cat /proc/acpi/wakeup
| |
| Device S-state Status Sysfs node
| |
| HUB0 S5 disabled pci:0000:00:04.0
| |
| XVR0 S5 disabled pci:0000:00:09.0

| XVR1 S5 disabled pci:0000:00:0b.0
| |
| XVR2 S5 disabled pci:0000:00:0c.0
| |
| PS2M S4 disabled pnp:00:08
| |
| PS2K S4 disabled pnp:00:09
| |
| USB0 S3 enabled pci:0000:00:02.0
| |
| USB2 S3 enabled pci:0000:00:02.1
| |

| [[right | color = lightblue | PS2M = Mouse ]]
| |
| | PS3K = Keyboard
| |
| | USBX = USB where X = bus number
| |
| | USXX = USB where X = double digit bus numbers
| |
| }} | |
| | |
| You should now see that your devices are enabled. Test your resume function at this time and verify proper operation.
| |
| | |
| === Troubleshooting auto-resume ===
| |
| If an enabled device resumes the computer from standby at an undesired time, you may choose to disable it by using the following command where **** is the device you wish to disable
| |
| echo **** > /proc/acpi/wakeup
| |
| | |
| EG.
| |
| enabling USB2 as an enabled wakeup device causes the computer to resume immediately..
| |
| root@XBMCLive:~# echo USB2 > /proc/acpi/wakeup
| |
| | |
| == Committing to rc.local ==
| |
| | |
| * Edit /etc/rc.local and add the echo commands required to enable authorized devices
| |
| | |
| EG.
| |
| #!/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.
| |
| echo USB0>/proc/acpi/wakeup
| |
| echo "rc.local has completed sucessfully." > /tmp/resume.log
| |
| exit 0
| |
| | |
| | |
| Your Wake-On-Device setup is now complete.
