I have always had problems with wakeup of my media PC’s after a suspend or hibernation using my MCE (Microsoft media center) remote.<\/p>\n
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.<\/p>\n
The first thing to do is finding out which usb port Infrared reciever is connected.<\/p>\n
lsusb will list your attached usb devices:<\/p>\n

Use the device id (0008 in my case) with the following command to find your device in \/sys\/bus\/usb\/devices<\/p>\n
$ grep 0008 \/sys\/bus\/usb\/devices\/*\/idProduct\r\n \/sys\/bus\/usb\/devices\/3-1\/idProduct:0008<\/pre>\nNow use that location to check if wakeup from the device is enabled with:<\/p>\n
$ cat \/sys\/bus\/usb\/devices\/3-1\/power\/wakeup\r\n disabled<\/pre>\nThe following command will change this setting to enabled:<\/p>\n
$ sudo sh -c 'echo \"enabled\" > \/sys\/bus\/usb\/devices\/3-1\/power\/wakeup'<\/pre>\nThis 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.<\/p>\n
$ sudo nano \/etc\/rc.local<\/pre>\nand add the below below line before exit(0):<\/p>\n
echo enabled > \/sys\/bus\/usb\/devices\/3-1\/power\/wakeup<\/pre>\nSave with <Ctrl>o and exit with <Ctrl x>.<\/p>\n
Make sure \/etc\/rc.local is executable with the command<\/p>\n
$ sudo chmod +x \/etc\/rc.local<\/pre>\nThe next is the ACPI needs to up updated as well. First inspect the ACPI wakeup configuration:<\/p>\n

The lines add is different to what others recommend. This is because you cat switch enable and disable by executing the echo\u00a0 “USB0” >\u00a0\u00a0 \/proc\/acpi\/wakeup<\/strong> twice.<\/p>\n
