One thing worth mentioning is that to resume from the remote with newer kernels you need to enable wake up on the actual receiver device aswell as the usb port.

lsusb will list your attached usb devices:

Code:

$ lsusb
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 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
[b]Bus 004 Device 002: ID 1934:[u]5168[/u] Feature Integration Technology Inc. (Fintek) F71610A or F71612A Consumer Infrared Receiver/Transceiver[/b]
Bus 004 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 002 Device 006: ID 0b38:0010 Gear Head 107-Key Keyboard
Bus 002 Device 005: ID 046d:c049 Logitech, Inc. G5 Laser Mouse
Bus 002 Device 003: ID 0bda:0151 Realtek Semiconductor Corp. Mass Storage Device (Multicard Reader)
Bus 002 Device 002: ID 1a40:0101 TERMINUS TECHNOLOGY INC. USB-2.0 4-Port HUB
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The bold line of text is my usb mce ir receiver. Use the device id (5168 in my case) with the following command to find your device in /sys/bus/usb/devices

Code:

$ grep 5168 /sys/bus/usb/devices/*/idProduct
/sys/bus/usb/devices/4-2/idProduct:5168

Now use that location to check if wakeup from the device is enabled with:

Code:

$ cat /sys/bus/usb/devices/4-2/power/wakeup
disabled

The following command will change this setting to enabled:

Code:

$ sudo sh -c 'echo "enabled" > /sys/bus/usb/devices/4-2/power/wakeup'

This setting will be reset on boot so to enable it on every boot I added the following line to my /etc/rc.local file (the first line is to enable wake up on the usb port, as per this wiki article.)

Code:

echo USB1 > /proc/acpi/wakeup
echo enabled > /sys/bus/usb/devices/4-2/power/wakeup

Make sure /etc/rc.local is executable with the command

Code:

sudo chmod +x /etc/rc.local

This got wake from the remote working for me, and after some testing it seems to work more reliably than on lucid...

lsusb gave me:

lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 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:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 002: ID 15c2:0038 SoundGraph Inc. GD01 MX VFD Display/IR Receiver
Bus 006 Device 002: ID 20e8:5821
Bus 006 Device 003: ID 04b4:0060 Cypress Semiconductor Corp

then "grep 0038 /sys/bus/usb/devices/*/idProduct" gives me:

/sys/bus/usb/devices/3-2/idProduct:0038

So... cat /sys/bus/usb/devices/3-2/power/wakeup:
"cat: /sys/bus/usb/devices/3-2/power/wakeup: No such file or directory"

What the?! Not sure where to go from here. Any ideas?
