Make laptop to wake up by keyboard and mouse

The only way I can wake up my laptop (HP Elitebook 8460p) from suspend is by pressing the power button. Neither the built-in keyboard/mouse nor the external ones (connected via USB) wake the laptop up. Things I already tried: * Enabling the USB devices in /proc/acpi/wakeup. * Checking the bootlog to find out the /dev paths of the USB mouse/keyboard, then: udevadm info -a -p $(udevadm info -q path -n /dev/input/mouse2) I then checked for every device in the list using: cat /sys/devices/.../power/wakeup if it is possible to enable it, and if so, I do that. * I have enabled wake on USB in the BIOS. Here some outputs you might need: **$ uname -a** Linux oliarch 2.6.38-ARCH #1 SMP PREEMPT Tue May 10 08:05:04 CEST 2011 x86_64 Intel(R) Core(TM) i5-2540M CPU @ 2.60GHz GenuineIntel GNU/Linux **\# lsusb** Bus 001 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 002: ID 8087:0024 Intel Corp.
