How do I configure Wake-On-USB properly on a 10.04 or 10.10 Ubuntu (2.6.36 and higher if needed)? (Wake-on-USB is when the computer is asleep and for example a USB Keyboard event wakes up the machine!) The notebook is an Acer Aspire Timeline X 1830T. I don't know in which way the Linux Kernel supports the controllers.

There are different ways to approach this, for example /proc/acpi/wakeup... or UDEV... or something with HAL?

/proc/acpi/wakeup shows every device in S4, but I need S3.

• S4, which is Suspend-To-Disk afaik... doesn't seem to work either if I echo USB1 into the wakeup table. It just sets an S4 flag.
• can I get the USB ports in S3?

I want to make the machine wakeup from Suspend-To-Ram (S3, ACPI standard) in case a key on my external keyboard is pressed. It only wakes up if a key on the internal Laptop keyboard is pressed... from Suspend To Ram. It seems if I plug in a USB mouse, that the USB port isn't even powered. I have no BIOS option to change this.

Further specific information regarding the device:

If this doesn't work I have to properly explain why :( - but I think it is very hard to research this kernel internal. Any hints for good information here? I hope it's possible... I'm just looking for any solution.

edit: this, waking up on USB, works on Windows!

Thanks a lot, Marius
