I'm using Ubuntu 12.04.3 LTS and I can't wake up my desktop PC from suspend with a USB device (e.g USB mouse). The entire process of suspending/resume works perfectly but the only way to resume it's by pressing the PWR Button. Here are some logs that I hope could help someone troubleshooting my issue: http://paste.ubuntu.com/6468990/. I tried to follow this guide to enable wake up from USB devices but with no luck: http://bernaerts.dyndns.org/linux/74-ubuntu/220-ubuntu-resume-usb-hid. Any suggestions are appreciated, thanks.
I finally managed to solve this issue by upgrading to the kernel v3.12.0. Now the whole process of suspend/resume, including wake up with my USB mouse works!
