[Rykel from Singapore <rykel98@xxxxxxxxx>]

I am running Ubuntu 10.10 with kernel 3.0.6 and found that none of my
USB and Bluetooth devices can wake up my system from Suspend. This is
annoying and I do not know how I can set the laptop to resume at the
press of a Bluetooth mouse button or USB keyboard key - much like it
does in Windows and more notably, Mac.

Title:
  Need /proc/acpi/wakeup tweaks to enable mousepad and USB to wake up
  from suspend

Status in “gnome-power-manager” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: acpi-support

  I have a HP Pavillion dv1240us.  I am running Ubuntu 7.04 (devel packages).  I find that if I suspend my laptop by selecting System --> Quit --> Suspend, events from the Synaptics mouse and from the USB ports fail to wake the system.  After tracking this down with the ACPI developers, I eventually determined that the necessary flags weren't set in /proc/acpi/wakeup.  I would very much like to see updates to the various Ubuntu versions that caused the needed flags to be enabled by default.
  I don't know if this bug should be assigned against acpi-support, powersaved, acpid or some other package.

  On my machine, I get:
  # cat /proc/acpi/wakeup
  Device Sleep state Status
  PCIB 5 disabled
   LAN 5 disabled
  PS2K 3 disabled
  PSM1 3 disabled
  USB0 3 disabled
  USB1 3 disabled
  USB2 3 disabled
  USB7 3 disabled

  If I run:
  # echo PSM1 > /proc/acpi/wakeup
  # echo USB0 > /proc/acpi/wakeup
  # echo USB1 > /proc/acpi/wakeup
  # echo USB2 > /proc/acpi/wakeup
  # echo USB7 > /proc/acpi/wakeup
  then, when I plug in a USB device, the system wakes up.
  This also causes my Synaptics mousepad to wake up the machine if I touch the mousepad or click one of the buttons.

  After running these commands, "cat /proc/acpi/wakeup" gives me:
  Device Sleep state Status
  PCIB 5 disabled
   LAN 5 disabled
  PS2K 3 enabled
  PSM1 3 enabled
  USB0 3 enabled
  USB1 3 enabled
  USB2 3 enabled
  USB7 3 enabled
