[Fei Luo (骆飞)]

if a USB keyboard/mouse/HID device is not plugged in, the
 XO will not go into suspend automatically too.

Comment(by greenfeld):

 This is by design; if a USB keyboard/mouse/HID device is plugged in, the
 XO will not go into suspend automatically.

 This is because going into suspend turns off USB power, making it
 impossible to wake up the XO via the USB device.

 If you really want to go into suspend while a USB keyboard and/or mouse is
 connected, remove the "hid" entry from /etc/powerd/flags/usb-inhibits.
