Comment(by lindi):

 I am unable reproduce this bug. Here's what I did:

 1) boot andy-tracking b4136a36f31a65d0 with patch for #2240
 2) apm -s
 3) press power button to resume
 4) connected usb keyboard to phone
 5) ifconfig usb0 down
 6) echo host > `find /sys/devices -name usb_mode`
 7) echo 1 > `find /sys/devices -name hostmode`
 8) hit spacebar on keyboard

 and observed
