I am trying to have the duovero wakeup on usb activity, but nothing except uart/serial activity seems to wake the device. I have tried the following:

 

root@duovero:~$  cat /proc/cmdline

console=ttyO2,115200n8 vram=16M root=/dev/mmcblk0p2 rw usbcore.autosuspend=-1 rootfstype=ext3 rootwait

root@duovero:~$  cat /sys/bus/usb/devices/*/power/autosuspend_delay_ms

-1000

-1000

-1000

-1000

root@duovero:~$  echo enabled | tee /sys/bus/usb/devices/*/power/wakeup

enabled

root@duovero:~$  cat /sys/bus/usb/devices/*/power/wakeup

enabled

enabled

enabled

enabled

root@duovero:~$  echo on | tee /sys/bus/usb/devices/*/power/control

on

root@duovero:~$  cat /sys/bus/usb/devices/*/power/control

on

on

on

on

root@duovero:~$  echo 1 | tee /sys/kernel/debug/pm_debug/enable_off_mode

1

root@duovero:~$  cat /sys/kernel/debug/pm_debug/enable_off_mode

1

 

Now when I put the system into suspend mode only pressing a key in the serial port window gets it out. Is there something else that needs to be done?
