Hi All,
We are using custom board with Gingerbread Android OS with kernel version 2.6.37. As part of our design, we are using SMSC LAN9512 for ethernet and more USB 2.0 PHY's.
Here everything is working good apart from it's high power consumption. If i enable auto suspend through command line by typing
echo "auto" > /sys/bus/usb/devices/1-1/power/control
echo "auto" > /sys/bus/usb/devices/1-1.1/power/control
echo "auto" > /sys/bus/usb/devices/1-1.3/power/control
it is going to low power mode and resuming on remote wakeup events properly.
Here 1-1(Main USB Hub), 1-1.1(Ethernet or LAN) and 1-1.3(Mouse).
But How can i enable auto suspend by default as part of driver loading without typing above commands manually through command line?
I put .supports_autosuspend = 1 in my usb hub driver
static struct usb_driver smsc9500_driver = {
.name = "smsc9500",
.id_table = products,
.probe = smscusbnet_probe,
.suspend = Smsc9500_suspend,
.resume = Smsc9500_resume,
.disconnect = smscusbnet_disconnect,
.reset_resume = Smsc9500SystemResume,
.supports_autosuspend = 1,
};
can anyone please help me?
Thanks,
Naresh
