How do I detect if the USB cable is plugged in? and charging?

That is it!

I want to detect if the USB cable is plugged in and if it is charging the batteries.
Is there any way to acomplish this?

thanks!  :)

Well... may I have to look for some GPIO or something like that? How can I read a GPIO pin?

The gpio pins aren't hard to read, mapped to /sys/jz somewhere, someone in the inc channel will know off the top of their head.  Gpio documentation is on the dingoo-linux googlecode wiki, think I saw something about usb, though there's probably a better way of seeing, could just ping 10.1.0.1 or whatever the computers up is over the usb
