问题
I can't seem to gain access to this function, it should allow me to set the usb mode on my device programatically (which is what I'm trying to do).
I can import the package where it is supposed to be, but it isn't available.
I know it exists as there are apps that use the function all over the place! its just my eclipse/ build environment can't find the damned thing.
