Your approach doesn't sound right to me. I don't believe you can control
the PINs of the USB host interface directly. You need to configure the
host controller - OS is giving you interfaces and abstration for the
different device types. All you need to do is to implement the end
points as per spec in your hardware and write handler for your
hardware's USB ids.
