/**
* @brief Enable USB for host/device connection
* @brief Enable the USB subsystem and associated hardware
*
* Function to enable USB for host/device connection.
* Upon success, the USB module is no longer clock gated in hardware,
* it is now capable of transmitting and receiving on the USB bus and
* of generating interrupts.
* This function initializes the USB core subsystem and enables the
* corresponding hardware so that it can begin transmitting and receiving
* on the USB bus, as well as generating interrupts.
*
* Class-specific initialization and registration must be performed by the user
* before invoking this, so that any data or events on the bus are processed
* correctly by the associated class handling code.
*
* @return 0 on success, negative errno code on fail.
