* device mode, interrupts must be enabled within 500ms of this function being called to ensure
* that the host does not time out whilst enumerating the device. In host mode, interrupts may be
* enabled at the application's leisure however enumeration will not begin of an attached device
* until after this has occurred.

* Calling this function when the USB interface is already initialized will cause a complete USB
* interface reset and re-enumeration.
*
* \param[in] Mode Mask indicating what mode the USB interface is to be initialized to, a value
* from the \ref USB_Modes_t enum.
* \note This parameter does not exist on devices with only one supported USB
* mode (device or host).
*
* \param[in] Options Mask indicating the options which should be used when initializing the USB
* interface to control the USB interface's behavior. This should be comprised of
* a \c USB_OPT_REG_* mask to control the regulator, a \c USB_OPT_*_PLL mask to control the
* PLL, and a \c USB_DEVICE_OPT_* mask (when the device mode is enabled) to set the device
* mode speed.
*
* \note To reduce the FLASH requirements of the library if only device or host mode is required,
* the mode can be statically set in the project makefile by defining the token \c USB_DEVICE_ONLY
* (for device mode) or \c USB_HOST_ONLY (for host mode), passing the token to the compiler
* via the -D switch. If the mode is statically set, this parameter does not exist in the
* function prototype.
* \n\n
*
* \note To reduce the FLASH requirements of the library if only fixed settings are required,
* the options may be set statically in the same manner as the mode (see the Mode parameter of
* this function). To statically set the USB options, pass in the \c USE_STATIC_OPTIONS token,
* defined to the appropriate options masks. When the options are statically set, this
* parameter does not exist in the function prototype.
* \n\n
*
* \note The mode parameter does not exist on devices where only one mode is possible, such as USB
* AVR models which only implement the USB device mode in hardware.

* device mode, interrupts must be enabled within 500ms of this function being called to ensure
* that the host does not time out whilst enumerating the device. In host mode, interrupts may be
* enabled at the application's leisure however enumeration will not begin of an attached device
* until after this has occurred.

* Calling this function when the USB interface is already initialized will cause a complete USB

* \param[in] Mode Mask indicating what mode the USB interface is to be initialized to, a value
* from the \ref USB_Modes_t enum.
* \note This parameter does not exist on devices with only one supported USB
* mode (device or host).
*
* \param[in] Options Mask indicating the options which should be used when initializing the USB
* interface to control the USB interface's behavior. This should be comprised of
* a \c USB_OPT_REG_* mask to control the regulator, a \c USB_OPT_*_PLL mask to control the
* PLL, and a \c USB_DEVICE_OPT_* mask (when the device mode is enabled) to set the device
* mode speed.
*
* \note To reduce the FLASH requirements of the library if only device or host mode is required,
* the mode can be statically set in the project makefile by defining the token \c USB_DEVICE_ONLY
* (for device mode) or \c USB_HOST_ONLY (for host mode), passing the token to the compiler
* via the -D switch. If the mode is statically set, this parameter does not exist in the
* function prototype.
* \n\n
*
* \note To reduce the FLASH requirements of the library if only fixed settings are required,
* the options may be set statically in the same manner as the mode (see the Mode parameter of
* this function). To statically set the USB options, pass in the \c USE_STATIC_OPTIONS token,
* defined to the appropriate options masks. When the options are statically set, this
* parameter does not exist in the function prototype.

* device mode, interrupts must be enabled within 500ms of this function being called to ensure
* that the host does not time out whilst enumerating the device. In host mode, interrupts may be
* enabled at the application's leisure however enumeration will not begin of an attached device
* until after this has occurred.

* Calling this function when the USB interface is already initialized will cause a complete USB
* interface reset and re-enumeration.
*
* \param[in] Mode Mask indicating what mode the USB interface is to be initialized to, a value
* from the \ref USB_Modes_t enum.
* \note This parameter does not exist on devices with only one supported USB
* mode (device or host).
*
* \param[in] Options Mask indicating the options which should be used when initializing the USB
* interface to control the USB interface's behavior. This should be comprised of
* a \c USB_OPT_REG_* mask to control the regulator, a \c USB_OPT_*_PLL mask to control the
* PLL, and a \c USB_DEVICE_OPT_* mask (when the device mode is enabled) to set the device
* mode speed.
*
* \note To reduce the FLASH requirements of the library if only device or host mode is required,
* the mode can be statically set in the project makefile by defining the token \c USB_DEVICE_ONLY
* (for device mode) or \c USB_HOST_ONLY (for host mode), passing the token to the compiler
* via the -D switch. If the mode is statically set, this parameter does not exist in the
* function prototype.
* \n\n
*
* \note To reduce the FLASH requirements of the library if only fixed settings are required,
* the options may be set statically in the same manner as the mode (see the Mode parameter of
* this function). To statically set the USB options, pass in the \c USE_STATIC_OPTIONS token,
* defined to the appropriate options masks. When the options are statically set, this
* parameter does not exist in the function prototype.
* \n\n
*
* \note The mode parameter does not exist on devices where only one mode is possible, such as USB
* AVR models which only implement the USB device mode in hardware.
