- * interface to control the USB interface's behaviour. This should be comprised of
- * a USB_OPT_REG_* mask to control the regulator, a USB_OPT_*_PLL mask to control the
- * PLL, and a 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 USB_DEVICE_ONLY
- * (for device mode) or 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.

- *
- * \note To reduce the FLASH requirements of the library if only fixed settings are 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 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.

- * \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.
