* To use this driver, you must:
* - If you are using a device with crystal-less USB, set up the clock recovery system (CRS)
* - Remap pins to be D+/D- on devices that they are shared (for example: F042Fx)
* - This is different to the normal "alternate function" GPIO interface, needs to go through SYSCFG->CFGRx register
* - Enable USB clock; Perhaps use __HAL_RCC_USB_CLK_ENABLE();
* - (Optionally configure GPIO HAL to tell it the USB driver is using the USB pins)
* - call tusb_init();
