 In addition to core changes, library need to be ported to your platform. Don't worry, tinyusb stack has already done most of heavy-lifting. You only need to write a few APIs
 
-1. `TinyUSB_Port_InitDeviceController()` hardware specific (clock, phy) to enable usb hardware. This API is called as part of TinyUSB_Device_Init() invocation.
+1. `TinyUSB_Port_InitDevice()` hardware specific (clock, phy) to enable usb hardware then call tud_init(). This API is called as part of TinyUSB_Device_Init() invocation.
 2. `TinyUSB_Port_EnterDFU()` which is called when device need to enter DFU mode, usually by touch1200 feature
 3. `TinyUSB_Port_GetSerialNumber()` which is called to get unique MCU Serial ID to used as Serial string descriptor.
