Hello, We know that dwc2 is the USB2.0 driver for DesignWare IP. But it only has host’s code without device’s code. So I have two questions: 1. Will I develop or port the part of device’s code if I want to use dwc2 to support both host and device’s functions? 2. Another question, I know that many chip companies use dwc2. How do they solve the question above? If anyone has a similar experience or know well about this dwc2 driver, please reply me. Any help will be greatly appreciated.
