Hi Xiaofan, This is very very helpful. Finally I have found the LibUSB example for Renesas Rx62N. So now I don't mind using custom driver. I don't see any reason to stick with HID. One thing, I will need, is to include this drivers in my installation utility NSIS. Is there any help on this, anywhere?
You said, I need to use libusb0.sys or winusb.sys. I have already install libusb0.sys using inf-wizard.exe. Is there any advantage of using winusb.sys? Thank you very much. Now I understand the point.
