It seems that the library is not able to open a connection with my Arduino Nano ATmega328 (old bootloader) even if it is correctly identified. It is something related to the UART protocol, I suppose. The following is the avrdude output while uploading from Arduino IDE:

What I get is that it doesn't receive any data from the Arduino during the init phase. Can someone please help me understanding the problem or redirecting me to some documentations/specifications?

seems to be the bug with your hardware...

Actually, what is the VID:PID?

Found the issue, I'll have time on Sunday to fix it. Thanks for locating the bug!

I fixed this problem with below codes in 'UartWinCH34x.java'.

// USB_TYPE_VENDOR | USB_RECIP_DEVICE | USB_DIR_OUT

private static final byte REQTYPE_HOST_TO_INTERFACE = (byte) (UsbConstants.USB_TYPE_VENDOR | UsbConstants.USB_DIR_OUT);

// USB_TYPE_VENDOR | USB_RECIP_DEVICE | USB_DIR_IN

private static final byte REQTYPE_INTERFACE_TO_HOST = (byte) (UsbConstants.USB_TYPE_VENDOR | UsbConstants.USB_DIR_IN);
