Hi hudyj. I used the port closest to the TFCARD. It is the only one that triggers something in my Windows (new device attached sound).
Regarding the cable, I used one cable from a cooling pad for laptops (no branded).
I would really suggest you to try to use a UART cable, to check exactly what is happening with your device.
Which version of usb burning tool are you using?
I connect the 12V plug. This time I used factory USB A-A cable.
