Hello LarsR.
Thanks for the reply.
I followed your instructions step by step. Even wait 2 minutes to connect the usb cable and wait 2 more minutes to see if the port was detected. But still does not detect the port. Not have any SD memory connected. Get a USB-serial cable, where do I connect it?.
I ask for an apology because I do not speak English, but I still my best to write in English.
