@Qu3Uk the message received in Windows, and the device manager that has an exclamation point next to the device.

Actually, I use the FTDI connector on my outdoor weather sensor to power it from the solar/Li-Ion charger board. Used angled headers to keep the height down. I'll try to post a picture asap.

@tbowmo more out of curiosity, and from someone that just got started on electronics, so please sorry if this sounds like very noob, but, would it not be safer to plug the V_TARGET LED to the +3.3v pin? How do you ensure that the resistor on the V_TARGET will have constant voltage and that will not blow from over voltage if the VCCio pin is depended on the the Motherboard power? Thank You and nice work

@hek said: If you have an Uno around your can use that for programming the ProMini. http://www.instructables.com/id/Arduino-Pro-Mini-Stand-Make-It-Reusable/ http://www.instructables.com/id/Uploading-sketch-to-Arduino-Pro-Mini-using-Arduino/ It's weekend and I finally have the time to give this another chance and guess what? It works! I manage to upload the sketch to my Pro Mini and successfully created my first ever MySensors sensor! Thank you so much for that!
