What's the chip just to the right of the USB connector?
You need to have the correct drivers for it.
My guess would be FT232RL.

which driver should i download VCP or D2XX driver?

Ok, I know that Arduino has a FTDI chip. See Where does OSEPP come from? - Bar Sport - Arduino Forum I do not know which driver to download. You might want to install both and see what happens.

VCP: Virtual COM Port

Also, OSEPP does not support the Arduino project. They have their own forum, so you are probably best off to ask them to help. Since your money went to them anyway.
