Arduino nano select port option is blurred | Driver issue I have just bought arduino nano board. when i connect the board via usb, system detects the new device but i am not able to select port in arduino ide for writing any code on board. I checked my device manager it says

The drivers for this device are not installed. (Code 28)
There are no compatible drivers for this device.

I have also updated my board and library list in arduino ide.
please help me out?
on my nano board CH340G USB&lt;-->uart chip was present, so i installed driver for that chip and everything works fine now. :P
