I am new to arduino. My first attempt to write a sketch to my Arduino Nano ver3.0. I would get the avrdude: stk500_getsync(): not in sync: resp=0x00 error message. I went through checking com port settings ect.
Here is what I discovered.
Here is what I did with the arduino connected.
I opened Windows Device Manager.
Then went down to Universal Serial Bus Controller
Next I opened Universal Serial Controller.
I update the driver to the ftdiBus found in the arduino driver folder
then I went up to Ports and opened the com port connected to the arduino.

I update the driver to the ftdiPort found in the arduino driver folder
Now Arduino IDE can see and write to my arduino.
I hope that this helps some one else that may be struggling with this same problem.
