There may be some voltage tolerance issues with your PCs USB ports.  You may want try it with a USB hub and see if that helps any.

I tried it using an external power supply, I assume it would be the same as a usb hub? It was a converted PC power supply, so it should be pretty clean power.

No, not exactly.  With a USB hub the data lines are also regenerated.

Hello everyone, I realize this is an old post but I'd like to share my experience on this issue and its resolution.

So obviously I have the same problem. I purchased an Arduino Nano ATMega328 V3 from this seller on ebay.

Here is my setup:


Using Arduino IDE V.1.6.5, it didn't work. I plugged in the Nano, it found itself a driver, opened the IDE, set Tools > Board to "Arduino Nano" > Set Tools > Processor to "ATMega328" > Set Port of course. Didn't work.

So I tried it on another computer, Windows 7 with Arduino IDE V.1.6.5 as well and it worked. The only thing I can think of is that I have heavily modified my Arduino libraries with all kinds of updates. Perhaps that had something to do wth it.

So I uninstalled Arduin IDE from my original computer, the one that didn't work. Installed https://www.arduino.cc/en/Main/Donate and it worked. Out of pure curiosity, I also installed the original IDE V.1.6.5 and it also worked.

My conclusion is that one of the libraries I replaced was causing this problem.

I should also mention that the seller states that the CH340G model on this Nano replaces the FT232RL - not 100% sure what that means. I believe those parts are the modules that interface the board with the computer via USB. The ebay seller links this shady Russian site to install a driver. I didn't install the driver and still managed to get it working.
