just bought 2 Arduino Nano clones.
They are using CH340G to communicate over usb.
Issue is that one device is showing up in Device manager (win7 x64) as com port 26 with CH340G driver and all works fine.
Other one is showing as Unknown device.
Is it possible that some firmware on the Atmega itself is missing or device is not working at the hardware level?
Does CH340G needs some form of firmware inside ATMEGA328 to work properly?
Just tested programming of not working one with USBAsp from ArduinoIDE and it works without any problems, so it seems that maybe usb chip is faulty :?
