Hi guys, I know I am replying to a year and half old post, but I ran in to a problem with my V6 and win10. The driver for the cp210x was set to use COM4 and the driver the CH340 also was set to take COM4. I had to go into device manager to find out why I could not upload to the bitx. It did work yesterday somehow. Moving the cp210x to a free com port fixed the problem. The CH340 driver for the nano works again with the arduino IDE.
