So I've always built my own Arduinos, but for this new project I decided to buy a Gravitech Arduino Nano 3.0. I also bought an official UNO R3 just to have. I am having problems uploading sketches via USB. I get the following error on both the nano and the uno.
Arduino: 1.6.5 (Windows 7), Board: "Arduino Nano, ATmega328"
Build options changed, rebuilding all
Sketch uses 6,664 bytes (21%) of program storage space. Maximum is 30,720 bytes.

avrdude done. Thank you.
I am able to upload to both boards via an ArduinoISP board. I can also open the serial monitor and see Serial.print output via the usb, just can't upload sketches.
I am using the latest Arduino IDE. I have the correct boards selected and the correct COM ports. Using a Windows 7 64bit machine, also tried a Windows 8.1 laptop.
Things I have tried:
• Updating and rolling back drivers, from the IDE folder, windows update, and FTDI site.
• Uninstalling and reinstalling everything multiple times, IDE and drivers
• Reloading bootloader via the IDE using my ArduinoISP
• Holding and releasing the reset button many different ways
• 1uF cap soldered across reset and ground(it's removed now)
• Many different USB cables and ports
I've spent most of the day searching every site/thread I could find on the subject and I'm at a loss. Any ideas on what to try would be greatly appreciated. I can load my sketches via the ArduinoISP programmer, but I would rather be able to do it via USB to quickly make changes and read serial output.
Thanks!
