I am running Windows 7 (64-bit) and running the 1.6.7 IDE. Looking under the Ports in my device manager I see the Arduino UNO R3 (COM5) listed. It has the yellow triangle indicating that it is not working properly. I right clicked on it, selected update driver, selected Browse My Computer and navigated to the drivers folder in the Arduino 1.6.7 software. I then clicked "Update" but it says it cannot find a driver for my hardware.
Under the IDE menu Tools>COM it only lists COM1. There is no COM5 listed. probably because the driver is not working.
Any suggestions on fixing this?
Thanks in advance.
