Installing a USB Driver

Development Tools IDE 1.x
1

Can someone help me connect my Arduino? Probably this is the most frequently asked question, but I cannot find a good answer.

Host system: Windows7 64-bit.
IDE: Arduino 1.6.6.
Arduino: UNO R3.

My first try at the Arduino. I've been using the MSP430 which is very easy to use, but the Arduino seems to require a bit more Windows knowledge.

So I'm running the IDE and it's telling me that it's using COM56. However, Windows says it's using COM59 recognized as "Arduino Uno". Ugh. >:(

I've tried rebooting, unplugging the Uno, start/restart, everything I can think of.

At a loss on how I tell them to talk to each other. Any hints?

thank you.

In Tools -> Ports, is COM59 available? If so, select it.

Also - it is not sufficient to state that you're using an Uno R3, as a large number of vendors selling Arduino clones refer to their boards as Uno R3's - when they use a different chip for USB<->serial, and hence require different drivers.

thank you. After I rebooted/powered-down/restarted a few times and waited 1/2 hour, it worked...
