I am running Win (32bit) and find that it will not recognize my new Uno R3. After some research, I tried in on a different computer and was able to get it work and was able to program it. Switching back to my Win7 machine, It is not recognized. Checking device manager shows no unknown devices. Any ideas on beating my Win7 into submission?
Are the Arduino serial port drivers installed?
yes it is installed
USB2 or USB3 port; there seem to be issues when using an USB3 port.
Bad port on PC?
