Topic: USB serial Port not found (Read 4359 times) previous topic - next topic

About an hour I was able to upload onto my arduino Uno but now the USB serial Port won't come up for me to be able to select it and I can't upload anything.

I'm using a Mac, an Arduino Uno.  I've tried some of the suggestions that I found on the web but nothing seems to make a difference.

Help would be greatly appreciated :)

If you have the Serial Monitor ON (Displayed), close it, then disconnet the UNO from USB, reconnect the UNO and check if COM port is now available.

Your driver probably isn't installed properly. This is how I solved the problem.

Go to your Control panel > hardware and sounds > device manager > Ports

- then you should see "Unknown device". Double click on it
- Click on the "Driver" tab
- Click on "update Driver"
- Click on "Browse my computer for driver software"
- click "browse" and select the "drivers" subfolder in your Arduino folder.
- Click "next" and hopefully, your computer will install the driver for you successfully
Goodluck  :)

Do you have 1.0.3 or the beta arduino IDE?

Okay but they are on a Mac, so none of this applies.

When switching to the Duemilanove, did you remember to change the board type in the IDE?
