How do I switch from Android AVD to real hardware on Mac Eclipse-SDK?

I am using Ecli开发者_StackOverflowpse on Mac with Android SDK. I have the emulator working with my code and today I borrowed an Android that I would like to test on.

I have run 'adb devices' from the command line, but I think the problem is more fundamental at the USB hardware detection level.

What tools do I use to troubleshoot this?

Enable USB debugging on your device.

1. On Android 3.2 or older, you can find the option under Settings > Applications > Development.

2. On Android 4.0 and newer, it's in Settings > Developer options.

3. As stated by Dan .. On Android 4.2 and newer, Developer options is hidden by default. To make it available, go to Settings > About phone and tap Build number seven times. Return to the previous screen to find Developer options and then enable USB Debugging
