Eclipse won't recognize my android phone -> Can't debug

Question

All of a sudden Eclipse stopped recognizing my android device. So when I hit the Play-Button I get the following message:

No compatible targets were found. Do you wish to add a new Android Virtual Device?

Strangely on my device it says that USB-Debugging is connected, as soon as I plug it into my macbook.

What could be the problem here? Thanks!

PS: I'm using a Samsung Galaxy i5800 and a MacbookPro.

First of all you should check if your adb daemon is run (I assume you have android sdk installed). Please try taping this in terminal:

adb devices

And if there is nothing after List of devices attached try restarting server:

sudo adb kill-server
sudo adb devices

I recently discovered that I had switched a looking mini-usb power cable with a mini-usb data cable (the former was to recharge a bluetooth keyboard for a Nexus 7). Very, very frustrating, as the cables seem to be identical minus a data wire (as there doesn't seem to be a way to tell without switching cables (I.E., there's no indicator that yes, the phone is plugged in, but it isn't communicating (as opposed to being a driver problem))).

Im using a samsung galaxy s3. I had the same problem. found out that the reason it read the phone in the first place was cause i was teathering. So i selected teather and that solved it.
