problems with connecting phone or tablet to ADT

First things first, I'm new to this. I did peek a little on android development halv a year ago, and then I could connect my phone to test the apps.
Now I can't seem to do it anymore, however, I can on my macbook pro.



I tried updating these as well, but it says there are no updates available.


Anyone know what I can do? Should I just try reinstall everything? (ADT, eclipse)

Found the solution! All I had to do was download "samsung Kies" and now it works.
May the Android Dev journey begin!
