I have some problems to connect nexus 5 with eclipse. I am using windows 8.1 and I have installed the nexus drivers from google_usb->http://developer.android.com/sdk/win-usb.html
I can see my device in ADB(using adb -devices) and in DDMS on eclipse, but I can't send apps to debbug it, just nexus doesn't appear in target in eclipse. In Device Manager my nexus appear like Android Composite ADB Device
I have the developer options enabled and USB debugging too.

EDIT:
I only just tested with android studio and it works, but I don't understand why in eclipse doesn't work
