ADB doesn't recognize my Galaxy Nexus - Win7

Question

I just bought a Galaxy Nexus, now I got a problem, my ADB doesn't recognize it. The Point is when I connect it, it shows it as Storage-Device on my Computer but it isn't listed as an ADB Device.

When I connect my other Phone (HTC Desire HD) it recognize it without any problems.

Some information about the System and Config:

1. I'm on Win7 Service Pack 1 64bit
2. Galaxy Nexus is in debugging mode
3. The Device isn't shown in ADB but Windows recognize it as Massstoragedevice
4. Eclipse and Googlepack is updated to the newest Version

Answer 1

Check if you have installed this package in your ADB "Google USB Driver package, revision 4"; if not do it.

Another possible solution could be downloading the drivers from here: http://www.samsung.com/us/support/owners/product/SCH-I515MSAVZW

This appears to work for the Samsung GT-i9250 version too.
