@Digital Awakening, Jellybean is the name of the OS used by Nexus 7, Android 4.1.
@JimHawkins, Windows recognizes it fine and opens the external drive file navigator.
@leo877 and The Zoq2, those were the first thing I did once my Nexus 7 was set up.
Eclipse used to recognize my husbands Android (Vizio VTAB1080) and then stopped. So, the issue is with my Windows somehow. One computer never saw any device, the other stopped (I have a 'work' PC and a 'home' PC, plus the travel laptop, the Mac box and my Linux box, and my hubby has a bunch of machines as well).
Since I have my computers set up as web servers (for testing and development and personal use), I just made a simple download page on one of the domains and copied the built apks there. It works.
Cheers,
