[android-developers] Re: Nexus 7 not visible to adb over usb (WIndows 7 x64, up to date Jelly Bean sdk)

I'm happy to answer my own question.

1) Can't blame Windows!

2) When the Nexus 7 is plugged in there is a persistent notification that indicates "CONNECT AS / Media Device (MTP)". In this state adb devices will not show the Nexus. Not exactly obvious why, but I you select the second option "Camera (PTP)" the device is available for debugging. This choice is persistent, and I'm guessing that with a band new device it will connect as MTP until told otherwise.

Trying to force feed myself Windows to build character, and the seemly trivial thing of plugging in a Nexus 7 to a Dell xps 15z Tand debugging a "hello world" app on it from Eclipse Juno with the latest ADT plugin has me stumped.

Developer options were turned on, and USB debugging enabled.

The device just does not show up, not in Eclipse, or in "adb devices".

The first time I had not installed the USB driver from the sdk. In this case the Nexus 7 shows up in the WIndows devices under "Portable Devices" and a filesystem can be browsed from Windows.

Next I installed the google USB driver. Now the Nexus 7 shows up in the Windows devices as "Android Phone"/"Android composite ADB interface", and at that point I thought I was moments away from looking at "Hello World" and moving on to something interesting, but wait, there's more, adb remained blind to the Nexus7.

Any ideas, or suggestions for debugging this problem would be appreciated...
