Answer 1

I had faced two issues:

1. Nexus 7 not visible to eclipse/adb when connected over usb on windows 7 64-bit using latest Jelly Bean sdk
2. It was not showing in the 'My Computer' >> 'Portable Devices' list.

Ultimately, I found that it is an issue with the driver. Steps to resolve the issue - Open Device Manager, Uninstall the current driver (along with delete option set to yes), disconnect the device, reconnect it again, let windows install the default driver it wants, and then installed the google sdk driver again. It worked this time.

Above tells me that there is some issue with default driver and therefore, you have to delete it and re-install it. Now, it is visible in eclipse/adb and also showing in 'My Computer' also.

Download universal windows adb driver(Koush). Worked for me for windows pc's. http://www.koushikdutta.com/post/universal-adb-driver

Answer 3

I am using Windows 8 and the only thing that worked for me was the Nexus Root Toolkit 1.6.3 where I done the Full driver configuration Guide ... but I didn't follow the instructions there I went to step 2 and only installed the Signed drivers.

Another option is if windows updates are turned totally off on your PC. In this case even if you download the USB driver & try update it manually as described above it will not work. The only way in this case is enabling windows updating drivers automatically. Once you enabled this, remove the non-working driver from device manager & connect you tablet to the PC via USB cable. The drivers will be automatically downloaded & installed by Windows. This way worked on my Windows 7 PC.

Hey I found a solution to this via mkh at https://groups.google.com/forum/?fromgroups=#!topic/android-developers/0-RzE0v-G3k

Try this (as quoted from the above source)

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

Install Google usb driver from SDK Manager. Later go to Device Manager, under "Other Devices" you'll see "Nexus" with the yellow exclamation mark. Right Click>Update Drivers>Let me choose>Let me pick from device drivers on my computer. Select android-sdk folder and click ok. This solved my problem
