The problem is that adb devices shows no devices, and Eclipse also (not surprisingly) also does not offer the Nexus 7 as a hardware device to run an app on. This also proves the device is in USB debugging mode, because if it is not it shows up in Windows under "Portable Devices" / "Nexus 7".
#VIA USB HOST CONTROLLER WINDOWS 7 DRIVER#
When the Nexus 7 is connected, the device shows up in the Windows Device Manager as "Android Phone" / "Android Composite ADB Device", with the properties showing driver version 6.0.0.0, so the correct driver is installed and working.
#VIA USB HOST CONTROLLER WINDOWS 7 ANDROID#
I have done the obvious - the USB driver was installed from the latest Android SDK, and USB debugging was turned on in the tablet.
