Default MZ602 drivers

I'm running Windows 8 64-bit on my laptop, trying to install xoom drivers. I installed the latest version of Motorola Device Software Update. It asks me to put my device into MTP mode. Windows recognizes it. It even installs MTP drivers. Motorola won't have it though. Tried with and without USB debugging. Nothing is working. Any ideas?

-camera back to mtp
-different cable
-different port

none of those worked
