[Venue 7/8] USB OTG Confirmed
Just letting you know, I can confirm that USB OTG works out of the box for these tablets, been using my USB key perfectly fine. This feature can be particularly useful if you have a USB hard drive or any USB devices you want to connect. The wired XBOX 360 controller also works but need to be remapped to work apparently.
Attached are some screenshots.
