I managed to discover a Cat6504, but it's shown as unknown device (ciscoProducts.657), what's wrong?
When i opened the cisco view, I managed to get the view as a Cat6504.
Yes. Every MDF contains all of the previous device updates. The same is true for the CM 4.0.9 update. It contains all the device support and bug fixes from CM 4.0.7 and 4.0.8.
