The USB driver should work fine, I have an Efika (MPC5200B) with that exact USB controller and revision and it's just fine and dandy. We also used to ship Via-based USB cards in the Pegasos Open Desktop Workstation (using Marvell Discovery II northbridge). The major difference here would be that PCI tree entries were created by a real OF implementation so may have reflected some hardware better; it is dynamically created on boot to a certain point, rather than a fixed device tree which may contain some "errors". There seems to be a lot less data in our tree... I can't vouch for the correctness of your tree, though, or tell you what might be wrong (looks fine as far as I am concerned, but what do I know? :) -- Matt Sealey Genesi, Manager, Developer Relations
