I'm trying to get my platform support working in mainline 2.6.37. I have a MPC8379 which is working well in 2.6.32.

When I just move my platform to the new kernel, everything works except for USB host mode. Nothing special about my platform - it's pretty much like the FSL eval boards (as far as this part is concerned). I can see it start up, claim to power up the internal hub, but I never see the state change interrupt from the hub.

Are there any known gotchas here? Any ideas?

Thanks
