FSL USB in 2.6.37

From: Gary Thomas <hidden>
Date: 2011-02-15 17:47:21 

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
