Hi Anatolij,

I tracked the problem down to a change made in September, which
happens to be yours:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=126512e3f274802ca65ebeca8660237f0361ad48

When I roll this back, everything works fine again.

First of all, I noticed that fsl-mph-dr-of.c isn't even compiling for
me (even though I have the option enabled in my .config), because it's
been placed in "usb/host/", and I'm only using device/gadget-mode USB.

I edited the top-level Makefile to just force it into "usb/host/", and
that makes sure that your driver gets built (and it's probed just fine
at runtime).  But that still didn't solve the problem - as before,
fsl_udc_probe() is never being called.

Did you test this change in device mode?  I'm wondering if there's
something different about my configuration that prevents it from
working.  My config is uploaded here if it helps:

Thanks!
