Greetings Rodolfo.

Apologies, for the late response, sometimes I work/sleep without
checking my home mail and missed this for ~ 48 hours.

Umm, *provisionally* this appears not to be a problem for
usbdcore_mpc8xx.c... just having a quick scan of usbdcore_omap1510 I
don't immediately see a way that code could be broken by such a
change... *then again* keep in mind when I was mucking with the
usbtty stuff, I specifically tried *not* to change the order that
things happen in, for fear of breaking other people's - omap stuff.

Perhaps someone using the omap1510 in USB device mode would be in a
better position to make a statement on that.

In this specific instance though we _should_ be safe enough. Even
still when you submit your modifications to the list, I'll ensure I
do a test run from the POV of usbdcore_mpc8xx, just to make sure your
code doesn't break my code !
