Also the issue is fixed on my linux-2.6.35.y branch applying the patch and cherry-picking f11d893de444965dfd3e55f726533ae1df5c6471 usb: musb: support ISO high bandwidth for gadget mode b0fca50f5a94a268ed02cfddf44448051ed9343f usb gadget: don't save bind callback in struct usb_gadget_driver Cheers, Enric -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
