You should talk to Jean-Baptiste and discover why he needed that entry. Perhaps you haven't yet ran over the limitation. It's also possible that Rock changed their firmware without bothering to update the revision, or Explay patched something. We need to know what exactly is happening. Also, what is "very slow"? 32KB is not that bad, it cannot be very "very". Heck ub always uses that much. Something is "very" fishy here. -- Pete -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
