Hi there. Is there a way to sent control codes to a USB device, without using a specific driver . I would like to try to set latency and output modes of my M-Audio Transit by sending a control code as additional part of the UDEV madfuload firmware initialzation. How can I do something like that? If this works in general I just need to figure out the required control codes. THX for your support Klaus _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
