Hi,
To synchronize the isochronous in and out pipe of a USB sound device I would
like to use implicit feedback: the source data rate (A/D or DIR) has the same
bitrate as the sink so no explicit feedback to throttle the USB out stream
should
be needed. In the USB2.0 spec page 75 (5.12.4.3) it says this is done
implementation
dependent. Can anyone point me to some links / info how this is done/can be
done?
Or is it as simple as writing the same number/size packages as have been read?
Regards,
Bart
