On the embedded side (remote node) my device is using a TI chip set and I
do get an interrupt on the remote node when the isochronous transfer is
initiated by the PC (whether Windows or Liunx). This is used to tell the
chip to start moving data out on the isochronous channel.

I hadn't thought of a timeout, that's a good idea since I do have a known
minimum data rate on the channel.

Thanks for the help,
