Hello,
We are using six USB audio compsite devices each based on
TI PCM2904 stereo USB audio CODEC. Operating systems is
windows2000/XP and computer has USB1.1 controller. The
problem is that each device requests 15% of USB bandwidth
(device really uses 25% of requested bandwidth). Assuming
that system uses about 20% there are only 5 composite
devices enabled - last device doesnt work...
The question is: Is there any way to reduce USB composite
device requsted bandwidth?
Thank you in advance,
Sergey
