Existing audio class driver in MAC x doesn't support the USB 2.0 Audio device.
 
so,
 
1.can i get the support for USB 2.0  Audio device from existing audio class driver if i will change the frame transferring rate ?
 
 
 
2.is frame rate the only difference between the USB2.0 and USB 1.1? or any other entity influenced Between the 2.0&1.1. 
 
 
 
3. is there any other options for getting USB 2.0 support from existing audio class driver?
 
 
 
4.can i write the sound component for getting Audio frames? is it better option?
 
 
5. This is USB 2.0 device. if i will make sound component for USB 1.1 driver, will my device supports that component?
 
6. Actually my device is having separate(audio and video) interface.
           
       Can i get the audio and video frames parallely? I thing USB connector is having one or two data lines. 
 
is it possible to getting parallel data from  usb connector?
 
like
 
Video--->
------------------------------------------------------------------------ frames
Audio----->
----------------------------------------------------------------------frames
 
or  sequentially like
 
video.........audio..........video..............audio.......frames
 
 
 
7.If any one  involving in the core audio development, Suggest me what are the areas i will make changes in existing audio class driver to get the support of
USB 2.0  if it is possible.
 
 
 
 
 
Plz suggest me.
