Dear All, 
 
I develop a USB audio device and I need to use a ADPCM data format.   
I just need to know if it is possible to use this format without to
write a custom driver (maybe just using usbaudio.sys and Ks.sys). 
Which are the real datas to send from the USB chip to windows  ?  
 
Thanks in advance
Raph
