hi~ all
I have developed USB firmware.
It send audio stream from imbedded board to PC.
But I need PC to send some short packet to imbedded board.
I want USB device operate as HID and audio(isochronous IN) at the same 
time.
And, I can not develop Windows device driver.
So, I need to use some profile supported by windows default driver.
Can I get some usefull USB prifile??

Thanks~!
