I used lufa AudioInput sample code on an arduino leonardo board.
I changed code to send consecutive incremental 8 bit data to usb port of a windows 7 computer, but when I get data from sound card I find that data is filtered by standard sound driver of windows.
I also changed the endpoint size from 256 bytes to 288 bytes based on my requirements.
I need to send my own data over isochrounous sound card endpoint of LUFA.
But I do not know how to get raw data from sound card in windows.
If you have any idea please let me know.
could we get raw data from sound card?
By raw data I mean the exact data that produced by usb device and is not filtered by windows driver.
In this way we have the chance of getting a lot of data in real time from USB 1.1 devices of ATMEL corporation.
