I try to make a Xmega based microphone for raspberry pi computers based on USB connector.
for that I try to change the Audioinput sample code of lufa.
and change it in a way that it works with my 8MHz xmega128a1u board.
Everything goes well in enumeration phase and windows detects it perfectly as an input microphone device.
But when I want to capture audio, I find that Endpoint_IsINReady() does not return success in timer interrupt.
I attached the project here.
Please give me some hints to get answer from it.
I just try it with windows OS and audacity audio editor.
