What happened ?

Actually, there is no problem with direct connection. However, when the computer stops making sound, it close the EP after a certain period of time. When I play the sound again, I get the error "hw_data_offset(next_buffer_ptr) <= USB_DPRAM_MAX". I can create this by simply pressing and waiting on the button used for windows to test audio devices.

How to reproduce ?
