Is it possible that this reference to the file is caused by the poll() call in the ep0_thread? I need to simulate a "device disconnect" to the USB Host, for that I currently do the following steps: 1) stop_io() - stop the data endpoints ep1_in, ep1_out with close() 2) stop the ep0_thread 3) close the ep0 endpoint with close() 4) wait one second 5) restart ep0_thread Normally this method works, but under some circumstances, it doesn't (dev_release is missing) What is the appropriate method to close all references to the ep-file descriptors? Is there a way to debug/see what reference causes the not-releasing the device? I'm sorry for these questions, but anyway I hope you can help me out.
