Greetings everybody, I have been trying to acquire data from my Sound Blaster audio device through USB using libusb library. Have been trying to implement isochronous communication mode and having an error related to busy device, errno = 16. While I was searching in the web, I see when asound.state file is running, similar problems might arise. I am not experienced that much in either Linux and libusb. That is why, wanted to ask this in this forum. If you could show me a way to solve my problem, I would be glad. Thanks in advance
