Hi, I am developping an application with asoundlib. I have a usb audio device that I would like to send usb control transfers, but I did not find a way to do so with asoundlib. More specifically I need to send the GET_MEM (https://www.usb.org/sites/default/files/audio10.pdf, p67 - section 5.2.1.2) request which is an audio class specific usb request. Is there a way to do that with the ALSA Library API? Or do I need to modify the snd-usb-audio driver? Thank you!
