Take note libusb does not support audio driver. You have to use WinUSB driver or other supported driver. If you have control of the device FW, I will suggest you create one extra interface with just the control endpoint, then you can use WinUSB driver for that interface and you can use libusb. -- Xiaofan _______________________________________________ pyusb-users mailing list pyusb-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/pyusb-users
