change an USBinterface setting from inactive to active state With JSR80,

JSR80 API

OS linux

Hello. I would like to access at an USBinterface setting (1) of a USB audio device (I use JSR80 library). This setting is not the active setting by default (2 settings : 0 and 1).

How do I do to active this setting. I don't see any method for that. In other API, method exist.

Example :

int usb set interface(struct usb device *dev, int interface,int alternate);

This function activates an alternate setting of a specified interface.

Thanks for your help.
