  • Dear NXP Team:

        Now I am working around  USB Audio Speaker Demo for  Audio Class 2.0 driver with RT1021 in windows10 and android System. But I have some confusion.Firstly. I have tried to modify usb device descriptor to meet usb audio class 2.0.  I successfully get enumeration In windows10 and android.I find there is no  data transferred from host to device in Isochronous out endpoint 
    and control interface can send valid control data.  Is there something other needed to modify?

Hi Paul,

I just checked on mac OS, audio class 2.0 is OK. So, this is the limiation of windows platform, not SDK issue.

Jing
