Hello @Zhou JianQiang,

I think there is a dependency with USBX, have you enabled that?

Hi @Zhou JianQiang ,

USBX Audio 1.0/2.0 class support with cubemx x-cube-azrtos packs is only availble with H7 pack in last release.

You can generate the skeleton of your prject with L4 pack, then use H7 pack to generate app files (init and descriptor files) and include them in your prject manually.

Hi @Mohamed_AYED ：

Thank you for your advice.

Yes, I know the USBX Audio 1.0/2.0 class of H7 is ok.

But I still want to confirm with ST official.
