Vendor class with ISO endpoints

[MikeEmbedded]

Hi.

I successfully run Vendor class device on USB HS using STM32H723 + USB3320.

Vendor class has BULK endpoints and it works fine.

But if I change descriptor and some code to have Vendor class with ISO endpoints then it enumerates successfully but there is no any data received(tud_vendor_rx_cb is not called when I send some data from PC).

So, is there any example or any possibility to use Vendor device class with ISO endpoints?

Thanks!
