Howto Setup USB CDC 5 channels?

taraben

Hello in my project I need a USB CDC combo device with 5 CDC channels. I use STM32F407.

How can I do that?

In the CubeMX I can setup 5 "interfaces"/"configurations". But in my system appears only 1 CDC channel.

But there are more than 1 interface registered.

I would have expected 5 CDCs.

Any pointer howto continue?

( I know that the example cdc driver does not multi instances and I have to advance)

Thanks in advance, Adib.

on linux I get:

lsusb -d 483: -v|grep EP
