Here we done :)
After a long pause I coming back with the amp projet and restart trying to make usb hid working.
And usb hid works :) what a joy to see my mouse pointer moving when I plug the USB in the PC!
The solution (not pround to post it but...)
In my makefile the TARGET was wrong, then the custom xn file with following line wasn't used to build (instead it was default xn file in makefile XFU208-256-TQ64-C10 which ins't working for usb hid...)
Here my custom hid with the right line (on bold which specify USB clock) which is working:

Then the trick: when you aren't finding the bug, just give up for a time and come back with fresh mind is still right in 2020 :)
Now time to serious business with audio class and porting audio code to my custom board.
mon2: again a lot of thanks to you.
