I have not read any clear statement about this, but IMHO we should
consider CONFIG_USB_DEVICE obsolete and move to CONFIG_USB_GADGET.

Yes, that is right - there is currently no support for the serial gadget.

This is very interesting !

There is a lot of boards using  CONFIG_USB_DEVICE. We cannot drop then
CONFIG_USB_DEVICE, but new boards must use the new interface.
