This does not works, many drivers will check the driver->speed, ie in
musg_gadget.c

Uh? Not sure what you mean here. Note that driver above is not the
same
structure as driver below. composite_driver is what musb_gadget_start()
will get.

For example I got -EINVAL in musb_gadget_start in case
composite_driver.speed = USB_SPEED_SUPER
For anything other then g_ether and g_zero, the speed should be set to
USB_SPEED_HIGH. Unless this is somehow related to what Alan said about
this code.
the driver param is the composite_driver in composite.c, isn't it?
Yes.

struct usb_gadget_driver *driver)

struct musb *musb = gadget_to_musb(g);
