Hi all I am now writing a gadget controller driver, but face some problem when the driver still in enumeration. Here is what i get from the host, it is very strange that my hardware only support 2 configuration, so don't know why can't set config #3. Also, my hardware auto reply set configuration request to the host without software control, this confuses some gadget driver(at least file_storage) that it does not config completely. Could i just add a self-made set configuration request when gadget driver register. It is difficult to debug before bus enumeration, Is there any method to debug more efficient?
