Why would a laptop support gadget mode? A USB "gadget" is USB hardware
that acts like a device (keyboard, mouse, storage, etc.). Laptops
almost never have that type of hardware in them as they are USB "hosts"
and control USB devices.
You can buy PCI devices that act as USB gadgets, and that's used for
development of systems, and many smaller devices (phone, tablets, etc.)
have hardware that can act in both host and gadget mode. But again, you
need special hardware for this, something that I have never seen built
into a laptop.
So, sorry, I don't think you will be able to do this.
