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