USB gadget mode in laptop

Hello All, I was looking into USB gadget mode to work on my laptop. One simple basic doubt I have is how do I know whether my USB controller supports gadget mode ? If it supports which module do I need to modprobe ? Found gadget directory here /lib/modules/4.6.4-1-ARCH/kernel/drivers/usb/gadget , but not getting which one to load. Any pointer where I can learn about this more ? Thanks SusanooTux
