About USB gadget drivers
 

Hi,

I want to know about gadget drivers. If i am correct, gadget driver is usb device (function) driver. But I have a question, Do the garget drivers provide emulation corresponding to a device or When the host is pc and we are trying to access some mass storage then does it provide emulation for this? what is use of gadget usb drivers?

Regards

In a nutshell, I would say gadget drivers are a way to make a generic embedded single board computer with a USB peripheral controller behave like some particular USB device like mass storage, ethernet, serial ports etc, keyboard etc.

This is not for PCs or embedded devices that only have a USB host controller.
