i am doing some resarch about usb protocol
i began with this http://www.usbmadesimple.co.uk/ums_3.htm
but i have a question:
when a usb driver is build,the type of a node e.g host or device is defined by hardware or software ?
in other words,can a developper change the node type from host to device and vice versa by hacking the driver firmware?
