STRUCT USB_EP(9) Kernel Mode Gadget API STRUCT USB_EP(9)NAMEstruct_usb_ep - device side representation of USB endpoint
SYNOPSIS
struct usb_ep {
void * driver_data;
const char * name;
const struct usb_ep_ops * ops;
struct list_head ep_list;
unsigned maxpacket:16;
};
MEMBERS
driver_data
for use by the gadget driver. all other fields are read-only to
gadget drivers.
name
identifier for the endpoint, such as “ep-a” or “ep9in-bulk”
ops
Function pointers used to access hardware-specific operations.
ep_list
the gadget´s ep_list holds all of its endpoints
maxpacket
The maximum packet size used on this endpoint. The initial value
can sometimes be reduced (hardware allowing), according to the
endpoint descriptor used to configure the endpoint.
DESCRIPTION
the bus controller driver lists all the general purpose endpoints in
gadget->ep_list. the control endpoint (gadget->ep0) is not in that
list, and is accessed only in response to a driver setup callback.
