USB_HOST_ENDP(9) 				  Host-Side Data Types and Macro				   STRUCT USB_HOST_ENDP(9)

NAME
       struct_usb_host_endpoint - host-side endpoint descriptor and queue

SYNOPSIS
       struct usb_host_endpoint {
	 struct usb_endpoint_descriptor desc;
	 struct list_head urb_list;
	 void * hcpriv;
	 struct ep_device * ep_dev;
	 struct usb_host_ss_ep_comp * ss_ep_comp;
	 unsigned char * extra;
	 int extralen;
	 int enabled;
       };

MEMBERS
       desc
	   descriptor for this endpoint, wMaxPacketSize in native byteorder

       urb_list
	   urbs queued to this endpoint; maintained by usbcore

       hcpriv
	   for use by HCD; typically holds hardware dma queue head (QH) with one or more transfer descriptors (TDs) per urb

       ep_dev
	   ep_device for sysfs info

       ss_ep_comp
	   companion descriptor information for this endpoint

       extra
	   descriptors following this endpoint in the configuration

       extralen
	   how many bytes of "extra" are valid

       enabled
	   URBs may be submitted to this endpoint

DESCRIPTION
       USB requests are always queued to a given endpoint, identified by a descriptor within an active interface in a given USB configuration.
