NAME
       struct_usb_host_endpoint - host-side endpoint descriptor and queue

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

MEMBERS
       desc
           descriptor for this endpoint, wMaxPacketSize in native byteorder

       ss_ep_comp
           SuperSpeed companion descriptor for this endpoint

       ssp_isoc_ep_comp
           SuperSpeedPlus isoc companion descriptor for this endpoint

       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

       extra
           descriptors following this endpoint in the configuration

       extralen
           how many bytes of “extra” are valid

       enabled
           URBs may be submitted to this endpoint

       streams
           number of USB-3 streams allocated on the endpoint

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