MEMBERS

21       desc
22           descriptor for this endpoint, wMaxPacketSize in native byteorder
23
24       ss_ep_comp
25           SuperSpeed companion descriptor for this endpoint
26
27       urb_list
28           urbs queued to this endpoint; maintained by usbcore
29
30       hcpriv
31           for use by HCD; typically holds hardware dma queue head (QH) with
32           one or more transfer descriptors (TDs) per urb
33
34       ep_dev
35           ep_device for sysfs info
36
37       extra
38           descriptors following this endpoint in the configuration
39
40       extralen
41           how many bytes of “extra” are valid
42
43       enabled
44           URBs may be submitted to this endpoint
