7

SYNOPSIS

9       int usb_find_common_endpoints(struct usb_host_interface * alt,
10                                     struct usb_endpoint_descriptor ** bulk_in,
11                                     struct usb_endpoint_descriptor ** bulk_out,
12                                     struct usb_endpoint_descriptor ** int_in,
13                                     struct usb_endpoint_descriptor ** int_out);

ARGUMENTS

16       alt
17           alternate setting to search
18
19       bulk_in
20           pointer to descriptor pointer, or NULL
21
22       bulk_out
23           pointer to descriptor pointer, or NULL
24
25       int_in
26           pointer to descriptor pointer, or NULL
27
28       int_out
29           pointer to descriptor pointer, or NULL
30

DESCRIPTION

32       Search the alternate setting's endpoint descriptors for the first
33       bulk-in, bulk-out, interrupt-in and interrupt-out endpoints and return
34       them in the provided pointers (unless they are NULL).
35
36       If a requested endpoint is not found, the corresponding pointer is set
37       to NULL.
38

RETURN

40       Zero if all requested descriptors were found, or -ENXIO otherwise.
