15 interface
16 alternate setting that includes all endpoints.
17
18 eps
19 array of endpoints that need streams.
20
21 num_eps
22 number of endpoints in the array.
23
24 num_streams
25 number of streams to allocate.
26
27 mem_flags
28 flags hcd should use to allocate memory.

31 Sets up a group of bulk endpoints to have num_streams stream IDs
32 available. Drivers may queue multiple transfers to different stream
33 IDs, which may complete in a different order than they were queued.
