A Dbulk-streams.rst1 USB bulk streams
7 Bulk endpoint streams were added in the USB 3.0 specification. Streams allow a

24 device can refuse that transfer. Devices can switch between streams at any
44 streams, or the xHCI driver ran out of memory), or the number of streams the
53 streams.
64 usb_alloc_streams() returns with a value of N, you may use streams 1 though N.
66 endpoint does not support streams, an error will be returned.
75 If a driver wishes to stop using streams to communicate with the device, it
83 ensure that drivers that don't support streams will be able to use the endpoint.
