+Background
+==========
+
+Bulk endpoint streams were added in the USB 3.0 specification.  Streams allow a
+device driver to overload a bulk endpoint so that multiple transfers can be
+queued at once.
+
+Streams are defined in sections 4.4.6.4 and 8.12.1.4 of the Universal Serial Bus
+3.0 specification at http://www.usb.org/developers/docs/  The USB Attached SCSI
+Protocol, which uses streams to queue multiple SCSI commands, can be found on
+the T10 website (http://t10.org/).
+
+
+Device-side implications
+========================
+
+Once a buffer has been queued to a stream ring, the device is notified (through
+an out-of-band mechanism on another endpoint) that data is ready for that stream
+ID.  The device then tells the host which "stream" it wants to start.  The host
+can also initiate a transfer on a stream without the device asking, but the
+device can refuse that transfer.  Devices can switch between streams at any
+time.
+
+
+Driver implications
+===================
+
+int usb_alloc_streams(struct usb_interface *interface,
+		struct usb_host_endpoint **eps, unsigned int num_eps,
+		unsigned int num_streams, gfp_t mem_flags);
+
+Device drivers will call this API to request that the host controller driver
+allocate memory so the driver can use up to num_streams stream IDs.  They must
+pass an array of usb_host_endpoints that need to be setup with similar stream
+IDs.  This is to ensure that a UASP driver will be able to use the same stream
+ID for the bulk IN and OUT endpoints used in a Bi-directional command sequence.
+
+The return value is an error condition (if one of the endpoints doesn't support
+streams, or the xHCI driver ran out of memory), or the number of streams the
+host controller allocated for this endpoint.  The xHCI host controller hardware
+declares how many stream IDs it can support, and each bulk endpoint on a
+SuperSpeed device will say how many stream IDs it can handle.  Therefore,
+drivers should be able to deal with being allocated less stream IDs than they
+requested.
+
+Do NOT call this function if you have URBs enqueued for any of the endpoints
+passed in as arguments.  Do not call this function to request less than two
+streams.
+
+Drivers will only be allowed to call this API once for the same endpoint
+without calling usb_free_streams().  This is a simplification for the xHCI host
+controller driver, and may change in the future.
+
+
+Picking new Stream IDs to use
+============================
+
+Stream ID 0 is reserved, and should not be used to communicate with devices.  If
+usb_alloc_streams() returns with a value of N, you may use streams 1 though N.
+To queue an URB for a specific stream, set the urb->stream_id value.  If the
+endpoint does not support streams, an error will be returned.
+
+Note that new API to choose the next stream ID will have to be added if the xHCI
+driver supports secondary stream IDs.
+
+
+Clean up
+========
+
+If a driver wishes to stop using streams to communicate with the device, it
+should call
+
+void usb_free_streams(struct usb_interface *interface,
+		struct usb_host_endpoint **eps, unsigned int num_eps,
+		gfp_t mem_flags);
+
+All stream IDs will be deallocated when the driver releases the interface, to
+ensure that drivers that don't support streams will be able to use the endpoint.

+Introduction
+
+	The HID Gadget driver provides emulation of USB Human Interface
+	Devices (HID). The basic HID handling is done in the kernel,
+	and HID reports can be sent/received through I/O on the
+	/dev/hidgX character devices.
+
+	For more details about HID, see the developer page on
+	http://www.usb.org/developers/hidpage/
+
+Configuration
+
+	g_hid is a platform driver, so to use it you need to add
+	struct platform_device(s) to your platform code defining the
+	HID function descriptors you want to use - E.G. something
+	like:
+
+#include <linux/platform_device.h>

+
+	HID reports can be sent/received using read/write on the
+	/dev/hidgX character devices. See below for an example program
+	to do this.
+
+	hid_gadget_test is a small interactive program to test the HID
+ 	gadget driver. To use, point it at a hidg device and set the
+ 	device type (keyboard / mouse / joystick) - E.G.:
+
+		# hid_gadget_test /dev/hidg0 keyboard
+
+	You are now in the prompt of hid_gadget_test. You can type any
+	combination of options and values. Available options and
+	values are listed at program start. In keyboard mode you can
+	send up to six values.
+
+	For example type: g i s t r --left-shift
+
+	Hit return and the corresponding report will be sent by the
+	HID gadget.
+
+	Another interesting example is the caps lock test. Type
+	-–caps-lock and hit return. A report is then sent by the
+	gadget and you should receive the host answer, corresponding
+	to the caps lock LED status.
+
+		--caps-lock
+		recv report:2
+
+	With this command:
+
+		# hid_gadget_test /dev/hidg1 mouse
+
+	You can test the mouse emulation. Values are two signed numbers.
