Linus Torvalds e7cf773d43 USB patches for 3.19-rc1
Here's the big set of USB and PHY patches for 3.19-rc1.
 
 The normal churn in the USB gadget area is in here, as well as xhci and
 other individual USB driver updates.  The PHY tree is also in here, as
 there were dependancies on the USB tree.
 
 All of these have been in linux-next.

[Requirements]
    - USB/IP device drivers
	Found in the staging directory of the Linux kernel.

    - libudev >= 2.0
	libudev library

    - libwrap0-dev
	tcp wrapper library

    - gcc >= 4.0

    - libtool, automake >= 1.9, autoconf >= 2.5.0, pkg-config

[Optional]
    - hwdata
        Contains USB device identification data.


[Install]
    0. Generate configuration scripts.
	$ ./autogen.sh

    1. Compile & install the userspace utilities.
	$ ./configure [--with-tcp-wrappers=no] [--with-usbids-dir=<dir>]
	$ make install

    2. Compile & install USB/IP drivers.


[Usage]
    server:# (Physically attach your USB device.)

    server:# insmod usbip-core.ko
    server:# insmod usbip-host.ko

    server:# usbipd -D
	- Start usbip daemon.

    server:# usbip list -l
	- List driver assignments for USB devices.

    server:# usbip bind --busid 1-2
	- Bind usbip-host.ko to the device with busid 1-2.
	- The USB device 1-2 is now exportable to other hosts!
	- Use `usbip unbind --busid 1-2' to stop exporting the device.

    client:# insmod usbip-core.ko
    client:# insmod vhci-hcd.ko

    client:# usbip list --remote <host>
	- List exported USB devices on the <host>.

    client:# usbip attach --remote <host> --busid 1-2
	- Connect the remote USB device.

    client:# usbip port
	- Show virtual port status.

    client:# usbip detach --port <port>
	- Detach the USB device.


[Example]
---------------------------
	SERVER SIDE
---------------------------
Physically attach your USB devices to this host.

    trois:# insmod path/to/usbip-core.ko
    trois:# insmod path/to/usbip-host.ko
    trois:# usbipd -D

In another terminal, let's look up what USB devices are physically
attached to this host.

    trois:# usbip list -l
    Local USB devices
    =================
     - busid 1-1 (05a9:a511)
	     1-1:1.0 -> ov511

     - busid 3-2 (0711:0902)
	     3-2:1.0 -> none

     - busid 3-3.1 (08bb:2702)
	     3-3.1:1.0 -> snd-usb-audio
	     3-3.1:1.1 -> snd-usb-audio

     - busid 3-3.2 (04bb:0206)
	     3-3.2:1.0 -> usb-storage

     - busid 3-3 (0409:0058)
	     3-3:1.0 -> hub

     - busid 4-1 (046d:08b2)
	     4-1:1.0 -> none
	     4-1:1.1 -> none
	     4-1:1.2 -> none

     - busid 5-2 (058f:9254)
	     5-2:1.0 -> hub

A USB storage device of busid 3-3.2 is now bound to the usb-storage
driver. To export this device, we first mark the device as
"exportable"; the device is bound to the usbip-host driver. Please
remember you can not export a USB hub.

Mark the device of busid 3-3.2 as exportable:

    trois:# usbip --debug bind --busid 3-3.2
    ...
    usbip debug: usbip_bind.c:162:[unbind_other] 3-3.2:1.0 -> usb-storage
    ...
    bind device on busid 3-3.2: complete

    trois:# usbip list -l
    Local USB devices
    =================
    ...

     - busid 3-3.2 (04bb:0206)
	     3-3.2:1.0 -> usbip-host
    ...

---------------------------
	CLIENT SIDE
---------------------------
First, let's list available remote devices that are marked as
exportable on the host.

    deux:# insmod path/to/usbip-core.ko
    deux:# insmod path/to/vhci-hcd.ko

    deux:# usbip list --remote 10.0.0.3

Attach a remote USB device:

    deux:# usbip attach --remote 10.0.0.3 --busid 1-1
    port 0 attached

Show the devices attached to this client:

    deux:# usbip port
    Port 00: <Port in Use> at Full Speed(12Mbps)
	   Prolific Technology, Inc. : unknown product (067b:3507)
	   6-1 -> usbip://10.0.0.3:3240/1-1  (remote bus/dev 001/004)
	   6-1:1.0 used by usb-storage
			  /sys/class/scsi_device/0:0:0:0/device
			  /sys/class/scsi_host/host0/device
			  /sys/block/sda/device

Detach the imported device:

    deux:# usbip detach --port 0
    port 0 detached


[Checklist]
    - See 'Debug Tips' on the project wiki.
	- http://usbip.wiki.sourceforge.net/how-to-debug-usbip
    - usbip-host.ko must be bound to the target device.
	- See /proc/bus/usb/devices and find "Driver=..." lines of the device.
    - Shutdown firewall.
	- usbip now uses TCP port 3240.
    - Disable SELinux.
    - Check the kernel and daemon messages.
