[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=]
$ 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
- List exported USB devices on the .

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

client:# usbip port
- Show virtual port status.

client:# usbip detach --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
Exportable USB devices

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

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.
