| [Overview] |
| USB/IP protocol allows to pass USB device from server to client over the |
| network. Server is a machine which provides (shares) a USB device. Client is |
| a machine which uses USB device provided by server over the network. |
| The USB device may be either physical device connected to a server or |
| software entity created on a server using USB gadget subsystem. |
| Whole project consists of four parts: |
| |
| - usbip-vhci |
| A client side kernel module which provides a virtual USB Host Controller |
| and allows to import a USB device from a remote machine. |
| |
| - usbip-host (stub driver) |
| A server side module which provides a USB device driver which can be |
| bound to a physical USB device to make it exportable. |
| |
| - usbip-vudc |
| A server side module which provides a virtual USB Device Controller and allows |
| to export a USB device created using USB Gadget Subsystem. |
| |
| - usbip-utils |
| A set of userspace tools used to handle connection and management. |
| Used on both sides. |
| |
| [Requirements] |
| - USB/IP device drivers |
| Found in the drivers/usb/usbip/ directory of the Linux kernel tree. |
| |
| - 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] |
| On a server side there are two entities which can be shared. |
| First of them is physical usb device connected to the machine. |
| To make it available below steps should be executed: |
| |
| 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. |
| |
| Second of shareable entities is USB Gadget created using USB Gadget Subsystem |
| on a server machine. To make it available below steps should be executed: |
| |
| server:# (Create your USB gadget) |
| - Currently the most preferable way of creating a new USB gadget |
| is ConfigFS Composite Gadget. Please refer to its documentation |
| for details. |
| - See vudc_server_example.sh for a short example of USB gadget creation |
| |
| server:# insmod usbip-core.ko |
| server:# insmod usbip-vudc.ko |
| - To create more than one instance of vudc use num module param |
| |
| server:# (Bind gadget to one of available vudc) |
| - Assign your new gadget to USB/IP UDC |
| - Using ConfigFS interface you may do this simply by: |
| server:# cd /sys/kernel/config/usb_gadget/<gadget_name> |
| server:# echo "usbip-vudc.0" > UDC |
| |
| server:# usbipd -D --device |
| - Start usbip daemon. |
| |
| To attach new device to client machine below commands should be used: |
| |
| 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. |
| - When using vudc on a server side busid is really vudc instance name. |
| For example: usbip-vudc.0 |
| |
| 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 |
| Exportable USB devices |

| /sys/class/scsi_device/0:0:0:0/device |
| /sys/class/scsi_host/host0/device |
| /sys/block/sda/device |
| |
| Detach the imported device: |
| |

| 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. |
| - Target USB gadget must be bound to vudc |
| (using USB gadget susbsys, not usbip bind command) |
| - Shutdown firewall. |
| - usbip now uses TCP port 3240. |
| - Disable SELinux. |
| - Check the kernel and daemon messages. |
