.SH NAME
usbipd \- USB/IP server daemon
.SH SYNOPSIS
.B usbipd
[\fIoptions\fR]

.SH DESCRIPTION
.B usbipd
provides USB/IP clients access to exported USB devices.

Devices have to explicitly be exported using
.B usbip bind
before usbipd makes them available to other hosts.

The daemon accepts connections from USB/IP clients
on TCP port 3240 by default.  The clients authorised to connect may be
configured as documented in hosts_access(5).

.SH LIMITATIONS

.B usbipd
offers no authentication or authorization for USB/IP. Any
USB/IP client running on an authorised host can connect and
use exported devices.

.SH EXAMPLES

    server:# modprobe usbip-host

    server:# usbipd -D
        - Start usbip daemon.

    server:# usbip list --local
        - List driver assignments for usb devices.

    server:# usbip bind --busid=1-2
        - Bind usbip-host.ko to the device of busid 1-2.
        - A usb device 1-2 is now exportable to other hosts!
        - Use 'usbip unbind --busid=1-2' when you want to shutdown exporting and use the device locally.

The following example shows the usage of device mode

    server:# modprobe usbip-vudc
        - Use /sys/class/udc/ interface.
        - usbip-host is independent of this module.

    server:# usbipd -e -D
        - Start usbip daemon in device mode.

    server:# modprobe g_mass_storage file=/tmp/tmp.img
        - Bind a gadget to usbip-vudc.
        - in this example, a mass storage gadget is bound.

    server:# usbip list --device
        - List gadgets exported by local usbipd server.

    server:# modprobe -r g_mass_storage
        - Unbind a gadget from usbip-vudc.
        - in this example, the previous mass storage gadget is unbound.
