usbipd - USB/IP server daemon

NAME SYNOPSIS DESCRIPTION OPTIONS LIMITATIONS EXAMPLES SEE ALSO

DESCRIPTION

usbipd provides USB/IP clients access to exported USB devices.

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

The daemon accepts connections from USB/IP clients on TCP port 3240 by default.

OPTIONS

−4, −−ipv4

Bind to IPv4. Default is both.

−6, −−ipv6

Bind to IPv6. Default is both.

−e, −−device

Run in device mode. Rather than drive an attached device, create a virtual UDC to bind gadgets to.

−D, −−daemon

Run as a daemon process.

−d, −−debug

Print debugging information.

−PFILE, −−pid FILE

Write process id to FILE.
If no FILE specified, use /var/run/usbipd.pid

−tPORT, −−tcp−port PORT

Listen on TCP/IP port PORT.

−h, −−help

Print the program help message and exit.

−v, −−version

Show version.

LIMITATIONS

usbipd offers no authentication or authorization for USB/IP. Any USB/IP client can connect and use exported devices.

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.
