usbipd(8) USB/IP server daemon


usbipd [options]


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. The clients authorised to connect may be configured as documented in hosts_access(5).


-4, --ipv4
Bind to IPv4. Default is both.

-6, --ipv6
Bind to IPv6. Default is both.

-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/

-tPORT, --tcp-port PORT

Listen on TCP/IP port PORT.

-h, --help

Print the program help message and exit.

-v, --version
Show version.


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