Testing over USPIP in native_posix
***********************************

A virtual USB controller implemented through USBIP might be used to test the USB
Device stack. Follow the general build procedure to build the USB sample for
the native_posix configuration.

Run built sample with:

.. code-block:: console

   west build -t run

In a terminal window, run the following command to list USB devices:

.. code-block:: console

   $ usbip list -r localhost
   Exportable USB devices
   ======================
    - 127.0.0.1
           1-1: unknown vendor : unknown product (2fe3:0100)
              : /sys/devices/pci0000:00/0000:00:01.2/usb1/1-1
              : (Defined at Interface level) (00/00/00)
              :  0 - Vendor Specific Class / unknown subclass / unknown protocol (ff/00/00)

In a terminal window, run the following command to attach the USB device:

.. code-block:: console

   $ sudo usbip attach -r localhost -b 1-1

The USB device should be connected to your Linux host, and verified with the following commands:

.. code-block:: console

   $ sudo usbip port
