Type: Automated Test

Overview

The USB Address Description Test runs a number of individual tests that verify various attributes and operations used by the function-specific portions of the test device. The tests also verify communications from the device through the bus interface to the host. The USB Address Description Test is based on the USBCV compliance test tool provided by the USB Implementers Forum, Inc. (USB-IF).

A USB device must respond correctly to all possible USB device addresses from 0 through 127. This test verifies that devices can respond correctly at their assigned addresses and that they do not respond at any other address.

Details

The test includes the following parts:

Setup

This test fails if the test device is more than one hub deep. Please note that test should be run with a device connected directly to a root hub of the system or with a USB-IF certified hub with less than seven ports.

Initialization

  • Select device to test

  • Open handle to host controller

  • Gather initial information:

    • Device descriptor
    • Configuration descriptor
    • String descriptors (if supported by device and test)

Address test #1 (repeat for all addresses)

  • Reset device port

  • Get descriptors (device, configuration, string) from address 0

  • Set device address (next address value not in use)

  • Get descriptors using address 0 (device should not respond)

  • Get descriptors using new address (device should respond)

  • Compare descriptors to initial information

Address test #2 (repeat for all addresses)

  • Reset device port (first time only)

  • Set address (next address value not in use)

  • Get descriptors from previous address (device should not respond)

  • Get descriptors from new address (device should respond)

  • Compare descriptors to initial information

Result

For success, a device must always respond with valid device, configuration, and string descriptors while not responding at its previous device address. Any failure is a test failure.

Results Interpretation

The test fails if:

  • Any standard device request is not properly handled by the device being tested.

  • Any standard device request does not meet the response time requirements as defined in the USB specification.

  • A device fails to respond to a request at its currently assigned address.

  • A device responds at an address other than its currently assigned address
