USB Serial Number

Type: Automated Test

Overview

The USB Serial Number test verifies that the serial number on the test device is unique.

Details

Universal Serial Bus (USB) device serial numbers are optional, but if they are implemented, they are required to be unique.

If the serial number feature is implemented, the test setup requires two identical devices with different serial numbers in order to pass this test.

If the serial number is not implemented, this test is skipped and is reported as pass.

Note  For embedded USB devices (for example, laptop devices) where it is impossible to meet the external hub connectivity requirement, you must follow the following steps:

  1. Select the job USB Device Framework (CV) (Manual) from Available jobs pane in the Device Console.
  2. Click the Add Selected button on the Device Console. The selected job shows up in the bottom pane.
  3. Select this job from the bottom pane. Right-click on it and select Edit Parameters
  4. You will see the Parameter Edit window open, with parameters listed on the left and their values on the right.
  5. Change this value of IsEmbeddedUSBDevice parameter from FALSE to TRUE.
  6. Click the Schedule Jobs button on the Device Console to run this job.

Note  If the device goes into selective suspend rapidly, then you may have to disable the power management option in the device manager for the hub to which the device is connected.
