Disable Enable Composite Device

  • Article

Note  This content applies to the Windows Logo Kit (WLK). For the latest information using the new Windows Hardware Certification Kit (HCK), see Windows HCK User's Guide on the Windows Hardware Dev Center.

Type: Automated Test

Overview

This test is not required to get a logo (see details in "Running the Test" below). This test script takes Device Instance Path or VID/PID (Device Instance Path) of a composite device (i.e. a device having child devices) and number of iterations (N) as command line parameter. It finds the device and all its children and stores them in a list. It then disables and re-enables the device. After this operation, it again finds the children of the device and stores them in another list. The previous list is compared with that of the current list of devices. If both the lists are same, then the test is repeated until all of the N iterations are complete. During this process, if the base list and current list is not matched, then the test is marked as failed and is ended.
