Troubleshooting Device.Connectivity Testing

To troubleshoot issues with PCI device, USB devices, or USB hub connectivity tests, follow these steps:

  1. Review:

  2. Verify that you have installed the latest Windows HCK filters and kit updates. For more information, see Windows Hardware Certification Kit Filters.

  3. For a test failure, look for usable information in the Windows HCK Studio test log. If you find usable information, resolve the issue and rerun the test.

  4. If you cannot obtain a successful test result, contact Windows HCK Support.

The advantages of connecting a device to a USB 2.0 hub are as follows:

  • We recommended this connection for regular USB devices.

  • This connection is required for the USB Selective Suspend test. For more information, see USB Selective Suspend.

  • This connection forces the Enhanced Host Controller Interface (EHCI) high-speed controller to enumerate low-speed and full-speed devices.

The disadvantages of connecting a device to a USB 2.0 hub are as follows:

  • Devices that have embedded hubs must be directly connected for certification tests.

  • We do not recommend multi-TT (transaction translator) hubs for certification testing.

When you are testing a device that has an embedded high-speed hub, attach the device directly to the system for all tests.
