Multiple identical devices - OHCI
 | The end user may have a requirement to have more than one identical device attached to the system. Verify that the device application and device driver operate with multiple identical devices attached to the system. |
Using the same hub tree as the Fifth Tier Operation - OHCI test, add the second Device Under Test using a five metre cable to a spare port on the tier five hub. If applicable, add the "similar device" to a spare port on the tier five hub.
Ensure all three devices are fully functional:
Hot attach - no installation is required.
Application installation - if required to show functionality
Warm boot - system remains functional
Cold boot - system remains functional
Asynchronous detach and reattach
USB topology change - no driver modification required
Suspend / Resume - functional after resume
Suspend / Remote-wake (if applicable) - functional after wake-up
