Fifth tier operation - OHCI


This test is designed to show operation under moderate signal and timing stress.

Install the CleanOSBuild image using something like the following command: dd if=CleanOSBuild of=/dev/hda5 bs=8192.

Construct a hub tree as follows:

Perform all typical end-user scenarios at the ports behind the tier five hub downstream in the system.

If the Hub Under Test operates correctly when attached to the root hub, but does not work correctly when attached to the tier four hub, the most likely cause is excessive current draw.

If any problems occur during this scenario, they need to be resolved prior to continuing to subsequent tests.
