Description of problem: The platform on which we run redhat-ready certification v.2-0.9-14.2 has no PS/2 keyboard&mouse, we use usb keyboard and mouse. The test fails to recognize that a USB device has been removed from the server after one is unplugged during the interactive portion of the test with this error: "(USB:x) no USB devices removed!" <x = port number tested>. The certification test is not designed for systems which has USB keyboard and mouse and as a result, the test prompts user to remove these devices before starting the test. Clearly, without any usb keyboard the test can not be completed. Test passes if the redhat-ready is executed over the serial console while both keyboard and mouse are unplugged.
legacyfree is a hardware.conf option specifically for the above. It should allow you to leave the keyboard plugged in during the testing and simply add/subtract things from the other ports which should be empty before starting the test.
I'm going to go ahead and close this one assuming "legacyfree" resolved the above. Otherwise see bug #141575 for a related USB problem.
