To certify a stand alone USB hard disk, solid-state storage device, or multimedia card reader, that is not built-in with the system, you need to perform the plug or unplug test before starting the automated USB storage certification.
Before You Begin
Before starting the automated USB storage certification, unplug the storage device to be certified from the SUT then plug it back. Repeat this test 10 times.
After this step, Oracle HCTS can detect the USB storage device to be certified.
