USB Subtests Added

The following subtests have been added to the System Set Test Group. These subtests run only if the computer has a Universal Serial Bus (USB) connector.

The USB Register Test checks the onboard registers of the USB interface. This subtest does not test USB peripherals.

The USB Memory Structure Test monitors the abil- ity of a USB controller to process a simple set of memory-resident instructions.
