5. Useful LED combinations
The LEDs for the corresponding pins need to light up to make sure the desired mode is available. Please note that
shorted pins, diodes, active electronics or other faults/things inside the cable can provide false results. Options A
and B are for the two possible connector I orientations and can be inverted by flipping the cable at connector I .
If D+ and D- are connected, they only light up on one side of the tester. This is for compatibility with older USB
connector generations and can be inverted by flipping connector I.
