Claim 0:
1. A data storage device comprising:
a memory;
an interface configured to couple with a cable; and
a controller configured to communicate with the memory and the interface and further configured to:
detect whether the cable is providing a first channel configuration signal that indicates that the cable is in a first cable orientation or a second channel configuration signal that indicates that the cable is in a second cable orientation;
in response to detecting that the cable is providing the first channel configuration signal, use a first lane configuration to communicate with a host via the cable;
in response to detecting that the cable is providing the second channel configuration signal, use a second lane configuration to communicate with the host via the cable; and
in response to detecting that the cable is providing neither the first nor the second channel configuration signal either due to a lack of an orientation-handling circuit in the cable or due to the cable comprising the orientation-handling circuit but the first or the second channel configuration signal being undetectable due to noise or invalid information, use a default lane configuration to communicate with the host via the cable.
