Abstract
A data storage device and method for lane detection and configuration are provided. In one embodiment, a data storage device is provided comprising a memory, an interface, and a controller. The controller is configured to detect whether a cable coupled with the interface 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 not providing either the first or the second channel configuration signal, the controller uses a default lane configuration to communicate with the host via the cable. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.
