Abstract
In some embodiments, an electronic system includes a processor, a memory in communication with the processor, a bus in communication with the processor, an Express Card controller coupled to the bus, the Express Card controller providing an interface to an external device, a USB3 controller coupled to the bus and in communication with the Express Card controller, and a PCIE controller coupled to the bus and in communication with the Express Card controller. The Express Card controller may be configured to determine whether the external device is a USB3 device or a PCIE device and to switch between the USB3 controller and the PCIE controller based on the state of a USB3 select pin strap. Other embodiments are disclosed and claimed.
