Abstract: Methods and apparatus for reliable detection and enumeration of devices. In one embodiment, the controller comprises serialized bus protocol (e.g., a Universal Serial Bus (USB)) controller capable of supporting different bus architectures (e.g., USB 2.0 and USB 3.0) of the USB protocol (e.g., eXtensible Host Controller Interface (xHCI) controller). In one variant, when a USB-compliant device is detected over multiple bus architectures of a controller, the controller waits an additional period to allow the device to properly identify which bus architecture to use. After the time period has elapsed, if the device has been determined to be connected over the USB 3.0 bus architecture, the controller waits an additional period of time before enumerating the device. If the device is still present on the USB 3.0 bus architecture, the device continues to enumerate as a USB 3.0 advice to be made available to a host system.

Abstract: Methods and apparatus for dynamically allocating resources to a plurality of controllers are disclosed. In one embodiment, the controllers comprise multiple types of Universal Serial Bus compliant controllers. When a USB-compliant device is detected, one or more determinations are made regarding the detected device such as the supported data transfer speed capabilities. Based on the one or more determinations, the device is directed to an appropriate controller.
