Abstract
A diagnosis mechanism for host controllers such as USB (Universal Serial Bus) host controllers is provided. The host controller has a register set that comprises at least one host controller capability register storing data indicative of operational capabilities of the host controller, and at least one host controller operational register storing data for controlling the operation of the host controller. The at least one host controller capability register stores data that is indicative of available diagnostic modes that the host controller can enter. The at least one host controller operational register stores diagnosis data for controlling the operation of the USB host controller in diagnostic modes. This diagnosis mechanism may improve the reliability of the host controller operation.
