Abstract
A USB host controller is provided. The USB host controller is capable of communicating with multiple USB apparatuses having endpoints and sends a request to a first endpoint. The USB host controller includes a first storage and a first control unit. The first control unit stores endpoint information from the first endpoint into the first storage when the first endpoint issues an unready transaction packet in response to the request. The unready transaction packet indicates that the first endpoint is not ready.
