  • Universal serial bus transaction processing tasks scheduling method for computer system, involves assigning transaction to periodic queue head list with faster polling interval
    Patent number: 6938103
    Abstract: An apparatus and method is provided for scheduling USB transaction processing tasks. A periodic queue head list associated with a USB host controller is configured to be processed once every polling period. The periodic queue head list describes a location of the USB transaction processing tasks scheduled for processing. The entries in a frame list of the USB host controller are linked to identify a corresponding periodic queue head list. A USB transaction processing task processed by the USB host controller is assigned to one of the periodic queue head list. A desired response time for the USB transaction processing task is matched with the polling period of the periodic queue head list.
