Abstract:
A USB host control method is provided for a USB host controller. The USB host controller includes a USB device and a buffer, the USB device includes one or more endpoints. The USB host control method includes the steps of: storing first output data to be sent to a first endpoint into one or more buffer units used for the first endpoint; sending the first output data to the first endpoint; and when a first predetermined response from the first endpoint is received, configuring fake releasing labels and information tags corresponding to the first endpoint in the one or more buffer units, and not releasing the one or more buffer units.
