摘要
In one embodiment, a Universal Serial Bus (USB) system assigns a first priority level to a first USB endpoint and a second priority level that is lower than the first priority level to a second USB endpoint. The USB system has memory that stores first USB data packets corresponding to the first priority level and second USB data packets corresponding to the second priority level. The USB system also has a controller that manages transfers of (i) the first USB data packets to the first USB endpoint and (ii) the second USB data packets to the second USB endpoint. If the memory concurrently stores first and second USB data packets, then the controller determines an order for transferring the first and second USB data packets based on the second priority level being lower than the first priority level and/or detection of a starvation condition for the second endpoint.
