摘要
鉴于人工热插拔实验效率低下,难以评估USB设备的热插拔特性,设计了一种USB设备自动热插拔检测系统,用于评估不同应用场景下的USB热插拔特性。给出了该系统的硬件结构和软件流程。在实验室进行了验证,结果表明:该系统能够高效地考核USB接口设备的热插拔性能。
Considering inefficiency of manual hot-plugging experiments and the difficulty in evaluating the hot-plugging characteristics of USB devices, a USB automatic hot-plugging system was designed to evaluate the USB hot-plugging characteristics in different application scenarios, and both hardware structure and software process were presented. Verification in lab shows that, this system can efficiently evaluate the hot-plugging performance of USB interface devices.
