摘要

USB构成了与外部世界通信的主干。当USB设备连接到USB主机时，为建立通信通道而发生一系列交互，称为枚举。本文详细阐述了USB2.0的枚举过程，并讨论了与枚举相关的几个问题在硅后调试过程中所面临的挑战。作为案例研究，我们将分析在枚举过程中发现的两个问题。第一个问题与进程挂起的重复枚举有关，第二个问题与超时失败有关。

Post Silicon Debugging Approach for USB2.0: Case Study of Enumeration

USB forms the backbone of communication to external world. When a USB device is attached to a USB host, a sequence of interaction happens for establishing the communication channel, known as enumeration. This paper explains the enumeration process of USB2.0 in detail and discusses the challenges faced during post silicon debug of couple of issues related with enumeration. As a case study we will analyze two issues which were found during enumeration. The first issue is related to repeated enumeration in which process hangs and second is related to timeout failure.
