+简介
+----
+
+ESP-IDF USB 主机协议栈允许 {IDF_TARGET_NAME} 作为 USB 主机运行，此时，{IDF_TARGET_NAME} 能够与各种 USB 设备通信。然而，大多数 USB 主机协议栈实现都不运行在嵌入式硬件上（即在电脑和手机端运行），因此，相对来说具有更多的资源（即，具有更高内存和 CPU 速度）。
+
+ESP-IDF USB 主机协议栈（以下简称为主机协议栈）的实现考虑到了 {IDF_TARGET_NAME} 的嵌入式特性，这体现在主机协议栈设计的各个方面。
+
+特性和局限性
+^^^^^^^^^^^^
+
+**主机协议栈目前支持以下显著特性：**
+
+- 支持 FS（全速）和 LS（低速）设备
+- 支持所有传输类型（控制传输、批量传输、同步传输和中断传输）
+- 自动枚举已连接设备
+- 允许多个类驱动程序（即 USB 主机库的客户端）同时运行并共享同一设备（即组合设备）
+
+**主机协议栈目前存在以下显著局限：**
+
+- 不支持 HS（高速）设备
+- 不支持集线器（当前仅支持单个设备）
