@ -33,7 +33,7 @@ The Host Library has the following features:
:esp32p4: - Supports High Speed (HS), Full Speed (FS) and Low Speed (LS) Devices.
- Supports all four transfer types: Control, Bulk, Interrupt, and Isochronous.
:esp32p4: - Supports High-Bandwidth Isochronous endpoints.
:esp32p4: - {IDF_TARGET_NAME} includes two USB 2.0 OTG peripherals: one High-Speed and one Full-Speed. Both support USB Host functionality; however, due to a current software limitation, only one can operate as a USB Host at a time. Support for dual USB Host operation is planned for a future update.

- Allows multiple class drivers to run simultaneously, i.e., multiple clients of the Host Library.
- A single device can be used by multiple clients simultaneously, e.g., composite devices.
- The Host Library itself and the underlying Host Stack does not internally instantiate any OS tasks. The number of tasks is entirely controlled by how the Host Library interface is used. However, a general rule of thumb regarding the number of tasks is ``(the number of host class drivers running + 1)``.

@ -33,6 +33,7 @@ USB 主机库（以下简称主机库）是 USB 主机栈的最底层，提供
:esp32p4: - 支持高速 (HS)、全速 (FS) 和低速 (LS) 设备。
- 支持四种传输类型，即控制传输、块传输、中断传输和同步传输。
:esp32p4: - 支持高带宽等时性端点。
:esp32p4: - {IDF_TARGET_NAME} 包含两个 USB 2.0 OTG 外设：USB 2.0 OTG 高速和 USB 2.0 OTG 全速，二者均支持 USB 主机功能。但由于当前软件的限制，同一时间仅能有一个作为 USB 主机工作。未来版本计划支持两个 USB 主机同时运行。
- 支持多个 Class 驱动程序同时运行，即主机的多个客户端同时运行。
- 单个设备可以由多个客户端同时使用，如复合设备。
- 主机库及其底层主机栈不会在内部自动创建操作系统任务，任务数量完全由主机库接口的使用方式决定。一般来说，任务数量为 ``（运行中的主机 Class 驱动程序数量 + 1）``。

- 仅支持异步传输。
- 仅支持使用发现的首个配置，尚不支持变更为其他配置。
- 尚不支持传输超时。
:esp32p4: - {IDF_TARGET_NAME} 包含两个 USB-OTG 外设：USB 2.0 OTG 高速和 USB 2.0 OTG 全速。目前仅支持高速实例。
- 外部 Hub 驱动：不支持远程唤醒功能（即使没有设备插入，外部 Hub 也处于工作状态）。
- 外部 Hub 驱动：不处理错误用例（尚未实现过流处理、初始化错误等功能）。
- 外部 Hub 驱动：不支持接口选择。驱动程序使用具有 Hub 类代码 (09h) 的第一个可用接口。
