Detailed Description

USB 设备类接口基类，所有自定义 USB 类（如 HID、CDC、MSC）都需派生自本类。 USB device class base interface, all custom device classes (HID, CDC, MSC, etc.) should derive from this.

Note: 仅供 DeviceCore 内部驱动和派生类扩展，普通用户无需直接使用。 Only for internal drivers and derived classes, users do not need to use it directly.
