应当理解， 此处所描述的具体实施例仅仅用以解释本发明， 并不用于 限定本发明。
如图 1所示， 图 1为本发明一实施例中 USB设备自动识别操作系统的 方法的流程图， 该实施例提到的 USB设备自动识别操作系统的方法包括： 步驟 S10,判断是否接收到主机发送的操作系统字符串描述符请求； 如 果是， 则执行步驟 S21 ; 如果否， 则执行步驟 S30;
步驟 S21 , 判定主机的操作系统为 WINDOWS操作系统；
步驟 S30, 判断是否接收到主机发送的操作系统特性描述符请求； 如果 是， 则执行步驟 S21 ; 如果否， 则执行步驟 S22;
步驟 S22, 判定主机的操作系统为 LINUX核操作系统。
本实施例中， 由于 MOSD ( Microsoft OS Descriptors, 微软操作系统描 述符， 其中 OS ( Operating System, 操作系统））是微软产品中特有的描述 符， 包括 OS String Descriptor (操作系统字符串描述符） 和 OS Feature Descriptor (操作系统特性描述符）， 只有 WINDOWS操作系统的主机才会 向接入的 USB设备发送 MOSD。 其中， 主机为个人电脑 PC, 或其他支持 USB 主控制器的设备， 例如掌上电脑等， WINDOWS 操作系统包括 WINDOWS SP2及以上系统，例如 WINDOWS XP SP2、 win7、 windows vista 等。 本实施例将 OS String Descriptor和 OS Feature Descriptor请求作为 WINDOWS操作系统的识别指令， 当 USB设备接收到 OS String Descriptor 或 OS Feature Descriptor请求时， 则判定该 USB设备接入的是 WINDOWS 操作系统的主机。 如果主机的操作系统为 LINUX核操作系统， 则主机不会 向 USB设备发送 OS String Descriptor或 OS Feature Descriptor请求。本实施 例以 WINDOWS操作系统自带的 MOSD作为技术支撑，无需添加其他过滤 驱动或光盘功能即可实现操作系统的自动识别， 有效降低了开发成本， 且 操作简单方便， 有效提高 USB设备用户体验。 如图 2所示， 图 2为本发明另一实施例中 USB设备自动识别操作系统 的方法的流程图， 该实施例包括响应请求的步驟。
步驟 S40, 当 USB设备接收到主机发送的操作系统字符串描述符请求 时， 向主机回复操作系统字符串描述符请求的响应； 步驟 S50,主机根据操作系统字符串描述符请求的响应发送操作系统特 性描述符请求至 USB设备。
本实施例中针对 WINDOWS操作系统的主机，当 USB设备首次接入主 机时， WINDOWS操作系统主机将向 USB设备发送 OS String Descriptor请 求， USB设备对接收到的 OS String Descriptor请求做出响应， 并将响应发 给主机识别，主机通过辨别 USB设备是否对主机下发的 OS String Descriptor 请求做出响应，来判断 USB设备中的功能特性是否支持 WINDOWS操作系 统， 只有对于支持 WINDOWS操作系统的 USB设备， WINDOWS操作系 统才会发送后续 OS Feature Descriptor请求指令， 以实现相关功能。 如果主 机的操作系统为 LINUX核操作系统，则主机不会向 USB设备发送 OS String Descriptor请求。
步驟 S60,当 USB设备接收到主机发送的操作系统特性描述符请求时， 向主机回复操作系统特性描述符请求的响应。
步驟 S70, 主机获取 USB设备的功能特性， 完成对应操作。
本实施例中， 当 WINDOWS操作系统的主机接收到 USB设备回复的 OS Feature Descriptor请求的响应， 则可从 USB设备中获取 USB设备包含 的具体功能特性， 并可完成各功能特性对应的相关操作。 如果 USB设备判 定主机的操作系统为 LINUX核操作系统， 则 LINUX核操作系统可直接与 USB设备进行各特殊功能相关操作。 如图 3所示， 图 3为本发明另一实施例中 USB设备自动识别操作系统 的方法的流程图， 该实施例中包括处理操作系统字符串描述符请求的响应 的步驟。 步驟 S40具体包括：
步驟 S41， 主机在注册表中记录 USB设备已发送操作系统字符串描述 符请求的响应；
步驟 S42, 在 USB设备下一次与主机连接时， 判断注册表中是否存在 该 USB设备对操作系统字符串描述符请求的响应；如果是，则执行步驟 S43； 如果否， 则执行步驟 S44;
步驟 S43， 主机发送操作系统特性描述符请求至 USB设备；
步驟 S44, 主机终止向 USB设备下发操作系统特性描述符请求。
本实施例中， OS String Descriptor请求主要用来判断 USB设备中的功 能特性是否支持 WINDOWS操作系统， 当 USB设备首次接入 WINDOWS 操作系统主机， 并向主机回复了 OS String Descriptor请求的响应后， 主机 将在注册表中记录下来， 并且判定该 USB设备支持 WINDOWS操作系统； 当该 USB设备以后再一次接入同一个主机时， 在这个主机的注册表中就会 找到该 USB设备已对 OS String Descriptor请求回复了响应的记录， 则主机 直接向该 USB设备下发 OS Feature Descriptor请求， 无需重新向该 USB设 备发送 OS String Descriptor请求， 也无需判断该 USB设备的功能特性是否 支持 WINDOWS操作系统。如果注册表中记录 USB设备的功能特性不支持 WINDOWS操作系统， 则当该 USB设备以后接入同一个主机时， 主机均不 会向该 USB设备下发后续 OS Feature Descriptor请求指令。 本实施例在 WINDOWS操作系统主机利用注册表进行记录，只对首次接入的 USB设备 发送 OS String Descriptor请求并接收 USB设备回复的响应，在同一 USB设 备再次接入时， 只需查找注册表中的记录， 即可判断是否下发 OS Feature Descriptor请求， 为后续主机获取 USB设备的功能特性并完成对应操作节 省了时间， 处理速度更快， 工作效率得到有效提高。 如图 4所示， 图 4为本发明一实施例中 USB设备自动识别操作系统的 系统的结构示意图， 该实施例提供的 USB设备自动识别操作系统的系统包 括：
主机 400 ,用于发送操作系统字符串描述符请求或操作系统特性描述符 请求； USB设备 500 , 该 USB设备 500具体包括：
请求接收模块 10 , 用于判断是否接收到主机 400发送的操作系统字符 串描述符请求或操作系统特性描述符请求；
操作系统识别模块 20, 用于当接收到主机 400发送的操作系统字符串 描述符请求或操作系统特性描述符请求时， 判定主机 400 的操作系统为 WINDOWS操作系统； 当未接收到主机发送的操作系统特性描述符请求时， 判定主机的操作系统为 LINUX核操作系统。
本实施例中， 主机 400为个人电脑 PC, 或其他支持 USB主控制器的 设备，例如掌上电脑等。如果主机 400的操作系统为 WINDOWS操作系统， 包括 WINDOWS SP2及以上系统，例如 WINDOWS XP SP2、 win7、 windows vista等， 则主机 400会向 USB设备 500发送微软产品特有的 MOSD, 包括 OS String Descriptor 和 OS Feature Descriptor 本实施例将 OS String Descriptor和 OS Feature Descriptor请求作为 WINDOWS操作系统的识别指 令，当设置于 USB设备 500中的请求接收模块 10接收到 OS String Descriptor 或 OS Feature Descriptor请求时， 则由设置于 USB设备 500中的操作系统 识别模块 20判定该 USB设备 500接入的是 WINDOWS操作系统的主机 400。如果主机 400的操作系统为 LINUX核操作系统，主机 400不会向 USB 设备发送 OS String Descriptor或 OS Feature Descriptor请求， 操作系统识别 模块 20则判定该 USB设备 500接入的是 LINUX核操作系统的主机 400。 本实施例以 WINDOWS操作系统自带的 MOSD作为技术支撑，无需添加其 他过滤驱动或光盘功能即可实现操作系统的自动识别， 有效降低了开发成 本， 且操作简单方便， 有效提高 USB设备用户体验。 如图 5所示， 图 5为本发明另一实施例中 USB设备自动识别操作系统 的系统的结构示意图， 该实施例中 USB设备 500还包括请求响应模块 30, 用于当接收到主机发送的操作系统字符串描述符请求时， 向主机回复操作 系统字符串描述符请求的响应；
主机 400具体用于根据操作系统字符串描述符请求的响应发送操作系 统特性描述符请求至 USB设备 500。
本实施例在 USB设备 500首次接入主机 400时， 如果主机 400的操作 系统为 WINDOWS操作系统，则需要判断 USB设备 500中包含的功能特性 是否支持 WINDOWS操作系统， 即该一个或多个特性描述是否有专用于 WINDOWS操作系统的功能。本实施例是通过辨别设置于 USB设备 500中 的请求响应模块 30是否对主机 400下发的 OS String Descriptor请求做出响 应，来判断 USB设备 500中的功能特性是否支持 WINDOWS操作系统，只 有对于支持 WINDOWS操作系统的 USB设备 500 , WINDOWS操作系统才 会发送 OS Feature Descriptor请求到 USB设备 500, 以实现相关功能。 如果 主机 400的操作系统为 LINUX核操作系统， 则主机 400不会向 USB设备 500发送 OS String Descriptor请求。 本发明实施例中， 请求响应模块 30还用于：
当接收到主机 400发送的操作系统特性描述符请求时， 向主机 400回 复操作系统特性描述符请求的响应。
本实施例中， 当请求接收模块 10接收到主机 400发送的 OS Feature Descriptor请求后， USB设备 500中设置的请求响应模块 30还对 OS Feature Descriptor请求做出响应， 提示主机 400可以提取功能特性。 如果主机 400 的操作系统为 LINUX核操作系统， 则主机 400不用等待请求响应模块 30 回复 OS Feature Descriptor响应， 即可直接根据 USB设备 500包含的针对 LINUX核操作系统的功能特性进行相关操作。 本发明实施例中， 主机 400进一步用于：
当接收到操作系统字符串描述符请求的响应时， 在注册表中记录 USB 设备 500已发送操作系统字符串描述符请求的响应；
在 USB设备 500下一次与主机 400连接时， 判断注册表中是否存在该 USB设备 500对操作系统字符串描述符请求的响应；
如果是， 则发送操作系统特性描述符请求至 USB设备 500;
如果否， 则终止向 USB设备 500下发操作系统特性描述符请求。
本实施例中，当 USB设备 500包含的功能特性支持 WINDOWS操作系 统时， USB设备 500中设置的请求响应模块 30才会对 OS String Descriptor 请求做出正确的响应。 对于第一次接入 WINDOWS操作系统主机 400 的 USB设备 500, 当 USB设备 500向主机回复 OS String Descriptor请求的响 应后， 主机 400则会在注册表中将该 USB设备 500的响应记录下来； 当该 USB设备 500以后再一次接入同一个主机 400时， 在这个主机 400的注册 表中就会找到该 USB设备 500已回复对 OS String Descriptor请求的响应的 记录， 则主机 400直接向该 USB设备 500下发 OS Feature Descriptor请求 至 USB设备 500, 无需重新发送 OS String Descriptor请求判断该 USB设备 500的功能特性是否支持 WINDOWS操作系统。 否则， 当该 USB设备 500 以后接入同一个主机 400时， 主机 400均不会向该 USB设备 500下发 OS Feature Descriptor请求识别指令。上述实施例只对首次接入主机 400的 USB 设备 500进行判断， 辨别其功能特性是否支持 WINDOWS操作系统， 并记 录判断结果， 可以为该 USB设备 500再次接入同一主机 400时提供参考依 据， 主机 400会根据记录选择是否发送 OS Feature Descriptor请求， 减少操 作系统识别过程的处理流程， 提高处理效率。 本发明实施例中， 主机 400还用于当接收到操作系统特性描述符请求 的响应时， 获取 USB设备 500的功能特性， 完成对应操作。
本实施例中， 当 WINDOWS操作系统的主机 400接收到 USB设备 500 回复的 OS Feature Descriptor响应， 则主机 400可从 USB设备 500中获取 具体功能特性， 并根据功能特性完成对应的相关操作。 如果 USB设备 500 判定主机 400的操作系统为 LINUX核操作系统， 则 LINUX核操作系统可 直接与 USB设备 500进行各特殊功能相关操作。 以上所述仅为本发明的优选实施例， 并非因此限制本发明的专利范围， 凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换， 或直 接或间接运用在其他相关的技术领域， 均同理包括在本发明的专利保护范 围内。 工业实用性
本发明以 WINDOWS操作系统自带的 MOSD作为技术支撑，无需添加 其他过滤驱动或光盘功能即可实现操作系统的自动识别， 有效降低了开发 成本， 且操作简单方便， 有效提高 USB设备用户体验。
