图 1是本发明第一实施例的 USB设备自动识别微软窗口化操作系统版 本的方法的流程示意图；
图 2是本发明第二实施例的 USB设备自动识别微软窗口化操作系统版 本的方法的流程示意图；
图 3是本发明第一实施例的 USB设备的结构框图。 具体实施方式
目前主流的操作系统为 Windows操作系统， Windows操作系统包括 Windows XP、 VISTA、 Windows7 ( WIN7 ) 以及 Windows8 ( WIN8 ), 各种 操作系统在对 USB 设备的支持上都有自己的特性， 并且在高版本的 Windows操作系统上一般会增加新的 USB设备类型。 USB协议中规定： USB设备可以同时存在多套配置，但在某一时刻只是其中某一套配置生效。 当 USB设备插入主机后，主机会下发 USB请求来获取设备描述符、配置描 述符和接口描述符等信息， 如果 USB设备中存在多套配置， 需要在设备描 述符中填充具体的配置数目， 主机可以根据 USB上报的配置数目， 下发请 求来获取所有具体的配置参数。
Windows操作系统在 Windows XP、 Vista、 Windows7 ( WIN7 ) 以及 Windows8 ( WIN8 )上， 支持了一条特殊的扩展指令为 Windows操作系统 的 MOSD，保证安装有 Windows操作系统的主机允许 USB设备通过 MOSD 上报某些上报特定的信息。 其中在 WIN8 上有一条特殊的 MOSD 为 "ALTRCFG" , 可以让 WIN8选择某一套特定的配置。
另夕卜， 当 USB设备枚举为 TF卡时， 主机和 USB设备之间会通过小型 计算机系统接口 （ Small Computer System Interface， SCSI )指令进行交互。 在 SCSI指令中， 有一条查询（ INQUIRY )指令， 是用来返回当前逻辑单元 ( Logic Unit, LU ) 的特定信息的。 所述主机可以为计算机， 所述的 USB设备可以为无线网卡、 无线数据 卡等。
本发明基于上述的 SCSI指令中的 INQUIRY指令以及 Win8的 MOSD 的特点， 提供了一种 USB设备自动识别微软窗口化操作系统版本的方法和 USB设备。
图 1是本发明第一实施例的 USB设备自动识别微软窗口化操作系统版 本的方法的流程示意图， 如图 1所示， 本发明第一实施例所述的 USB设备 自动识别微软窗口化操作系统版本的方法， 包括以下步骤：
步骤 11 : USB设备接入主机， 向所述主机上报 M个配置参数， M为 大于 1的整数；
步骤 12: 所述 USB设备枚举为 TF卡设备，在枚举过程中所述 USB设 备向所述主机上报支持配置参数指定功能的微软窗口化操作系统描述符 MOSD, 所述配置参数指定功能指定配置值设为第 N个配置参数， N为大 于 1而小于等于 M的整数；
步骤 13: 当所述 USB设备检测到所述主机从该 USB设备获取与该第 N个配置参数对应的配置描述符时， 则判定当前微软窗口化操作系统的版 本为 Win8;
步骤 14: 当所述 USB设备检测到所述主机从该 USB设备获取与第一 个配置参数对应的配置描述符时， 如果所述 USB设备只接收到一条所述主 机下发的查询指令， 则判定当前微软窗口化操作系统的版本为 XP， 如果所 述 USB设备接收到所述主机下发的至少两条查询指令则判定当前微软窗口 化操作系统的版本为 Vista或 Win7。
本发明第一实施例所述的 USB设备自动识别微软窗口化操作系统版本 的方法， 可以在完全不需要在主机上安装任何程序进行辅助的情况下， 使 得 USB设备可以自动区分目前 Windows操作系统的具体版本类型， 使得 USB设备在针对不同类型的 Windows操作系统的使用上更加灵活， 实施过 程简便， 可操作性强， 有效解决了现有技术中需在主机上安装不同软件来 检测 Windows操作系统类型的方法带来的兼容性问题。
举例来说， 本发明所述的 USB设备自动识别微软窗口化操作系统版本 的方法在具体实施时：
首先， USB设备接入到主机上， 向所述主机上报五个配置参数； 然后所述 USB设备将自身枚举为 TF卡设备， 在枚举的过程中会向所 述主机上报 MOSD 信息， 具体向所述主机上报支持 ALTRCFG 功能， ALTRCFG中指定配置值设为第二个配置参数；
当所述 USB设备检测到所述主机从该 USB设备获取与该第二个配置参 数对应的配置描述符时， 则判定所述主机上安装的 Windows操作系统的版 本为 Win8， 而当所述 USB设备检测到所述主机依旧默认从该 USB设备获 取与第一个配置参数对应的配置描述符时， 判定所述主机上安装的 Windows操作系统的版本非 Win8;
当所述 USB设备判定所述主机上安装的 Windows操作系统的版本非 Win8时， 如果所述 USB设备检测到所述主机仅向该 USB设备下发了一条 INQUIRY指令，则判定所述主机上安装的 Windows操作系统的版本为 XP， 如果所述 USB 设备检测到所述主机向该 USB 设备下发了至少两条 INQUIRY指令，则判定所述主机上安装的 Windows操作系统的版本为 Vista 或者 Win7。
现有的 Windows操作系统自身能够支持的 USB网络设备驱动即 RNDIS 网络驱动和 MBIM网络驱动。 其中， RNDIS驱动协议在目前主流的 XP、 Vista, Win7和 Win8上均支持。 但是 XP上需要提供驱动安装文件来引导 系统安装 RNDIS驱动， Vista、 Win7和 Win8可以自身加载 RNDIS驱动， 需要引导。 但是只有 Win8支持 MBIM驱动， MBIM时微软在 Win8上提出 的一种全新的移动宽带接口模型。
基于以上的特性， 本发明实施例所述的 USB设备自动识别微软窗口化 操作系统版本的方法，在识别了主机上安装的 Windows操作系统的版本后， 还可以根据具体的版本完成 USB网络设备驱动。
优选地， 本发明实施例所述的 USB设备自动识别微软窗口化操作系统 版本的方法， 还包括： 当所述 USB设备判定微软窗口化操作系统的版本为 XP时， 将 USB端口枚举为虚拟光盘， 或枚举为虚拟光盘和 TF卡设备的组 合， 利用所述虚拟光盘中的驱动安装文件引导远程网络驱动接口规范 RNDIS驱动。
优选地， 本发明实施例所述的 USB设备自动识别微软窗口化操作系统 版本的方法， 还包括： 当所述 USB设备判定微软窗口化操作系统的版本为 Win8时，向所述主机发送 MBIM驱动加载信号，使所述主机自动加载 MBIM 驱动。

步骤 201 : USB设备接入主机， 向所述主机上报 M个配置参数， M为 大于 1的整数； 步骤 202: 所述 USB设备枚举为 TF卡设备， 在枚举过程中所述 USB 设备向所述主机上报支持配置参数指定功能的 MOSD， 所述配置参数指定 功能指定配置值设为第 N个配置参数， N为大于 1而小于等于 M的整数； 步骤 203: 所述 USB设备判断所述主机是否从该 USB设备获取与该第 N 个配置参数对应的配置描述符， 如果是则执行步骤 204， 否则执行步骤 205;
步骤 204:所述 USB设备判定当前微软窗口化操作系统的版本为 Win8， 转至步骤 209;
步骤 205: 所述 USB设备判断其是否只接收到一条所述主机下发的查 询指令， 如果是则执行步骤 206， 否则执行步骤 207;
步骤 206: 所述 USB设备判定当前微软窗口化操作系统的版本为 XP， 转至步骤 208;
