Description

USB设备的驱动方法、主机及USB设备 技术领域
本发明涉及计算机技术领域，尤其涉及USB设备的驱动方法、主机及USB设备。
背景技术
通常当通用串行总线(Universal Serial Bus，简称为USB)设备接入主机后，主机对USB设备进行驱动以使USB设备与主机建立数据传输通道。
下面以数据卡为例说明主机驱动USB设备的方式，对于手机、平板电脑等其他USB设备，主机对其的驱动方式与数据卡相似：
方式一，主机发送获取设备描述符等请求，USB设备收到请求后，上报相关功能端口，主机根据设备上报的功能端口加载相应驱动。在这种情况下，USB设备一般上报为大容量存储(MASS STORAGE)设备，这样用户就可以在主机上安装存在于MASS STORAGE设备中的用户界面(User Interface，简称为UI)和驱动(DRIVER)等软件。当用户安装完毕后，为了能够使用USB设备进行联网或其它操作，UI或者DRIVER会主动发送指令给USB设备，进行模式切换，将USB设备从MASS STORAGE切换到可以联网的模式，例如NDIS。
方式二，主机发送获取设备描述符等请求，USB设备根据这些请求进行主机操作系统的判断，例如是Windows还是Linux，然后USB设备根据判断结果上报不同的功能端口，一般这些功能端口用于联网操作，并且这些功能端口的驱动属于操作系统自带的，已经存在于操作系统中，主机根据设备上报的功能端口加载相应驱动。
上述两种驱动USB设备的方式在将USB设备的功能端口固定后，USB设备的功能也随之固定了，任何人在任何主机上均可以操作所有的功能端口，存在许多安全隐患。

具体实施方式
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。
本领域技术人员可以理解的，本发明实施例USB设备的驱动方法、主机及USB设备的下述实施例中，所述主机可应用于计算机、电视机等终端中，所述USB设备是指以USB方式与主机连接的设备，包括：手机、平板电脑、照相机、U盘等，本发明并不对此进行限定。
本发明实施例提供一种USB设备的驱动方法。
参照图1，图1为本发明USB设备的驱动方法第一实施例的流程示意图。
本发明USB设备的驱动方法第一实施例中，该USB设备的驱动方法包括：
步骤S10，在主机与USB设备建立连接后，主机获取USB设备根据用户权限设置的功能配置信息；
主机在与USB设备建立连接后，可由主机获取用户的用户权限，也可由USB设备获取用户的权限，获取用户权限的方法可以是通过密码验证、人脸识别、手势验证、声音验证、指纹验证等方式进行。其中，用户权限可预先设置，根据用户的需求，可设置为Administrator(管理员)、Guest(访客)，也可设置为多个用户权限等级，本发明对此不作限定。
功能配置信息是USB设备根据用户权限设置的，功能配置信息包括用户权限可使用的功能端口的配置。
步骤S20，主机根据获取的功能配置信息，生成与所述功能配置信息对应的功能端口。
由于功能配置信息是由USB设备根据用户权限设置的，因此，主机根据该功能配置信息对应生成的功能端口即为用户权限对应的功能端口。
主机根据功能配置信息生成与该功能配置信息对应的功能端口的方法与现有技术相似，在此不作赘述。
本实施例USB设备根据用户权限设置相应的功能配置信息，主机根据USB设备设置的功能配置信息生成功能端口，因此，本实施例中，对于不同的用户权限，该用户可使用的功能端口是不同的，即用户可使用的功能也是不同的，因此，能提升USB设备的安全性，且功能端口的配置更灵活；此外，根据一些用户权限仅对应生成部分功能端口，USB设备不需要同时在主机上开启其所有的功能端口，因此，可提升USB设备的性能、降低功耗。
参照图2，图2为本发明USB设备的驱动方法第二实施例的流程示意图。
本发明USB设备的驱动方法第二实施例中，本实施例在第一实施例的基础上，所述步骤S10包括：
步骤S11，主机发送获取指令至USB设备；
在主机与USB设备建立连接后，或者，在主机与USB设备重新建立连接后，主机发送获取指令至USB设备。
步骤S12，主机接收USB设备响应所述获取指令而发送的用户信息；
USB设备接收到获取指令后，响应该获取指令，将用户信息发送至主机，以使主机获得USB设备的所有用户。
步骤S13，主机在侦测到用户输入验证信息时，将用户输入的所述验证信息发送至USB设备，供USB设备根据所述验证信息确定用户权限并根据所述用户权限设置相应的功能配置信息；
主机可通过屏幕显示、语音播报等方式展示该USB设备的用户账号或其他用户信息以供用户选择一用户账号进行登录。用户可通过按键、手势、语音、文字输入、采集指纹等方式输入验证信息。
主机在侦测到用户输入验证信息时，将用户输入的验证信息发送至USB设备，USB设备根据该验证信息，对用户的身份进行验证，在用户输入的验证信息通过USB设备的验证时，USB设备确定该用户的用户权限，并根据该用户权限设置相应的功能配置信息，在用户输入的验证信息未通过USB设备的验证时，不执行下述步骤，或者，反馈主机验证失败并请求主机重新进行验证。在一些实施例中，USB设备可将验证信 息与用户权限的验证信息进行匹配，在存在用户权限的验证信息与用户输入的验证信息匹配时，确定与用户输入的验证信息匹配的用户权限为该用户的用户权限；在不存在用户权限的验证信息与用户输入的验证信息匹配时，确定该用户的用户权限为最低用户权限。
USB设备设置用户权限相应的功能配置信息的方法可以是：预置映射表，该映射表中包含用户权限与各功能的映射关系，根据用户权限可查找到该用户权限对应的功能，USB设备将查找到的这些功能的配置信息作为功能配置信息；或者，可以是其他任何适用的方法。
步骤S14，主机接收USB设备发送的所述功能配置信息。
在一些实施例中，也可以是通过主机确定用户权限。例如，主机侦测到用户输入验证信息时，根据该验证信息确定用户权限；主机发送携带用户权限的获取指令至USB设备，USB设备响应该获取指令，根据该用户权限设置相应的功能配置信息，并发送该功能配置信息至主机，主机接收该功能配置信息。
参照图3，图3为本发明USB设备的驱动方法第三实施例的流程示意图。
本发明USB设备的驱动方法第三实施例中，本实施例在第一实施例、第二实施例的基础上，所述步骤S20之后，所述USB设备的驱动方法包括：
步骤S30，在主机侦测到用户切换所述用户权限至新的用户权限的操作，且侦测到用户输入新的验证信息时，将用户输入的所述新的验证信息发送至USB设备，供USB设备根据所述新的验证信息确定新的用户权限并根据所述新的用户权限设置相应的新的功能配置信息；
主机可预先设置虚拟按钮获取其他切换标识供用户进行切换用户权限至新的用户权限，当然，用户切换用户权限至新的用户权限的操作并不限于此，还可以是任何适用的方式。
用户进行切换用户权限至新的用户权限的操作，并输入新的验证信息，主机将用户输入的新的验证信息发送至USB设备，USB设备根据新的验证信息重新确定新的用户权限并根据新的用户权限设置相应的新的功能配置信息。
其中，USB设备根据新的验证信息重新确定新的用户权限的方式与上述第二实施例的方法相同，在此不作赘述。
同样，USB设备根据新的用户权限设置相应的新的功能配置信息的方式也与上述第二实施例的方法可以相同，但本实施例中，USB根据新的用户权限设置相应的新的功能配置的方式也可以是：将当前用户权限对应的功能与新的用户权限对应的功能进行比较，添加或者删除部分功能，从而得到新的用户权限对应的新的功能配置信息。
步骤S40，主机接收USB设备发送的所述新的功能配置信息；
步骤S50，主机根据所述新的功能配置信息，重新生成与所述新的功能配置信息对应的功能端口。
主机根据新的功能配置信息，重新生成与新的功能配置信息对应的功能端口的方式与上述第二实施例的方法可以相同，本实施例中，主机根据新的功能配置信息，重新生成与新的功能配置信息对应的功能端口的方法也可以是：根据新的功能配置信息对应的功能端口与当前启用的功能端口进行比较，根据新的功能配置信息添加或删除部分功能端口，得到与新的功能配置信息对应的功能端口。
本实施例中，也可以是通过主机确定新的用户权限，其方法与上述第二实施例的方法相同，在此不作赘述。
本实施例在用户进行用户权限的切换时，USB设备可重新设置新的功能配置信息，而主机也可根据新的功能配置信息生成对应的功能端口。本实施例在用户进行用户权限的切换时，不需要重启USB PHY(Universal Serial Bus physical layer，通用串行总线物理接口)，使得切换过程的效果更平滑、更高效。
本发明一优选实施例中，若用户切断主机与USB设备的连接，并重新将USB设备与主机进行连接后，主机重复执行步骤S10和步骤S20。
本发明一优选实施例中，所述USB设备的驱动方法还包括：
主机在侦测到用户对当前的用户权限和/或用户信息进行修改、添加或删除操作时，将用户进行完修改、添加或删除操作后得到的新的用户权限和/或新的用户信息发送至USB设备供USB设备进行用户权限和/或用户信息的更新。
本实施例在用户权限和/或用户信息被修改、删除或添加时，可使新的用户权限和/或用户信息在主机与USB设备中同步。
下面举两个本发明USB设备的驱动方法的应用实例帮助理解，但并不用于限定本发明。
例一、USB设备为手机，该手机中预先设置有三种用户权限，分别为“Administrator”、“Guest1”、“Guest2”，Administrator的权限对应的功能为读写、电话本、信息备份，Guest1的权限对应的功能为电话本、信息备份，Guest2的权限对应的功能为信息备份。该手机与主机连接后，主机发送获取指令至手机，手机响应该获取指令，并发送用户信息至手机，该用户信息包括“Administrator”、“Guest1”、“Guest2”三个用户账号，主机展示该三个用户账号，用户若选择“Administrator”并输入相应密码一，主机发送该密码一至手机，手机验证该密码是否正确，若正确，则查找Administrator对应的功能，得到读写、电话本、信息备份三种功能，手机将这三种功能的配置信息发送至主机，例如，读写功能对应的配置信息为手机的存储空间信息，手机根据这三种功能的配置信息，生成这三种功能对应的功能端口，例如，手机根据手机的存储空间信息，生成虚拟的MASS STORAGE设备并生成相应的功能端口，用户通过虚拟的MASS STORAGE设备对手机进行读写操作。而对应于Guest1、Guest2的权限范围并不包括读写，因此，主机不会提供虚拟的MASS STORAGE设备及对应的端口。
例二、USB设备是自带移动数字电视解码芯片的多功能USB设备，主机设置于电视机中，该USB设备中预先设置有两种用户权限，分别为“Administrator”、“TV Viewer(电视机观看者)”，Administrator的权限对应的功能包括所有USB设备支持的功能，TV Viewer的权限对应的功能仅为与移动数字电视功能相关的功能，当USB设备与电视机连接时，用户以Administrator的身份登录，即USB设备确定用户的用户权限为Administrator，此处具体如何确定用户的权限可由上述实施例及例一中可获知，此处不作赘述。若用户只想观看数字电视，即只需要TV Viewer的权限，则进行用户权限的切换操作，将Administrator切换为TV Viewer，并输入TV Viewer的验证信息，主机将该验证信息发送至USB设备，USB设备根据该验证信息确定当前用户的权限为TV Viewer，并设置仅包括与移动数字电视功能相关的功能配置信息，并将该与移动数字电视功能相关的功能配置信息发送至USB设备，USB设备根据该功能配置信息，重新生成与移动数字电视功能相关的功能接口，而删除其他功能接口。
本发明实施例进一步提供一种USB设备的驱动方法。
参照图4，图4为本发明USB设备的驱动方法第四实施例的流程示意图。
本发明USB设备的驱动方法第四实施例中，该USB设备的驱动方法包括：
步骤S100，在主机与USB设备建立连接后，USB设备获取用户权限，并根据用户权限设置功能配置信息；
主机在与USB设备建立连接后，可由主机获取用户的用户权限，也可由USB设备获取用户的权限，获取用户权限的方法可以是通过密码验证、人脸识别、手势验证、声音验证、指纹验证等方式进行。其中，用户权限可预先设置，根据用户的需求，可设置为Administrator(管理员)、Guest(访客)，也可设置为多个用户权限等级，本发明对此不作限定。
功能配置信息是USB设备根据用户权限设置的，功能配置信息包括用户权限可使用的功能端口的配置。
步骤S200，USB设备发送所述功能配置信息至主机，供主机根据所述功能配置信息生成与所述功能配置信息对应的功能端口。
由于功能配置信息是由USB设备根据用户权限设置的，因此，主机根据该功能配置信息对应生成的功能端口即为用户权限对应的功能端口。
主机根据功能配置信息生成与该功能配置信息对应的功能端口的方法与现有技术相似，在此不作赘述。
本实施例USB设备根据用户权限设置相应的功能配置信息，主机根据USB设备设置的功能配置信息生成功能端口，因此，本实施例中，对于不同的用户权限，该用户可使用的功能端口是不同的，即用户可使用的功能也是不同的，因此，能提升USB设备的安全性，且功能端口的配置更灵活；此外，根据一些用户权限仅对应生成部分功能端口，USB设备不需要同时在主机上开启其所有的功能端口，因此，可提升USB设备的性能、降低功耗。
参照图5，图5为本发明USB设备的驱动方法第五实施例的流程示意图。
本发明USB设备的驱动方法第五实施例中，本实施例在第四实施例的基础上，所述步骤S100包括：

在主机与USB设备建立连接后，或者，在主机与USB设备重新建立连接后，主机发送获取指令至USB设备。
步骤S120，USB设备响应所述获取指令并发送用户信息至主机；
USB设备接收到获取指令后，响应该获取指令，将用户信息发送至主机，以使主机获得USB设备的所有用户。
步骤S130，USB设备接收主机在侦测到用户输入验证信息时发送的所述验证信息；
主机可通过屏幕显示、语音播报等方式展示该USB设备的用户账号或其他用户信息以供用户选择一用户账号进行登录。用户可通过按键、手势、语音、文字输入、采集指纹等方式输入验证信息。
主机在侦测到用户输入验证信息时，将用户输入的验证信息发送至USB设备。
步骤S140，USB设备根据所述验证信息确定用户权限并根据所述用户权限设置相应的功能配置信息。
USB设备根据该验证信息，对用户的身份进行验证，在用户输入的验证信息通过USB设备的验证时，USB设备确定该用户的用户权限，并根据该用户权限设置相应的功能配置信息，在用户输入的验证信息未通过USB设备的验证时，不执行下述步骤，或者，反馈主机验证失败并请求主机重新进行验证。在一些实施例中，USB设备可将验证信息与用户权限的验证信息进行匹配，在存在用户权限的验证信息与用户输入的验证信息匹配时，确定与用户输入的验证信息匹配的用户权限为该用户的用户权限；在不存在用户权限的验证信息与用户输入的验证信息匹配时，确定该用户的用户权限为最低用户权限。
USB设备设置用户权限相应的功能配置信息的方法可以是：预置映射表，该映射表中包含用户权限与各功能的映射关系，根据用户权限可查找到该用户权限对应的功能，USB设备将查找到的这些功能的配置信息作为功能配置信息；或者，可以是其他任何适用的方法。
在一些实施例中，也可以是通过主机确定用户权限。例如，主机侦测到用户输入验证信息时，根据该验证信息确定用户权限；主机发送携带用户权限的获取指令至USB设备，USB设备响应该获取指令，根据该用户权限设置相应的功能配置信息，并发送该功能配置信息至主机，主机接收该功能配置信息。

用户进行切换用户权限至新的用户权限的操作，并输入新的验证信息，主机将用户输入的新的验证信息发送至USB设备。
步骤S400，USB设备根据所述新的验证信息确定新的用户权限并根据所述新的用户权限设置相应的新的功能配置信息；
其中，USB设备根据新的验证信息重新确定新的用户权限的方式与上述第五实施例的方法相同，在此不作赘述。
同样，USB设备根据新的用户权限设置相应的新的功能配置信息的方式也与上述第五实施例的方法可以相同，但本实施例中，USB根据新的用户权限设置相应的新的功能配置的方式也可以是：将当前用户权限对应的功能与新的用户权限对应的功能进行比较，添加或者删除部分功能，从而得到新的用户权限对应的新的功能配置信息。
步骤S500，USB设备发送所述新的功能配置信息至主机，供主机根据所述新的功能配置信息，重新生成与所述新的功能配置信息对应的功能端口。
