相关申请的交叉引用
本申请基于申请号为201611087145.5、申请日为2016年12月01日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此引入本申请作为参考。
本发明涉及通用串行总线(USB,Universal Serial Bus)通信技术,尤其涉及一种传输模式配置方法、装置及系统、计算机存储介质。
目前,带有USB接口的电子产品上具有的USB主机控制器越来越多。比如,一些电脑具有USB3.0和USB2.0两种类型的主机控制器。从而也就存在用户在不同USB协议的主机控制器上使用USB产品的问题。在使用过程中,发明人发现,部分电子产品厂商的USB 3.0主机控制器驱动做的不够完善,目前USB 3.0主机控制器驱动形成一个标准是比较困难的,USB3.0设备要适配各个厂商的USB 3.0主机控制器驱动也就会存在一些问题,并且USB3.0设备的兼容性不好,如将其插到具有USB2.0主机控制器的电脑上,有时无法正常工作。
在使用过程中,发明人还发现,USB设备采用的是USB3.0数据线,插入的也是具有USB 3.0主机控制器的电子产品,但是USB设备却上报的是USB2.0的传输模式,事实上应该上报为USB3.0的传输模式。当电子产品的主机既支持具有USB2.0功能的设备,又支持具有USB3.0功能的设备,USB设备从USB3.0主机控制器上拔出后,插到USB2.0主机控制器上,主机上的操作联网的会出现打开驱动端口失败或者串口驱动功能异常的问题。
反之,从USB2.0主机控制器上拔出后,插到USB3.0主机控制器上,USB设备会上报成USB2.0,也就是有可能上报的USB相关信息错误,导致设备设置的传输模式失效。
为了验证USB信息上报失败导致设备配置传输模式失效是否和操作系统有一定的关系。发明人在对USB3.0设备的使用过程中,针对此情况,需要在windows操作系统进行测试,测试过程中主要涉及到的操作系统包括windows XP系统、windows7系统、windows 8系统、windows 10系统等,在这些操作系统的32位和64位都进行了摸底,测试的结果表明若电脑具有支持USB3.0主机控制器,都会出现USB信息上报失败的现象。若USB信息上报失败的现象只在windows XP系统上出现,也可以不做处理的。毕竟目前市场上主流操作系统没有包含windows XP系统,但是市场主流的windows操作系统上均有此失败现象,意味着该现象需要给予重视。因此,在windows操作系统进行了多方面的摸底测试,发现USB设备在电脑的多种行为下均会出现这类异常的现象。
因此,在拔插设备或者电脑睡眠唤醒的过程中,主机上的操作联网的软件容易出现异常、驱动端口功能异常或者USB传输模式识别错乱的情况,这些问题亟待解决。

等问题。
实施例五
本实施例提供了一种传输模式配置系统,所述传输模式配置系统,包括目标主机和USB设备;其中:
所述目标主机,配置为获取USB设备基于传输模式信息获取指令上报的USB传输模式信息;当所述USB传输模式信息与目标主机记录的USB传输模式信息不一致时,将所述目标主机记录的USB传输模式信息修改为USB设备侧上报的USB传输模式信息;基于修改后的USB传输模式信息进行传输模式配置;

在一实施例中,所述目标主机,还配置为检测到USB设备插入目标主机时,若判断所述USB设备为非首次插入,向所述USB设备发送传输模式信息获取指令。
在一实施例中,所述目标主机,还配置为判断所述USB传输模式信息与目标主机记录的USB传输模式信息是否一致。
具体地,所述目标主机包括图3所示的传输模式配置装置,所述USB设备包括图4所示的传输模式配置装置,在此不再赘述。
下面结合具体实施场景对本发明实施例的传输模式配置方法做详细描述。
为方便描述,将上述图3中所示的应用目标主机侧的传输模式配置装置记为主机模块,其中,所述主机模块中包括传输模式识别模块以及用户界面控制模块。所述传输模式识别模块包括第一发送单元31、第一接收单元32、识别单元33、第一配置单元34、第一通信单元35。
为方便描述,将上述图4中所示的应用USB侧的传输模式配置装置记为USB板侧模块,其中,所述USB板侧模块包括内核子模块和功能子模块;所述内核子模块包括第二接收单元41、第二发送单元42、第二通信单元44,所述功能子模块包括第二配置单元43。
本发明实施例还记载了一种完整的传输模式配置装置,所述传输模式配置装置包括:主机模块和USB板侧模块。
其中,主机模块和USB板侧模块构成一个完整的USB传输模式配置装置。该装置通过在目标主机上安装主机模块,随着主机模块的安装完成,USB传输模式识别模块也就安装到主机系统上,使用具备本实施例所述USB板侧模块的数据卡类终端设备,即可构成一个不受主机系统影响,能够自动和识别目标主机所支持的USB传输模式,同时判断设备可以使用的传输模式类型的识别系统。
其中,主机模块中的传输模式识别模块只需要在目标主机中安装一次,即可完成本实施例所述装置在目标主机中的安装过程。在装置后续的使用和运行中,全部主要工作只需要在装置的传输模式识别模块与USB板侧模块内部进行通信可以完成此配置的功能,传输模式识别模块通过发送一些标准的USB请求到USB板侧模块获取设备的传输模式信息,根据设备支持的传输模式进行判断并清理主机上记录上次设备插入到主机上的信息,并根据设备的传输模式信息将USB板侧的信息填写主机操作系统中,这样比较快速实现设备的传输模式写入到主机上和端口枚举。如果出现本发明背景技术中提到的问题,这样可以通过目标主机上的传输模式识别模块发送一些标准USB请求指令将传输模式信息和枚举信息更好地记录到主机上,以避免设备枚举信息和传输模式上报错误,导致用户无法继续使用上网或者速率不符合用户的要求。
为实现这一功能,主机模块包含传输模式识别模块。传输模式识别模块包含一些发送标准的USB请求指令等,本发明重点阐述此模块功能如何
实现。设备首次使用插入到主机系统上采取的是初始传输模式,初始传输模式为USB板侧模块根据主机的主机控制器是USB2.0或USB 3.0进行适配后,选择一种主动上报的速度传输模式。采用本方案后可以为用户提供良好的新旧产品继承、兼容能力。
本实施例所述装置主机模块的传输模式识别模块的主要作用是同本实施例所述装置中的USB板侧模块的内核层子模块进行通信、提供USB控制消息的发送,传输模式识别模块和USB板侧模块建立通信默认管道连接,管理速度传输模式识别的控制通路,完成主机模块和USB板侧模块的连接阶段。
本实施例提供的技术方案,实现了USB速度传输模式自动识别和适配,灵活、方便,更解决在传输模式识别错误的情况下需要重启设备或者插拔设备到正常的端口的问题。通过本发明实施例提供的技术方案,速度传输模式识别过程中,不会出现USB设备无法使用的情况,不需要USB设备反复插拔的工作,节省用户的时间;在目标主机上只需将主机安装一次,可以和USB设备交互进行适配数据卡产品的传输模式识别和配置;提升了USB设备的兼容性和稳定性。

步骤603:该传输模式识别模块初始化完成后,向USB设备发送传输模式信息获取指令,来完成获取USB设备板侧的USB信息。
这里,所述传输模式信息获取指令可以是标准USB请求指令,如USB设备描述符请求指令。所述传输模式信息获取指令还可以是自定义USB请求指令,如携带有获取USB传输模式信息指示的SCSI指令。

步骤702:USB板侧模块中的内核子模块初始化完成后,主机模块中的传输模式识别模块按照实施例七完成初始化工作。
具体地,USB板侧模块中的内核子模块初始化完成后USB设备就可以通过功能子模块完成枚举工作。
步骤703:当USB板侧模块中的内核子模块和主机模块侧的传输模式
识别模块初始化完成后,这样两者可以建立通信和工作了。
实施例九
图8为本实施例提供的配置通信工作的流程示意图,如图8所示,主机模块和USB板侧模块首次建立连接的初始化以及切换适配速度模式,最终建立某个速度传输模式过程。图8中的第一个虚线上面部分表示目标主机安装软件和USB板侧模块安装初始化完成的过程,图7已经详细介绍这个流程,第一虚线和第二个虚线中间区域表示USB板侧模块、传输模式识别模块以及主机系统进行速度模式适配的过程,第二个虚线下面的区域表示适配完成后建立某种速度模式连接通信。
步骤801:当USB设备插入到目标主机后,USB设备根据USB标准协议完成USB内核子模块的初始化工作。
步骤802:USB板侧模块中的内核子模块初始化完成后,USB设备就可以通过USB板侧模块中的功能子模块完成枚举工作,这时可以根据设备枚举的大容量存储设备安装主机模块的内容,待安装完成后,传输模式识别模块就会初始化完成,或者采用第二种方法即通过官方网站的方式下载该传输模式识别模块单独安装来进行初始化工作。
步骤803:当USB板侧模块中的内核子模块和主机模块中的传输模式识别模块初始化完成后,两者可以通过USB标准请求指令建立通信和工作了。
步骤804:USB板侧模块中的内核子模块初始化完成后,会通过功能子模块向操作系统上报信息,此操作系统会记录USB相关信息。
步骤805:主机模块中的传输模式识别模块通过调用操作系统的相关函数读取内核子模块上报给主机系统内存中的相关数据。
步骤806:主机模块中的传输模式识别模块获取USB设备的USB相关信息,同步比较操作系统记录该USB设备首次使用时保存到内存的USB相关信息,根据比较结果清理目标主机上记录的上次设备插入到主机上的
USB相关信息,并将USB板侧的传输模式信息上报给主机操作系统。
如此,比较快速地实现USB设备的传输模式写入到目标主机上和端口枚举。
这样,目标主机与USB设备就可以完成某一种速度模式建立,进行通信工作了。
实施例十
图9为本实施例提供的传输模式配置的工作流程示意图,如图9所示该流程主要包括:
步骤901、目标主机与USB设备建立连接,并按照初始传输模式进行数据传输。
在一具体实施方式中,待USB设备插入到目标主机,目标主机在短时间内初始化完成,目标主机同USB设备建立的初始传输模式连接。目标主机和USB设备建立通信连接后进行正常的数据交互。
步骤902、主机模块中的传输模式识别模块向USB设备发送传输模式信息获取指令。
这里,所述传输模式信息获取指令可以是USB标准请求指令或者自定义USB请求指令。本实施例中,所述传输模式信息获取指令主要是获取USB传输模式相关信息的,USB设备基于所述传输模式信息获取指令上报相关USB传输模式信息。
当然,传输模式信息获取指令可通过多种方式实现,本实施例中仅以USB标准请求指令或者自定义USB请求指令为例进行说明。
步骤903、USB设备接收目标主机的传输模式信息获取指令。
USB设备收到目标主机发送的传输模式信息获取指令后,将对所述传输模式信息获取指令进行解析,同步主机模块中的传输模式识别模块读取主机系统中USB传输模式信息,该方法是通过USB的厂商标识、产品表示以及光盘序列号等信息遍历查询保存该USB设备的传输模式参数信息,这
些USB设备的传输模式参数信息主要包含bcdUSB、bMaxPacketSize0、设备驱动能力参数。
步骤904、主机模块中的传输模式识别模块根据步骤903获取的相关信息,进行判断;该传输模式识别模块判断是USB设备侧上报的信息和主机系统记录该设备的信息是否一致,如果一致,跳至步骤905;如不一致,跳至步骤906。
同步,传输模式识别模块会通过调用主机系统的函数获取主机保存该设备的USB传输模式信息,这样进行对比两者是否一致,若不一致,USB传输模式识别模块会利用主机系统的函数清除主机系统的信息,直接写入USB设备上报来的信息,这样可以实现USB传输模式的正确读写。USB设备完成与目标主机适配的传输模式配置,进而建立该速度传输模式的Interfaces(Interrupt Bulk IN/OUT Pipe连接)通信,这样USB设备根据该速度传输模式正常工作。
步骤905、主机模块中的传输模式识别模块将相关信息报送给主机系统不修改任何信息,USB设备可以直接上报相关信息,并跳至步骤908。
步骤906、主机模块中的传输模式识别模块根据当前USB板侧模块的USB信息修改主机系统保存的USB信息。
步骤907、USB设备和目标主机基于USB传输模式信息进行传输模式配置。
本实施例中,将传输模式识别模块预设在目标主机中,适用于传输模式固定的场景中,比如USB3.0和USB2.0的传输模式自动切换;比如USB2.0和USB1.0的模式自动切换,均可以利用该模块来进行识别判断。
本实施例中,根据实际情况动态获取,适用于更灵活的场合。检测主机端口工作在USB3.0或者USB2.0时,将所述速率参数设置为USB2.0或者USB3.0的速率参数,使用传输模式识别模块可以更加准确地获取USB板侧信息和改变系统内存的保留信息,不至于USB设备出现枚举失败或者
主机不再获取USB设备的一些信息导致USB设备功能异常。
使用本发明所述技术方案的优点主要体现如下几点:
1、可以避免USB传输模式识别出现错误,不至于USB板侧上报成USB3.0,由于主机系统记录的该设备支持USB2.0,而最后设备只能上报USB2.0,导致USB3.0失效;或者设备插到USB2.0的主机控制器上,应该上报的USB2.0信息,但由于主机系统记录的该设备是USB3.0的设备,导致信息传输错误,出现驱动异常。
2、采取本发明所述技术方案,可以避免设备枚举时将USB信息清空,同时传输模式识别模块可以快速读取USB板侧的USB信息,将相关信息写入到主机系统对应的内存中,这样设备的枚举会变快,而不会影响用户的等待时间。
3、在USB2.0和USB3.0的相互切换过程,使用本发明所述技术方案也可以快速识别,不会引起设备驱动出现异常的。
