Description

电子设备以及向直连的另一电子设备提供数据的方法
本申请要求在2016年4月29日提交中国专利局、申请号为201610285308.4、发明名称为“电子设备、向直连的另一电子设备提供数据的方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及智能设备技术领域，例如涉及第一电子设备向直连的第二电子设备提供数据的方法和第一电子设备。
背景技术
通用串行总线(Universal Serial Bus，USB)是一种主从结构，主机为Host，从机为Device，USB的数据交换只能发生在主机(Host)和设备(Device)之间，主机(Host)和主机(Host)、以及设备(Device)和设备(Device)之间不能互连，所有的数据传输都由主机(Host)主动发起，而设备(Device)只是被动的负责应答，例如，在读数据时，主机(Host)先发出读命令，设备(Device)收到该命令后，才返回数据。通常情况下，电脑为主机(Host)，其它USB外设为设备(Device)。
USB OTG(On-The-Go)标准完全兼容USB2.0标准，可以利用OTG标准在没有电脑的情况下，实现其它USB外设之间的数据传送。如果相连的两个USB外设都是OTG双功能设备(Dual-Role Device，DRD)，都可以在Host/Device之间切换，将两者用OTG数据线连接，就可以读取对方设备的SD卡中的数据，但仍然无法识别到对方设备的用户数据分区(USER DATA)，也不能从对方设备的用户数据分区(USER DATA)中读取数据。
发明内容
本申请提供向直连的电子设备提供数据的方法、以及相关电子设备，使得电子设备能够读取直连的另一电子设备的用户数据分区(USER DATA)。
根据本申请实施例的第一方面，提供了一种第一电子设备向直连的第二电子设备提供数据的方法，应用于第一电子设备中，包括：
接收设置为OTG device模式的命令，将所述第一电子设备设置为OTG device 模式，以使得与所述第一电子设备通过OTG数据线连接的第二电子设备将自身设置为OTG host模式；
接收从所述第二电子设备发来的读取所述第一电子设备的用户数据分区的请求；以及
将所述第一电子设备的用户数据分区枚举为一个U盘，以供所述第二电子设备直接从枚举出的U盘中读取用户数据。
可选地，所述第一电子设备为智能手机。
可选地，所述将第一电子设备设置为OTG device模式，包括：通过硬件控制电路控制相关寄存器的数据，以将所述第一电子设备设置为OTG device模式。
根据本申请实施例的第二方面，提供了一种第一电子设备，包括：模式控制模块、请求接收模块、以及枚举模块；
所述模式控制模块，设置为接收设置为OTG device模式的命令，将所述第一电子设备设置为OTG device模式，以使得与所述第一电子设备通过OTG数据线连接的第二电子设备将自身设置为OTG host模式；
所述请求接收模块，设置为接收从所述第二电子设备发来的读取所述第一电子设备的用户数据分区的请求；以及
所述枚举模块，设置为将所述第一电子设备的用户数据分区枚举为一个U盘，以供所述第二电子设备直接从枚举出的U盘中读取用户数据。
可选地，所述第一电子设备为智能手机。
可选地，所述模式控制模块将所述第一电子设备设置为OTG device模式，包括：通过硬件控制电路控制相关寄存器的数据，以将所述第一电子设备设置为OTG device模式。
根据本申请实施例的第三方面，提供了一种第一电子设备，包括至少一个处理器；以及与所述至少一个处理器通信连接的存储器，其中，所述存储器存储有可被所述至少一个处理器执行的指令，所述指令用于控制所述处理器进行操作以执行任一项所述的方法。
根据本申请实施例的第四方面，还提供了一种非暂态计算机可读存储介质，其中，所述非暂态计算机可读存储介质存储计算机指令，所述计算机指令用于使所述计算机执行上述的任一项所述的方法。
根据本申请实施例的第五方面，还提供了一种计算机程序产品，包括存储在非暂态计算机可读存储介质上的计算程序，所述计算机程序包括程序指令，当所述程序指令被计算机执行时，使所述计算机执行上述任一项所述的方法。
本申请实施例利用了电子设备的OTG功能，将第一电子设备设置为OTG device模式，如果接收到与该第一电子设备直连的第二电子设备读取用户数据分区的请求，就将第一电子设备自身的用户数据分区枚举为一个U盘，这样第二电子设备就可以从枚举出的U盘中读取用户数据，方便了用户的使用。

<实施例一>
参考图1所示，本申请实施例一提供了一种第一电子设备向直连的第二电子设备提供数据的方法。
第一电子设备和第二电子设备直连，可以是指第一电子设备和第二电子设备之间不经过第三电子设备(例如电脑)中转，而是第一电子设备和第二电子设备通过OTG数据线直接连接。
该方法包括步骤110-步骤130。
在步骤110中，第一电子设备接收用户发来的设置成OTG device模式的命令，将第一电子设备设置为OTG device模式，由于USB OTG的协商机制，可以使得与第一电子设备通过OTG数据线连接的第二电子设备设置为OTG host模式。在步骤110完成后，第一电子设备和第二电子设备符合USB OTG的主从结构，其中第一电子设备为Device，第二电子设备为Host。
在步骤120中，接收从第二电子设备发来的读取第一电子设备的用户数据分区(USER DATA)的请求。
在步骤130中，接收到所述请求后，将第一电子设备的用户数据分区(USER DATA)枚举为一个U盘，以供第二电子设备直接从枚举出的U盘中读取用户数据。
可选地，在步骤110中，可以通过硬件控制电路控制相关寄存器的数据，从而将第一电子设备设置为OTG device模式。本申请还可以采用别的方式将第一电子设备设置为OTG device模式。
本申请实施例利用了电子设备的OTG功能，将第一电子设备设置为OTG device模式，如果接收到与该第一电子设备直连的第二电子设备读取用户数据分区的请求，就将第一电子设备自身的用户数据分区枚举为一个U盘，这样第二电子设备就可以从枚举出的U盘中读取用户数据，方便了用户的使用。
可选地，第一电子设备和第二电子设备可以为智能手机，智能手机多支持OTG host/device模式，可以利用本方法将旧智能手机中的用户数据区轻易地读取到新智能手机中，提升了用户更换新智能手机的容易性。
<实施例二>
参考图2所示，本申请实施例二提供了第一电子设备10。第一电子设备10 和第二电子设备直连，可以是指第一电子设备10和第二电子设备之间不经过第三电子设备(例如电脑)中转，而是第一电子设备10和第二电子设备通过OTG数据线直接连接。
第一电子设备10包括模式控制模块11、请求接收模块12、以及枚举模块13。
模式控制模块11，设置为接收设置为OTG device模式的命令，将第一电子设备10设置为OTG device模式，由于USB OTG的协商机制，会使得与第一电子设备10通过OTG数据线连接的第二电子设备设置为OTG host模式。这一过程完成后，第一电子设备和第二电子设备符合USB OTG的主从结构，其中第一电子设备为Device，第二电子设备为Host。
请求接收模块12，设置为接收从第二电子设备发来的读取第一电子设备10的用户数据分区的请求。
枚举模块13，设置为在请求接收模块12接收到所述请求后，将第一电子设备10的用户数据分区枚举为一个U盘，以供第二电子设备直接从枚举出的U盘中读取第一电子设备10的用户数据。
可选地，模式控制模块11可以通过硬件控制电路控制相关寄存器的数据，从而将第一电子设备10设置为OTG device模式。本申请实施例还可以采用别的方式将第一电子设备10设置为OTG device模式。
本申请实施例利用了电子设备的OTG功能，将第一电子设备设置为OTG device模式，如果接收到与该第一电子设备直连的第二电子设备读取用户数据分区的请求，可以将第一电子设备自身的用户数据分区枚举为一个U盘，这样第二电子设备就可以从枚举出的U盘中读取用户数据，方便了用户的使用。
可选地，第一电子设备和第二电子设备可以为智能手机，智能手机多支持OTG host/device模式，可以利用本方法将旧智能手机中的用户数据区轻易地读取到新智能手机中，提升了用户更换新智能手机的容易性，驱动用户购买智能手机。
