Description

一种USB设备的配置方法及主机Configuration method and host of USB device 技术领域Technical field
本申请涉及但不限于数据通信技术，尤其是一种USB设备的配置方法及主机。The present application relates to, but is not limited to, data communication technology, and in particular, to a USB device configuration method and a host.
背景技术Background technique
近几年，用户对于USB(Universal Serial Bus，通用串行总线)接口的使用越来越频繁，选择性也越来越多。目前，越来越多的电脑厂商在主板芯片上增加了USB3.0主机控制器，结合之前的USB1.0、USB1.1以及使用最为广泛的USB2.0接口，接口标准从当初的OHCI(Open Host Controller Interface，开放式主机控制器接口)、UHCI(Universal Host Controller Interface，通用主机控制器接口)到后来的EHCI(Enhanced Host Controller Interface，增强主机控制器接口)，再到最新的xHCI(Extensible Host Controller Interface，可扩展的主机控制器接口)。在USB设备的使用上，不同的接口标准也会带来影响USB设备使用的情况。In recent years, users have become more and more frequently using USB (Universal Serial Bus) interfaces and have more and more options. At present, more and more computer manufacturers have added a USB3.0 host controller to the motherboard chip, combining the previous USB1.0, USB1.1 and the most widely used USB2.0 interface. The interface standard is from the original OHCI (Open Host Controller Interface, Open Host Controller Interface, UHCI (Universal Host Controller Interface) to later EHCI (Enhanced Host Controller Interface), to the latest xHCI (Extensible Host) Controller Interface, an expandable host controller interface). In the use of USB devices, different interface standards can also affect the use of USB devices.
USB设备在插入主机的USB接口之后，主机会轮询它的根Hub的状态，判断是否有设备(包括子Hub和子Hub上的设备)连接；接着主机会进行一系列的配置操作使得USB设备正常枚举。在USB设备的配置过程中，在主机使用不同的操作系统下，USB设备需要使用不同的工作模式，以满足上层业务的需求。其中，主机使用的操作系统包括：Windows操作系统和非Windows操作系统(Mac操作系统和Linux操作系统)。当主机使用Windows操作系统时，USB设备需要工作在第一工作模式下，主机需要对第一工作模式下的USB设备进行配置；当主机使用非Windows操作系统时，USB设备需要工作在第二工作模式下，主机需要对第二模式下的USB设备进行配置。例如，当主机使用Windows操作系统时，当USB设备插入主机后，主机与USB设备会交互微软描述符，若USB设备收到主机下发的微软描述符，则表明主机使用的操作系统是Windows系统，若USB设备未收到主机下发的微软描述符，则表明主机使用的操作系统是非Windows系统。After the USB device is plugged into the USB interface of the host, the host polls the status of its root hub to determine whether there is a device (including the device on the child hub and the child hub). Then the host performs a series of configuration operations to make the USB device normal. enumerate. In the configuration process of the USB device, the USB device needs to use different working modes to meet the requirements of the upper layer service when the host uses different operating systems. Among them, the operating system used by the host includes: Windows operating system and non-Windows operating system (Mac operating system and Linux operating system). When the host uses the Windows operating system, the USB device needs to work in the first working mode, and the host needs to configure the USB device in the first working mode; when the host uses the non-Windows operating system, the USB device needs to work in the second work. In the mode, the host needs to configure the USB device in the second mode. For example, when the host uses the Windows operating system, when the USB device is plugged into the host, the host and the USB device interact with the Microsoft descriptor. If the USB device receives the Microsoft descriptor sent by the host, the operating system used by the host is the Windows system. If the USB device does not receive the Microsoft descriptor sent by the host, it indicates that the operating system used by the host is a non-Windows system.

步骤303、根据全部第一配置响应消息对USB设备进行配置。Step 303: Configure the USB device according to all the first configuration response messages.
在本发明的示例性实施例中，主机在接收到USB设备返回的全部第一配置响应消息之后，主机可以根据全部第一配置响应消息对USB设备进行配置。在主机对USB设备的配置过程中，主机与USB设备之间的交互主要包括：主机的操作系统的控制器驱动与设备的交互以及主机的功能驱动与USB设备之间的交互。只有两者交互完成，USB设备才能工作正常通信和使用。在本发明的示例性实施例中，主机对USB设备的配置过程主要是主机根据USB设备上报的接口类、接口子类、协议类等主要信息，选择合适的网卡类型和 驱动对USB设备进行适配和驱动加载。In an exemplary embodiment of the present invention, after receiving all the first configuration response messages returned by the USB device, the host may configure the USB device according to all the first configuration response messages. During the host-to-USB device configuration, the interaction between the host and the USB device mainly includes: interaction between the controller driver of the host operating system and the device, and interaction between the function driver of the host and the USB device. Only when the two are interactive, the USB device can work and communicate normally. In an exemplary embodiment of the present invention, the configuration process of the USB device by the host is mainly based on the main information such as the interface class, the interface subclass, and the protocol class reported by the USB device, and the appropriate network card type and driver are selected for the USB device. Match and drive loading.
根据上述的描述可知，通过上述的步骤301～303，主机可以先按照第一工作模式对应的第一配置方法对USB设备进行配置；当主机对USB设备配置失败时，主机可以控制USB设备将其工作模式从第一工作模式适配到第二工作模式，进而主机可以按照第二工作模式对应的第二配置方法对USB设备进行配置。According to the foregoing description, the host may first configure the USB device according to the first configuration method corresponding to the first working mode. When the host fails to configure the USB device, the host may control the USB device to The working mode is adapted from the first working mode to the second working mode, and the host can configure the USB device according to the second configuration method corresponding to the second working mode.
在本发明的示例性实施例中，主机在按照第一工作模式对应的第一配置方法对USB设备进行配置之后，主机可以先判断按照第一配置方法是否对USB设备配置成功；当主机按照第一配置方法对USB设备配置失败时，主机可以按照第二工作模式对应的第二配置方法对USB设备进行配置；当主机按照第一配置方法对USB设备配置成功时，主机可以结束对USB设备的配置流程。In an exemplary embodiment of the present invention, after the host configures the USB device according to the first configuration method corresponding to the first working mode, the host may first determine whether the USB device is successfully configured according to the first configuration method; When the configuration of the USB device fails, the host can configure the USB device according to the second configuration method corresponding to the second working mode.

As shown in FIG. 4, the method for determining whether the USB device is successfully configured may include steps 401 to 403.
步骤401、向USB设备发送USB自定义请求指令。Step 401: Send a USB custom request instruction to the USB device.
在本发明的示例性实施例中，主机在按照第一工作模式对应的第一配置方法对USB设备进行配置之后，主机可以向USB设备发送USB自定义请求指令，该USB自定义请求指令主要是用于获取USB设备配置完成信息的，USB设备收到该USB自定义请求指令后需要上报相关的USB信息。在本发明的示例性实施例中，USB自定义请求指令可以通过基于USB标准协议实现。基于USB标准请求扩展的USB自定义请求指令用于获取USB设备配置完成信息，USB自定义请求指令的格式需要符合USB标准协议，例如：USB自定义请求指令的格式可以是：“C0 01 ×× ×× 00 00 00 00”，其中“C0”表示USB自定义请求指令的方向是主机到USB设备，并且“C0”表示该指令是USB自定义请求指令；“01”表示获取配置完成消息。In an exemplary embodiment of the present invention, after the host configures the USB device according to the first configuration method corresponding to the first working mode, the host may send a USB custom request instruction to the USB device, where the USB custom request command is mainly For obtaining the configuration information of the USB device, the USB device needs to report the relevant USB information after receiving the USB custom request command. In an exemplary embodiment of the present invention, the USB custom request instruction may be implemented by a USB-based standard protocol. The USB custom request instruction based on the USB standard request extension is used to obtain the USB device configuration completion information, and the format of the USB custom request instruction needs to conform to the USB standard protocol. For example, the format of the USB custom request instruction may be: “C0 01 ×× × × 00 00 00 00", where "C0" indicates that the direction of the USB custom request instruction is the host to the USB device, and "C0" indicates that the instruction is a USB custom request instruction; "01" indicates that the configuration completion message is acquired.
步骤402、接收USB设备返回的USB自定义响应消息。Step 402: Receive a USB custom response message returned by the USB device.
在本发明的示例性实施例中，USB设备在接收到主机发送的USB自定义请求消息之后，USB设备将对该USB自定义请求指令进行解析，并将配 置完成信息携带在USB自定义响应消息中返回给主机；其中，USB自定义响应消息包括：USB已配置响应消息或者USB未配置响应消息。在本发明的示例性实施例中，USB自定义请求指令和配置完成信息都是主机和USB设备互相协商好的，USB设备向主机返回的USB自定义响应消息的格式也需要符合USB标准协议，比如：“00”表示USB已配置响应消息；“01”表示USB未配置响应消息。In an exemplary embodiment of the present invention, after receiving the USB custom request message sent by the host, the USB device parses the USB custom request command and carries the configuration completion information in the USB custom response message. Returned to the host; wherein the USB custom response message includes: a USB configured response message or a USB unconfigured response message. In an exemplary embodiment of the present invention, the USB custom request instruction and the configuration completion information are mutually negotiated between the host and the USB device, and the format of the USB custom response message returned by the USB device to the host also needs to comply with the USB standard protocol. For example: “00” indicates that the USB has configured a response message; “01” indicates that the USB is not configured with a response message.
步骤403、根据USB自定义响应消息判断是否对USB设备配置成功。Step 403: Determine, according to the USB custom response message, whether the USB device is successfully configured.
在本发明的示例性实施例中，主机可以根据USB设备返回的USB自定义响应消息判断是否对USB设备配置成功。在本发明的示例性实施例中，当USB自定义响应消息为USB已配置响应消息时，表明USB设备的驱动加载和安装正常，主机判定对USB设备配置成功；当USB自定义响应消息为USB未配置响应消息时，表明USB设备的驱动加载或安装不正常，主机判定对USB设备配置失败。In an exemplary embodiment of the present invention, the host may determine whether the USB device configuration is successful according to the USB custom response message returned by the USB device. In an exemplary embodiment of the present invention, when the USB custom response message is a USB configured response message, indicating that the driver loading and installation of the USB device is normal, the host determines that the USB device configuration is successful; when the USB custom response message is USB When the response message is not configured, it indicates that the driver of the USB device is not loaded or installed properly, and the host determines that the configuration of the USB device fails.
根据上述的分析可知，通过上述的步骤401～403，主机可以向USB设备发送USB自定义请求指令，然后主机根据接收到的USB自定义响应消息判断对USB设备是否配置成功。当主机对USB设备配置失败时，主机可以控制USB设备可以将其工作模式从第一工作模式适配到第二工作模式，进而主机可以按照第二工作模式对应的第二配置方法对USB设备进行配置。According to the above analysis, the host can send a USB custom request command to the USB device through the above steps 401-403, and then the host determines whether the USB device is successfully configured according to the received USB custom response message.

图5为本发明实施例中判断是否对USB设备配置成功的第二实现方法流程示意图。如图5所示，判断是否对USB设备配置成功的方法可以包括以下步骤：FIG. 5 is a schematic flowchart of a second implementation method for determining whether a USB device is successfully configured in an embodiment of the present invention. As shown in FIG. 5, the method for determining whether the USB device is successfully configured may include the following steps:
步骤501、向USB设备发送SCSI请求指令。Step 501: Send a SCSI request instruction to the USB device.
在本发明的示例性实施例中，主机在按照第一工作模式对应的第一配置方法对USB设备进行配置之后，主机可以向USB设备发送SCSI(小型计算机系统接口(Small Computer System Interface，SCSI)请求指令，该SCSI请求指令也是用于获取USB设备配置完成信息的，USB设备收到该SCSI请求指令后需要上报相关的USB信息。在本发明的示例性实施例中，SCSI请求指令可以通过SCSI协议来实现。主机可以和USB设备协商增加一个索引值表示获取配置完成消息的信息，USB设备收到该SCSI请求指令之后，USB 设备可以根据该索引值将配置完成信息上报给主机。In an exemplary embodiment of the present invention, after the host configures the USB device according to the first configuration method corresponding to the first working mode, the host may send the SCSI (Small Computer System Interface (SCSI)) to the USB device. Requesting an instruction, the SCSI request instruction is also used to obtain USB device configuration completion information, and the USB device needs to report related USB information after receiving the SCSI request instruction. In an exemplary embodiment of the present invention, the SCSI request instruction may pass SCSI. The protocol can be implemented. The host can negotiate with the USB device to add an index value to obtain the information about the configuration completion message. After the USB device receives the SCSI request command, the USB device can report the configuration completion information to the host according to the index value.
步骤502、接收USB设备返回的SCSI响应消息。Step 502: Receive a SCSI response message returned by the USB device.
在本发明的示例性实施例中，USB设备在接收到主机发送的SCSI请求指令之后，USB设备将对该SCSI请求指令进行解析，并将配置完成信息携带在SCSI响应消息中返回给主机；其中，SCSI响应消息包括：SCSI已配置响应消息或者SCSI未配置响应消息。在本发明的示例性实施例中，SCSI请求指令和配置完成信息都是主机和USB设备互相协商好的，USB设备向主机返回的SCSI响应消息的格式也需要符合SCSI标准协议。In an exemplary embodiment of the present invention, after receiving the SCSI request command sent by the host, the USB device parses the SCSI request command, and carries the configuration completion information in the SCSI response message and returns it to the host; The SCSI response message includes: a SCSI configured response message or a SCSI unconfigured response message. In an exemplary embodiment of the present invention, both the SCSI request instruction and the configuration completion information are mutually negotiated between the host and the USB device, and the format of the SCSI response message returned by the USB device to the host also needs to conform to the SCSI standard protocol.
步骤503、根据SCSI响应消息判断对USB设备是否配置成功。Step 503: Determine, according to the SCSI response message, whether the USB device is successfully configured.
在本发明的示例性实施例中，主机可以根据USB设备返回的SCSI响应消息判断是否对USB设备配置成功。在本发明的示例性实施例中，当SCSI响应消息为SCSI已配置响应消息时，表明USB设备的驱动加载和安装正常，主机判定对USB设备配置成功；当SCSI响应消息为SCSI未配置响应消息时，表明USB设备的驱动加载或安装不正常，主机判定对USB设备配置失败。In an exemplary embodiment of the present invention, the host may determine whether the USB device configuration is successful according to the SCSI response message returned by the USB device. In an exemplary embodiment of the present invention, when the SCSI response message is a SCSI configured response message, indicating that the driver loading and installation of the USB device is normal, the host determines that the USB device configuration is successful; when the SCSI response message is a SCSI unconfigured response message When it indicates that the driver of the USB device is loaded or not installed properly, the host determines that the configuration of the USB device has failed.
根据上述的分析可知，通过上述的步骤501～503，主机也可以向USB设备发送SCSI请求指令，然后主机根据接收到的SCSI响应消息判断对USB设备是否配置成功。当主机对USB设备配置失败时，主机可以控制USB设备可以将其工作模式从第一工作模式适配到第二工作模式，进而主机可以按照第二工作模式对应的第二配置方法对USB设备进行配置。According to the above analysis, the host can also send a SCSI request command to the USB device through the above steps 501-503, and then the host determines whether the USB device is successfully configured according to the received SCSI response message.

FIG. 6 is a schematic diagram of correspondence between an operating system of a host and an operating mode of a USB device according to an embodiment of the present invention. As shown in FIG. 6, when the operating system of the host is a Windows operating system, the USB device operates in the first working mode; when the operating system of the host is a non-Windows operating system, the USB device operates in the second working mode. In an exemplary embodiment of the present invention, when the USB device fails to configure the USB device, it indicates that the operating system used by the host is a non-Windows operating system, and therefore, the USB device needs to adapt its working mode from the first working mode to The second mode of operation, in this way, the working mode of the USB device can correspond to the non-Windows operating system used by the host, and the USB device can be used normally.
