怎么与USB设备通信

我和blackhorse01有类似的问题，并且没有运气就尝试了changmeikuan的建议。
我正在尝试将USB接口连接到自定义板并具有Vid和Pid。
我甚至有VB6程序，它将通过USB连接到电路板，发送命令和接收数据。
我尝试使用导入库函数，它在头文件中给出了一个错误“APWINUSB_API是一个未知数据类型。它在头文件中引用的整行是”APWINUSB_API BOOLEAN bClos​​eDriver（void）;“。有谁能告诉我
我做错了什么？谢谢！

  I have a similar problem to blackhorse01 and have tried the suggestions of changmeikuan with no luck. I am trying to USB interface to a custom board and have the Vid and Pid. I even have the VB6 program that will interface via USB to the board, send commands and receive data back.
I tried using the Import Library function which gave me an error in the header file of "APWINUSB_API is an unknown data type. The entire line it refers to in the header file is "APWINUSB_API BOOLEAN bCloseDriver(void);".
Can anyone tell me what I'm doing wrong?
Thanks!

I / O库（VISA）和VEE仪器管理器只能与符合USBTMC（USB测试和测量类）协议的USB设备通信。
您的USB鼠标，打印机和其他USB设备没有出现在Connection Expert和VEE Instrument Manager中是有原因的。在您的情况下，正确的方向是导入和使用DLL功能。
但是，定义文件不得包含任何用户定义的数据类型，宏等。必须使用基本数据类型定义返回和参数数据类型。
通常，您必须将“普通”头文件稍微修改为VEE定义文件。在VEE帮助中搜索“定义文件”以获取更多信息。



     以下为原文

  I/O Libraries (VISA) and VEE Instrument Manager will only be able to communicate with USB devices conforming to the USBTMC (USB Test&Measurement Class) protocol. There is a reason your USB mouse, printer and other USB devices doesnt show up in Connection Expert and VEE Instrument Manager.

In your case the right direction is to import and use the DLL functions. However, the defintion file must not contain any user-defined datatypes, macros etc. Return and parameter data types must be defined using fundamental data types. Usually you have to modify a 'normal' header file slightly into a VEE definition file.
Search for 'defintion file' in VEE help for more information.

如果您找不到相关的帮助文件页面。
它是讲述我>用户定义的函数>编译函数>定义文件。
尝试搜索头文件（.h），如果APWINUSB_API有任何定义，则将其替换为实际数据类型，例如：
Int64等



     以下为原文

  In case if you couldn't locate the relevant help file page. It is Tell Me About > User-Defined Functions > Compiled Functions > The Definition Files.
Try to search the header file (.h), if there is any definition for APWINUSB_API, then replace it with the actual data type e.g. Int64 or etc.

我的USB设备不是USBTMC，所以我需要使用.NET参考来发送命令并从USB设备读取响应。
有没有人有一个样本Vee程序，我可以学习使用DLL和从USB设备发送/读取。
谢谢

  My USB device is not a USBTMC, so I need to use .NET reference to send a command and read a response from USB device. Does anyone have a sample Vee program that I can learn to use DLL and send/read from USB device.
Thanks

嗨Klinn，你能分享一下你的vee u***界面吗？
截图不是很清楚。
谢谢和问候，Leomag

  Hi Klinn,

Could you share your vee u*** interface? The screenshot is not very clear.

Thanks and regards,
Leomag

我发现这个设备E5813A网络化5端口USB集线器。
我们可以将非USBTCM设备连接到此USB集线器，我可以使用Vee程序控制我们的设备，而无需通过dotNet或某种东西。
谢谢



     以下为原文

  I found this device E5813A Networked 5-Port USB Hub. Can we connect our non USBTCM device to this USB Hub and I can use Vee program to control our device without go thru dotNet or some kind of stuffs. THANKS

Blackhorse01,5端口USB设备将用于从计算机路由对非USBTCM设备的访问，但我相信您仍需要一个驱动程序和头文件，以便Vee程序与设备通信。
设备制造商可能能够为您提供帮助。



     以下为原文

  Blackhorse01,
The 5 port USB device will work to route access to the non-USBTCM device from the computer but I believe you will still need a driver and header file for the Vee program to talk to the device. The device manufacturer may be able to help you with this.
