如何组合USB设备（没有HID+USBUART）？

我想你正在寻找如何在USB上创建复合设备，因为KBA将是有用的：
用PSoC 3、PSoC 4L或PSoC 5LP—KBA223 141实现USB复合设备



     以下为原文
  I think you are looking for how to create composite device on USB, for that this KBA will be useful:
Implementing USB Composite Device with PSoC 3, PSoC 4L, or PSoC 5LP - KBA223141

这个链接也可能是有用的：

  This link may also be useful:
PSoC5LP - Multiple USB devices on single USBFS component?

关于这些链接：我在找到问题之前就找到了。
这对我很有启发性：
我们有一个例子鼠标+ CDC UART我的目标非常相似（测试这个小项目：它的作品）
-我们有IAD配置说明（参见下面的配置）
-…
从我的角度来看，它不是固件问题，因为Windows可以安装自定义设备或USBUART司机：
-我只能安装一个
-秩序并不重要：定制或UBUTART
= & gt；但最后窗口没有在同一时间进入装置面板。
你有联系或例子INF文件安装结合USB设备？
罗宾。

  About these links: i found it before post my question.
It' was very instructive for me :
- we have an example mouse+cdc uart very similar to my goal (it tested this small project : it works)
- we have IAD config explanation (see below my config)

- ..
 
from my point of view it isn't firmware issue because windows can install driver for custom device or u***uart:
- i can install one only
- the order doesn't matter : custom or u***uart
=> but at the end windows cannot have both in the same time into the device panel.
 
Do you have link or example of inf file to install combined u*** device?

你好，罗宾，
我能理解的是，你有一个复合设备（HID+UBUART）和另外一个UBUART。
它类似于具有多个COM端口，这个链接可能是有用的：
作为多个COM端口的USB？



     以下为原文
  Hello Robin,
 
What I can understand is that you have one composite device (HID+USBUART) and one other USBUART.
Its similar to having Multiple COM port, this link may be useful:
Re: USB  as multiple COM ports?

安克斯，
谢谢你为我抽出时间。
因此，我的应用程序可以在CY8CKIT-059上工作，我将分享我的项目并试图解释预期的行为。
CyPress KiPro（绿色）被检测为“双”设备：UARTCOM和KitProg
但是我的USB设备，我只能同时看到一台设备，而不是像吉普格一样。
事实上，我期待Windows要求我安装2个设备驱动程序后，将USB插头插入USB连接器（橙色侧）…
但只要求一个！！
奇怪的事情是我可以安装驱动程序
USB UART：驱动程序（*.INF）进入文件夹生成的源程序
-我的应用程序：我不能共享它（但是如果我安装它，USB UART（COM30）消失。）
Windows只能显示我的USB设备中的一个。然而，Windows有可能显示2个设备用于同一个USB连接器：KitProg就是这样。
最好的问候，
罗宾。

  anks,
Thank you to take time for me.
 
So my application can works on CY8CKIT-059, i will share my project and try to explain the expected behavior.

The Cypress KitProg (green) is detected like "double" devices : UartCom AND KitProg
But my u*** device, i can only see one device at the same time not both like kitProg

 
In fact i'm expecting that Windows ask me to install 2 devices drivers after plug the USB into the u*** connector (orange side)...
But only one is requested!!
The strange things is i can install driver for
- USB UART : the driver (*.inf) is into the folder Generated source
- MY APPLICATION : i cannot share it (but if i install it, the USB UART (COM30) disappears.)
=> Windows can show only one of my USB device. however it is possible that windows shows 2 devices for the same USB connector : it's the case with KitProg.
 
best regards,
Robin.

你好，罗宾，
谢谢你的解释。
请通过HIMA检查这个论坛线程交互04，这将是有益的：
用两个VCP和一个“自定义”接口创建USB组合设备
对于使用IADS的设备，该设备用INF文件中的接口的PID VID和MI（多接口号）组合来识别。因此，相应的INF文件必须被改变，包括界面的英里数。对于我们的示例项目，供应商特定的接口有mi_00和CDC类有mi_01。因此，我们将改变INF文件u***fs_1_cdc INF包括CDC类接口MI：从描述：% % = driverinstall，USB vid_04b4 &；pid_8051：% % = driverinstall描述，USB vid_04b4 &；pid_8051 &；mi_01
同样，在cyu***.inf将被修改为包括供应商特定的接口VID和PID和MI：：% vid_xxxx &；pid_xxxx。DeviceDesc % =适用于CYUSB，USB vid_xxxx &；pid_xxxx：% vid_04b4 &；pid_8051。DeviceDesc % =适用于CYUSB，USB vid_04b4 &；pid_8051 & amp；mi_00
改变的INF文件可以用来指向一个设备驱动程序。如果你使用了错误的INF文件为设备，如用mi_00 INF文件mi_01接口。它会把错误说INF文件不包含您的设备信息

  Hello Robin,
 
Thanks for the explaination.
Please check this Forum thread interaction#04 by HIMA, it will be helpful:
Create an USB composite device with two VCP and one 'custom' interface
 
For a device that uses the iADs, the device is recognized with the PID-VID-and-MI (multiple interface number) combination of the interface in the inf file. Thus, the appropriate inf files have to be altered to include the MI number of the interface. For our example project, the vendor specific interface has MI_00 and the CDC class has MI_01. Thus, we will alter the inf file USBFS_1_CDC .inf to include the MI of the CDC class interface: From: %DESCRIPTION%=DriverInstall, USBVID_04B4&PID_8051 To: %DESCRIPTION%=DriverInstall, USBVID_04B4&PID_8051&MI_01
  
Similarly, the CyUSB.inf will be altered to include the VID and PID and MI of the vendor specific interface: From: %VID_XXXX&PID_XXXX.DeviceDesc%=CyU***, USBVID_XXXX&PID_XXXX To: %VID_04b4&PID_8051.DeviceDesc%=CyU***, USBVID_04b4&PID_8051&MI_00
  
The altered inf files can be used to point to the driver for a device. In case if you use the wrong inf file for a device, like using the MI_00 inf file for MI_01 interface. It will throw up the error saying that the inf file does not contain the information for your device

安克斯，
Mixxx帮了我一点忙。
Windows可以指示2个驱动程序，但Windows只能安装一个。
它似乎接近解决我的问题，但目前情况并非如此。
罗宾。

  anks,
MI_XX helps me a little bit.
 
Windows can indicate 2 drivers but windows can only install one.


it's seems close to fix my issue but currently it's not the case.
