    How to make a uvc+vitual com  composite/compound device?

    sdz_2011_3494506

      Step by step procedure:

      1. Increase the interfaces 4 from 2 in config descriptor in UVC frameworks code and association interface would be 2 , one for each class

      2. Make sure the total length of descriptors are modified accordingly. I mean add CDC class descriptors

      3. Initialize all common blocks at one time and one place

      4. Setup call back incorporate both UVC+CDC

      5. Keep only one GPIO configuration

      6. Create  DMA channel for UART, another for UVC

       

      But when I finish  above procedure,I found  a device node named USB Composite Device with yellow exclamation mark  in window 7 Device manager in USB Host Side.It show as u1.jpg

      And  There is no FX3 UVC device in the Image Device Tree in window 7 Device manager(If I do nothing,There is a UVC device in the Image Device Tree)

       

      So,It is appreciated if there is a reference demo for such composite device or a more detailed guide.Another,Is there a newly host driver for this composite device?I just install CypressDriverInstaller_1.exe from the following link: http://www.cypress.com/documentation/software-and-drivers/usb-serial-software-development-kit

          sorry,I want to make a little correction.In the last 3rd line, Another,Is there a newly host driver for this composite device? 

          It would be:       Is it need a newly composite host driver for this composite device?

            Hello Andy,

             

            - Can you please share the descriptor file?

            - Also, please post the screenshot of the device manager that shows the error message on the composite device.

             

            Best regards,

            Srinath S

              Hi srnt:

                      please refer to the CyFxUSBCompositeSSConfigDscr structure  in the next  attach text(cyfxuvcdscr.c).

                      But there is something change showed in the attach picture in the last.

                      thanks!

                Hello Andy,

                 

                - Kindly, modify the Product ID in the device descriptor from 0x00F8 to 0x0008. This PID has been included in the Cypress provided INF file for CDC class driver. Test using this PID and update the findings.

                - Also, ensure that you have an active internet connection upon installing the device.

                 

                Best regards,

                Srinath S

                  Hi Srinath S:

                      I have a new doubt.For a uvc+vitual com composite device,the product ID in the device descriptor   match UVC PID or CDC PID?why?

                  I think that it is a composite device including UVC and CDC,windows host side have UVC driver and CDC driver, if the product ID in the device descriptor is one of the two,can Host side  enumerate the composite device including two interface?

                     Looking forward to your kind reply,thanks!

                    Hello Andy Zhou,

                     

                    The PID in the device descriptor is common to both the interfaces (CDC and UVC). Upon identification of two different interfaces, the Windows host loads the composite driver and enumerates the interfaces as separate devices. But, for the CDC class interface, it seems that your host PC did not find a suitable driver. Cypress provides a CDC class driver which is pushed to Windows Update. This driver can bound to a device with VID/PID 04B4/0008. This was the reason I asked you to modify the PID from 0x00F8 to 0x0008. Microsoft picks up this driver from the web and installs the same.

                     

                    Kindly, let me know if you were successfully able to bind the device with the modified PID.

                     

                    Best regards,

                    Srinath S

                      Hi Srinath S:

                           In my case ,with the modified PID,The windows host just bind the CDC,and then the windows host is "freeze" and any operation can not be do and can only reboot. I am confuse about that.

                           I refer the demo in the FX3 Video stream + UART comport  and change the PID and the config descriptor   for my board.Do you have some suggestion about that?

                         Thanks!

                        Hello,

                         

                        - Can you please post the firmware that you are using. Is it the same firmware as in the FX3 Video stream + UART comport or have you modified it?

                        - Please let me know if both the camera device (UVC class) and the COM port (CDC class) device enumerated properly.

                        - In case the enumeration is fine, let me know if you are able to stream image data onto the host PC and send/receive commands on the terminal using the COM port.

                         

                        Best regards,

                          Hello,

                           

                          Please refer to the below thread for an example project of UVC+virtual COM port.

                          Can EZ-USB FX3 enumerate serial devices and video and video devices at the same time?
