    Issue with HX2VL-CY4608 development kit as USB hub

    user_14997725

      Hi,

       

      We are using USB 2.0 (embedded) host and connecting USB hub to it to stream video stream from 2 cameras.

       

      1. When we use our USB 2.0 (embedded) host  connected to quantum zero qz-hb03 hub and connect 2 FS (full speed) cameras to this, we can stream the video data - till maximum resolution VGA @ 30FPS.

      2. Same thing when we replace with HX2VL-CY4608/CY4608M developer kit and 2 FS (full speed) cameras (USB 2.0 (embedded) host  connected -> Cypress hub -> 2 FS cameras), we are limited to very less resolution (QCIF (176x144) @ 30FPS).

       

      As our final product is based on cypress hub - wanted to know

      a. Is there any setting that needs to be done with Cypress hub (any configuration etc)?

      b. Is there any way we can find out the difference between Quantam hub (which is working) and Cypress hub?

      c. I see the Cypress kit uses the EEPROM for configuration. Is there any specific tool that can be used to read the content and modify the content (if needed).

      d. Is there any way we can find out the hubs are using STT (Single Transaction Translator) or MTT (Multi Transaction Translator) - as this may be affecting the functionality and performance.

       

      Any other combination/ experiment can help us to debug this issue further and any pointers on this would help us to finalize the BOM and POC.

       

      With best regards,

      Phani.

          Hi Phani,

           

          CY4608 uses Single-TT Hub part and CY4608M uses Multi-TT Hub part as the name (M) suggests.

          Yes, Cypress HX2VL uses EEPROM and can be configured using Blaster Utility which is available at: HX2VL  in getting started tab.

          Please bind the Cypress Hub to vendor driver to update the EEPROM, and the vendor driver is attached with this thread.

           

          Regards,
          Anil

            Hi Anil,

             

            Thanks for your email. Downloaded the blaster utility and the driver you

            provided. When I tried to update the driver (binding cypress hub to vendor

            driver) - windows is saying - driver is not verified and still shows as

            warning symbol in device manager. Here is the screen shot of the issue. Any

            suggestion for me on this?

             

             

             

            With best regards,

            Phani.

              Hi Anil,

               

              Also here are other details (if it helps you in isolating the problem).

              Basically the red LED glows for a short duration and again turns off.

               

              1. We are using CY4608M HX2VL 4-Port MTT development kit (this detail is on

              the box we received)

              2. JP1 jumpers are all OPEN

              3. J5 is closed

              4. SW1 - dip switch in towards inside the board (other possibility is we

              can move it to other position, which would be towards the end of PCB).

               

              Not sure, above 2 - 3- 4 points affect the custom driver installation.

               

              I assume if the above installation successful, then we can see the device

              in Blaster utility right?

               

              With best regards,

              Phani.

                Hi Phani,

                 

                Please select the checkbox to 'Always trust the software from Cypress Semiconductors'.

                Please uninstall the driver and install again and try with other ports as well.

                2,3,4 points above will affect driver installation.

                Your assumption is right that after installation, you can able to see the device in Blaster Utility.

                 

                Regards,

                  Hi Anil,

                   

                  I do not get that "always trust... " option. After some googling, reading

                  etc, I figured out that - basically win 10 (64 bit) does not allow unsigned

                  drivers... finally I modified the windows option to support unsigned

                  drivers (doing some setting change in startup etc.) and now I can see the

                  Cypress driver being recognized when the CY4608M (hub) is connected to PC.

                  Below is the image of how it looks like.

                   

                  1. Still I am not able to see the device in Blaster. I can see the device

                  getting loaded when the hub is connected - but when I run Blaster - still

                  it does not show the device.

                  2. (a) JP1 jumpers are all OPEN (b) J5 is closed (c)  SW1 - dip switch :

                  You need to tell me what should be the correct setup of these jumpers/

                  switch. If you tell me "2,3,4 points above will affect driver installation"

                  I will be as clueless as before (as there is no documentation). For

                  Blaster to recognize the device - any of these settings to be set in any

                  particular order?

                  3. Is there any write up on the values shown in blaster? How do I

                  understand the data from device (or read .iic file with HxD or similar hex

                  reader)? Basically I want to understand these values and program different

                  combinations and see if it helps in using the Cypress hub for our product.

                   

                   

                   

                   

                  With best regards,

                  Phani.
