Hello Veerendra,

I have attached the modified descriptor file and the uvc.c file for endpoint handling. I have created a DMA channel between USB and CPU and discarded the buffer as it is received. You can modify this to suit your application.

For the first time, the vendor interface comes under 'Unknown Devices' section and the device should be manually bound to CYUSB3 driver.

Best regards,

Srinath S

Hello Veerendra,

You cannot use the UVC class endpoint in the Control Center. But, you can define additional endpoints in a separate vendor interface and access them using the Control Center. This can be used to send custom vendor data to the FX3 from the PC host but not the UVC video data.

Hello Veerendra,

Please use the UVC class example as the base and add the vendor interface to the same since the UVC class specific requests would be handled in the example.

Hello Veerendra,

I have modified only the SuperSpeed related descriptors in the firmware. Kindly, use a USB3.0 cable and a USB3.0 port and check it.

Hello Veerendra,


Please let me know what you mean by 'modify the driver'. Do you mean to develop a driver or bind to a different driver?

Hello Veerendra,

I have attached the screenshot of the device manager when I use the IMG file from the debug folder. This would work only when the device is operating at SuperSpeed. So, kindly, use a USB3.0 cable and ensure the device is connected to USB3.0 port on the host PC.

Hello Veerendra,

Look for a device under the 'Other Devices' section with the VID/PID used in the firmware.

Hello Veerendra,

- In Windows 10, the device gets listed under the "Camera" devices. I have not modified the drivers. In fact, I am using the Microsoft provided drivers for the camera device.

- In order to use the Cypress Control Center to access the endpoints, the UVC class cannot be used. That is the reason I have implemented in Vendor class.

Hello Veerendra,

For camera device, the driver is available with Windows OS. For vendor class, forcefully bind the device to CYUSB3 driver that comes with the FX3 SDK.

Hello Veerendra,

Please follow the below steps.

1. Right click on the device and choose "Update Driver Software"

2. Choose "Browse my computer for driver software"

3. Choose "Let me pick from alist of device drivers on my computer"

4. Click on "Have Disk"

5. Navigate to C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\driver\bin\<OS_Version>\<OS_Architecture> and point to the CYUSB3.INF file

6. From the list of devices displayed, choose "Cypress FX3 Example 1" and click on OK.

Now, the device comes in the Cypress USB Control Center and you can define and use vendor commands to communicate with the device.

Best regards,

Hello Veeredra,

I have explained the steps that I perform to bind the device to driver. I am not sure what is going wrong at your end. In the last interaction that you have posted, the camera device is also not enumerating. Please re-check your firmware before loading into the device or use the firmware that I shared earlier.
