Hello,

Please use the Cypress USB Control Center application to issue the vendor commands. You can refer to the CyControlCenter.pdf document (see attachment) for guidance on usage of the tool.

Hello,

- Have you issued the vendor commands from the host application and have they been successful?

- If yes, please send the captures from the I2C lines.

Best regards,
