    Hi,
    

    My new EV-SC594-SOM board is not recognized by my PC via USB-C, showing a "USB Device Not Recognized" error. Both RX and TX LEDs remain constantly on when powered via USB-C or through the carrier board.
    

    The boot mode is set to position 1 (default). On power-on or reset, the LEDs blink once, followed by three blinks, suggesting the default program is running correctly. I’ve tried different USB-C cables and PC ports, but the issue persists.
    

    Currently running Windows 11. The board appears in Device Manager as an unknown device. No other USB devices are connected, and I’ve rebooted the PC.
    

    Any suggestions on what might be causing this or next steps to troubleshoot? Could it be a driver, hardware, or configuration issue?
    

    Best regards!

      Hi ,

      Could you please let us know whether you have connected cable in the USB hub port. please confirm once.

      If so, try connecting the USB cable in USB port of PC and check the status.

      Also, Can you check again by re-installing the driver manually? The drivers are found in the "Emu_Drivers" directory:
      <installation drive>:\Analog Devices\CrossCore Embedded Studio 2.x.x\Setup\Emu_Drivers

      Please refer "Installing drivers manually" in Emulator and Evaluation Hardware Troubleshooting Guide 
      http://www.analog.com/media/en/technical-documentation/application-notes/EE356.pdf

      And, we recommend you to refer "Debug Interface" and "Board Power" chapters in the below linked user manual.
      https://www.analog.com/media/en/technical-documentation/user-guides/ev-sc594-som_manual.pdf

      If still the board not detected in device manager, please share us the below details to assist further.

      1.Have you used this evaluation board before or this is the first time you are using it? 
      2.Provide us with a screenshot showing the ICE Test results.
      3.Which emulator that you are using? Do you have any other emulators of the same type, which operates correctly with the same target board and PC?
      4.Do you have access to another PC? If you do, please let us know if the board detected correctly without any issues?
      5.Let us know that you have purchased the emulator directly from Analog Devices or from distributor.

      Regards,
      Santhakumari.V

        Hi, thanks for the answer.
        

        Apparently, the FT232R ic is damaged. We replace it and the board started to appear in windows, but we do not know why the chip died.
        

        

        Thanks for the support.
        

        

        Best regards.
