CAPTIVATE-PGMR: An error occurs when connecting a custom board using CAPTIVATE-PGMR

Part Number: CAPTIVATE-PGMR
Other Parts Discussed in Thread: MSP430FR6045, , EVM430-FR6047

MSP430FR6045 Custom Board is being tested by connecting it to the USS program.

The PC and custom board were connected using CAPTIVATE-PGMR.
At some point while using it, when I run Connect in the USS program, the following error occurs.

"More that one HID device with the same VID/PID detected. Only one device may be conntected."

I did not connect any other devices other than the CAPTIVATE-PGMR board.


Disconnecting and then reconnecting or rebooting the PC does not solve the problem.

When connecting CAPTIVATE-PGMR to another PC and testing it, it was confirmed that it works normally.

Why does this problem occur? how can i solve it?

    Hi Jung,

    FYI - for the MSP430FR6045 USS family of MCUs, I don't believe the CAPTIVATE-PGMR's USB HID serial bridge will work.  It uses a communications protocol that is different than the USB HID serial bridge on the EVM430-FR6047 PCB and I believe it has a different VID/PID. You can use the CAPTIVATE-PGMR's eZ-FET programmer to program and debug the target, but you won't be able to communicate with the USS GUI.

    Regarding the error message you are seeing, if you close the USS GUI, disconnect all TI  EVM/Programmer, then launch the USS GUI, then connect the PGMR, do you still see the error message?  If so, try re-booting your PC.

    It has nothing to do with the MCU. The same message appears even if I select Connect with only the PC and Captivate connected without connecting the custom board.

    If I test in the same way on another PC, the message "USS show HID Bridge connected-- waiting for device" appears at the bottom of the USS GUI window.

    Also previously tested with the USS GUI - MSP430FR6045. Suddenly, at some point, this happens.
    As I said before, even after rebooting the PC, the problem persists.

    Hi Jung,

    This is really strange.  When you connect the Captivate programmer it should appear as a USB HID device.  Nothing special about that.  So this works on one PC, but not the other, correct?

    Do you know how to use the Windows PowerShell on the PC?

    If not, open a command line window and type <powershell>  without the <>, then type the command below.

    Get-PnpDevice -class HIDClass -PresentOnly | Where-Object{$_.PNPDeviceID -like 'HID\VID_2047*'} | ft InstanceId, Status, FriendlyName

    You should see something like this:

    Try on both your good working PC and the one that is giving you trouble.

    Let me know what you see.
