D200 not detected after Ulanzi Studio update

cocototo

Hello,

I am experiencing a serious issue with my Ulanzi D200 after a recent Ulanzi Studio update on Windows.

Background

• The D200 was working normally before the update.
• After updating Ulanzi Studio, the device became very slow.
• After another update / restart, it completely stopped working.
  
  

Current symptoms

• In Ulanzi Studio, the device status shows “Disconnected”
• When the D200 is connected to the PC:
  • Windows detects it as “USB Billboard”
  • If I remove the device, it disappears
  • If I reconnect it, it appears again as USB Billboard
    
    
• This indicates that USB connection is working, but Ulanzi Studio cannot communicate with the device
  
  

Important additional information

• I already tried uninstalling the latest Ulanzi Studio and reinstalling an older version that previously worked
• The problem still persists even with the older version
• This suggests the issue is not limited to the latest software version
• It may be caused by:
  • Firmware corruption during the update
  • Driver issue left behind after the update
  • Firmware and software no longer matching
    
    
  
  

What I have tried

• Reinstalling Ulanzi Studio (latest and older versions)
• Reconnecting the device multiple times
• Removing the USB device (“USB Billboard”) from Windows and reconnecting
• Direct USB connection (no hub)
  
  

Environment

• OS: Windows (64-bit)
• Device: Ulanzi D200
• Connection: USB (direct)
  
  

Questions

• Is there a way to force firmware recovery or re-flash firmware on the D200?
• Is there a manual driver installation for this device?
• Is this a known issue related to recent updates?
  
  

This is a screenshot when I connect D200 to PC, I can see a USB connection device.

At this point, the device is completely unusable.
Any official guidance would be greatly appreciated.

Thank you.
