Creality Otter / Creality Scan – "Scanner Undetected"



I’m hoping someone here can help me, but if not, at least anyone else with the same issue can pick up where I left off. A ticket has been opened with Creality, but I am not very confident in their ability to troubleshoot.

Problem Statement: Creality Scan shows “Scanner undetected” and will not recognize that the scanner is plugged in.

PC Specs

  • Motherboard: Asus ProArt Z790-Creator

  • CPU: Intel 14900K

  • GPU: RTX 3090

  • Memory: 64GB DDR5

  • OS: Windows 11 24H2

Constants:

  • The scanner shows up in Device Manager under ‘Cameras’ and uses Microsoft driver version 10.0.26100.2161

    • CR-Scan Otter Depth Camera
    • CR-Scan Otter IR Camera
    • CR-Scan Otter RGB Camera
  • The scanner has a pulsing green light and responds to the buttons when I touch them.

  • The scanner DOES work on a Mac Mini with Creality Scan 3.3.4 and I was able to update the firmware.

Attempted:

  • USB 3.2 ports (w/ and w/o addtional power cable)
  • USB C port with adapter
  • USB 3.0 port on a PCIe add-in card
  • Alternate high bandwidth USB C cable (Oculus Link)
  • Reattempted the above with supplemental power from the second USB cable
  • Restarted computer with scanner unplugged
  • Launched Creality Scan as admin
  • Tried various forms of launching app with scanner connected and without, restarting with it connected and not
  • Downgraded Creality Scan software from 3.3.4 to 3.2.46 and then to 3.2.24
  • Updated all motherboard and other drivers
  • Verified that ‘Let desktop apps access your camera’ is turned on in Windows Settings > Privacy > Camera
    • Camera does NOT show up in the apps that have requested camera access list
    • Verified that webcam privacy value is set to allow in ‘HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\CapabilityAccessManager\ConsentStore\webcam’
  • Disconnected all other cameras
  • Disabled Power Toys
  • Disabled Nvidia Broadcast
  • sfc /scannow found no integrity violation

Thanks in advance to anyone who might be able to assist.
