First 3 numbers of serial

100 is the 4k model (38402160)
102 is the BE model (2560

The 4k is likely what you have. Awesome detailed setup!

Was there any recent updates/install just before it stop recognizing the headset?

yea first 3 is 100 so a 4k model.

i havent updated anything big, did a java update and install NVIDIA GeForce Experience thats it,

Yeah that doesn’t sound like anything that should have caused an issue. But possible 1 of the 2 installs may have caused an issue.

Was Piplay version your using the same version when it was working before?

yes it was the same version. i will try and reinstall since my AVG just tryed to block piplay

i have seen that even your USB is not recognized in the connection page.
So first of all, you should make sure the USB connection is no problem.
after you incert USB cable, you will find a new HID compliant shown in device manager on PC.

Cable connect:

  1. HDMIcable directly inserted into HDMI port of computer independent graphics card
  2. USB cable is inserted directly into the USB port of the computer
    Helmet status:
    What color is the LED on the helmet after the connection?
    Blue: normal connection state
    Green:Please check the HDMI connection
    Red: Please check the USB and HDMI connections. Replace the USB port to re plug.
    Display card driver:
    please download latest driver:Official Drivers | NVIDIA
    When installing, anti-virus software / all kinds of security software must be turned off.:
    If the installation is not closed in time, please completely uninstall piplay and reinstall it.
    piplay download address:http://pisetup.pimaxvr.com/PiPlay_Setup_3.0.0.81.exe
