I plugged-in my Vive and it works perfectly fine on win 10 so I don’t think it is an usb issue (latest usb & chipset driver already installed).
Firmware: Latest (V18.104.22.168)
windows 10 version 1809
Nvidia driver version 419.35
-Re-install new firmware using dfu tool
-Delete lighthouse folder “\AppData\Local\Pimax\runtime\config\lighthouse”
22.214.171.124_beta : Not tracked
126.96.36.199_R193 : Not tracked
188.8.131.52 : Not tracked
181_95 : Device not detected (Latest firmware not working on this version?)
-Positioning tracking works when I turn lighthouse tracking off.
-Switched back to win 7 again and it works.
-Switch usb 2.0/3.0 ports
*Update: I reverted firmware to .181 and now it works with old pitool version 1.95 …
*Update no.2: When I upgrade to latest firmware .193 (and pitool .109_R193 / .111_beta), It tracks (orange message gone) but position of all my devices are wrong (basestation on my face, controller under my feet…). Then I restart PiServiceLauncher and it is back to “Not Tracked” (happened twice in my two attempts to upgrade).
*Update no.3: When I wave my controller in front of my HMD, I can see “fragment” of Pimax Home environment blinking in the grey screen… (status remains “not tracked” )
