I had a problem yesterday that I ended up fixing on my own... decided to post and share my solution in case anyone else can benefit from it (problem stemmed from a botched uninstall.... power outage).
My rift sensor was being reported as "Not detected" within the Oculus App. Device manager was reporting that it was unable to find the driver. Uninstalling and reinstalling the Oculus Software had no effect. I found a folder located in C:\Users\<username>\AppData\Local\Temp\Oculus\ that contained "OculusRiftSensorDriver.msi", but running the installer had no effect on my problem. Here's what worked:
Unpacked the .MSI contents using 7zip and renamed the files as follows:
- OCULUSCAT > OCUSBVID.CAT
- OCULUSINF > OCULUSINF.INF
- OCUSBVID109 > OCUSBVID109.SYS
- OCUSBVID111 > OCUSBVID111.SYS
Right-clicked OCULUSINF.INF, clicked "Install", driver installed successfully, fixed.
