I get the error "The INF file you selected does not support this method of installation". I found one topic on the forum but the solution didnt make sense in this context. I asked me to install a sensor driver that has nothing to do with the Oculus Go.
To get this working on Windows 7, go to device manager. You should see "VR headset" with an exclamation symbol next to it, signifying no driver. Right click, select "Update Driver Software", choose "Browse" and select the folder containing the extracted drivers. You'll see "Oculus ADB Interface" once complete.
I Tried DanR advice , on windows 7 (64 Bit), still did not work for me, But this did, Device Manager, Update driver Software, "Let me Pick from List", Choose "non-Plug and Play Drivers" then have disk and navigate to go to "android_winusb.inf" then it installed for me and my Oculus GO was visible. (BTW i had to turn off Development mode on my phone for the go , for some reason)
