Like so many I can't get the drivers to work after the latest update. Windows 8.1 and when I plug in my Quest device manager only shows 'Other Devices - XRSP interace' and 'Portable Devices - MTP' there is no ADB Interface.If I turn off developer mode and connect then the Quest prompts to allow access and again all I see is XRSP and MTP. The XRSP has no driver installed. If I try and update the driver and point it at the latest Quest ADB driver it says it could not find the driver for the device.Basically no matter what I try I can't get an 'ADB Interface' to appear in device manager to try and manually select the driver.Any tips? Thanks.
