This will permit you to see all the Drivers that are installed on PC Whenever you are attempting to [Install] & it appears to fail However, the Driver did get installed & remains and sometimes causes problems like you are having-Sometimes a [Unknown Device] gets installed that interferes with [Subsequent Installation]
Another problem If the [Mouse] and/or [Keyboard] was working fine & then all of a sudden one or both suddenly stops A recent [Automatic Windows Update] replaces Driver that for whatever reason is not compatible with a [Non MS Input Device]
Having [Device Manager] view [Non Present Devices] may let you see the correct/old Driver Not knowing all the details & not seeing problem in [Real Time] It is hard to give a [Detailed] Step by Step [Repair Process] that will fix this problem
The best I can do is give you the tool and some guidelines
These [Non Present Devices] usually are the Place Holder/Marker for the [Installed Devices] that are not connected or [Powered ON] Such as a Printer or Camera If they were not there Then the PnP would detect [New Hardware] every time you turned ON your Printer
So you do not want to eliminate ALL Just the [Problematic Ones] - [The Hard Part] in Problem Solving
