Another ongoing software problem . This windows 11 installation is defective . Device manager shows all sorts of "PCI device" without drivers .Of course windows 11 says absolutely nothing about what these devices are ....therefore impossible to fix problem ! ASUS PRIME Z690 A motherboard with i9-12900KF . The motherboard comes with driver disk . I have tried several times to load drivers butwindows 11 prevents this from happening . I have THUNDERBOLTEX 4 expansion card which does not work . Bluetooth does not work . The only thing that does work is Wifi . The bluetooth is part of the Wifi expa

Device Manager Un-Hiding Hidden Devices

When you connect a plug and play device, Windows Plug and Play manager detects it, finds and installs the driver. Device Manager lists the device with a solid icon.

The driver is only removed when you uninstall the device, not simply by disconnecting the device. When the device is disconnected, its driver is still installed. By default, Device Manager only displays connected devices. When you show hidden devices, note the Bluetooth icon you see is semi-transparent (not opaque). That indicates a "non-present" device. Sometimes also called a "ghost" device. The driver is still installed but the device is not currently detected (i.e. not connected).

Device can be disconnected when

• Device unplugged (e.g. removing a USB device)
• Turning a device OFF
• Disabling the device in BIOS (then windows won't detect it) or
• Device failure

So

• Check BIOS as suggested
• Check board connections
• Can b/t be turned off by a switch? or keyboard combination?

Also possible the b/t h/w failed

 

New Printer Not Showing in Devices & Printers (But Does Show in Device Manager)

Now I have no printers and Devices and Printers at all, not even a banner (but it still shows in Device Manager).



I have uninstalled all the new Brother printer driver & utilities programs (again) and rebooted (again). I also turned off MS XPS print services from Programs and Features, just in case. In Device Manager, I clicked ‘Show hidden devices’ and found
three instances of the old printer plus the old Prolific Parallel – USB adapter cable (now returned & refunded). All these were ghosted out but I uninstalled all of them anyway.

I checked ‘spooling’ in ‘Services’ and this is set to ‘Automatic’ (and is ‘Running’).
