Windows 10: Can't add device in Device and Printers or Add bluetooth devices

I'm trying to connect some Bluetooth earbuds I have with an adapter I just bought. I know for a fact the adapter works it just doesnt work on my computer.


Any time I try clicking on either add device in Device and Printers tab or Add bluetooth device the box opens up for a split second and instantly closes.


The adapter is updated to its latest version. I've tried reinstalling several times and restarting PC. It just seems Windows is bugged.


Using Windows 10 Version 1909

windows 10 VERY slow when trying to open Devices & Printers?

Windows still has a MS-version of Bluetooth stack, and running BT services by default.
Didn't pay attention to the fact that you don't have a Bluetooth adapter.
Scratch my previous suggestion, and disable everything bluetooth-related in services. If that does not help - check network and sharing settings.
Devices and Printers manager also looks for network-attached multimedia devices (e.g. PCs with streaming service enabled) and network printers. If you by any chance changed network/homegroup settings on your additional PCs, then it could've affected the discovery speed on your computer. Still not sure how to fix it.

 

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

 

usb device not recognized (malfunction) - Printer

Hope somebody can help a non-techy here.
I have a canon IX4000 printer, and had been using it without problem. The next day (having touched nothing), I got a USB device not recognized warning, and that it has a malfunction (this is under Windows XP).

I've tried the following:
- deinstalling all USB drivers under device manager
- system restore to several days prior, when I knew the printer was working
- trying a different USB lead (tested the lead on another device, so know it works)
- plugged lead into every other available USB port on the computer (front and back).
- tried plugging it into another computer (comes up with the same malfunction warning)
- deinstalled the printer drivers, downloaded and reinstalled them.

Nothing I've tried works. I know the printer functions as I can start it up under service mode and print off test pages without problems, but my computer just won't have it. Could it be a hardware failure, and if not is there anything else I can try that isn't listed above?

Really grateful to anyone who can reply. *Smile
