Windows 10: Uninstalled bluetooth from device manager, unable to install again

My Bluetooth adapter was hidden and was not connecting to the hardware. So I decided to uninstall the Qualcomm Atheros driver. However, when I downloaded my driver again from Lenovo support, it is still not working. In turn, I am also getting an 'Unknown USB Device( Device Descriptor Request Failed)" on my device manager. I tried various fixes from online articles but nothing seems to work.


The System SKU is: LENOVO_MT_80FG_BU_idea_FM_Lenovo Z70-80


Any help is appreciated. Thank you.

Uninstalled Bluetooth Devices Automatically Install


The issue is; when I pair a device with my computer using Bluetooth I am no longer able to unpair, or even uninstall the device, as if i do, somehow windows will just automatically reinstall it even if it's not connected. This means that if i connect the device to something other than my computer, I can no longer re-pair it with my computer as it thinks that the device is still paired.

When I pair the device from the Bluetooth section of control panel, the device will disappear from the control panel Bluetooth menu, and the only way to see that the device is connected is by looking in device manager.
Here is an image I have found of what the Bluetooth section of the control panel should look like with paired devices:



Now here is what mine looks like even though I have a number of devices connected:




Here's what I've Tried
I have removed, and completely uninstalled all Bluetooth devices from the PC using device manager (even the hidden devices), and also uninstalled all Bluetooth applications from the control panel.
After doing the previous steps, I reconnect the Bluetooth dongle (ASUS BT-400) and install the driver I downloaded from the Asus website. As soon as the driver for the device install, all of the previously paired (since time began) devices will install and windows will think they air all paired (again I can see this though the device manager).

I had this issue when I was on windows 8.1 and I have it again now. I did a clean install of windows 10, and the issue still persists even though I have tried two different Bluetooth adapters (to make sure one wan't faulty). How is Windows storing these devices to re-install even though they're not connected?

 

Bluetooth services and device manager

Hi Tina,

Having an incompatible driver causes functionality issues like what you are experiencing right now with your Bluetooth. To resolve such issue, we suggest that you uninstall and reinstall your Bluetooth drivers manually instead of letting Windows search for
an updated driver automatically. Here are the steps to do that:

• Visit your device manufacturer’s website to download the latest driver.
  
• Right-click on the Start button, then select Device Manager.
• Select Bluetooth, then the Bluetooth driver
  name.
• Right-click on driver and then select Uninstall device >Delete the driver software for this device check box >
  Uninstall.
• After uninstalling, right-click the driver that's having the issue, select
  Update driver > Browse my computer for driver software.
• Select Browse > look for the drivers you've just downloaded >
  OK.
• Select Next > follow the steps to install the driver >
  Close.
• Restart your computer.
