    Bluetooth not working since last Windows updates


    Split from this thread.​


    Same problem. I have a new-ish Dell Inspiron 5493 with Win 10 Home. Microsoft just updated the OS this evening and now my Bluetooth mouse is gone.


    So I go to Bluetooth settings and where there's normally a slider switch icon to turn Bluetooth off/on, there is none now. Just the add device "+" sign. If I go through the process to add a device Windows immediately says it can't connect with no time delay or anything.


    So I run the Bluetooth troubleshooter and it reports "Device does not have Bluetooth. Try using an external adapter" Before the update the computer certainly had a Bluetooth adapter.


    So I go to DeviceManager > View > Show Hidden and see various Bluetooth drivers. Bluetooth Device, Enumerator, LE Enumerator, two Phone devices ? and Qualcomm QCA9377 Bluetooth. If I click to update their drivers Win says they're already present and up to date. Yet Bluetooth settings apparently cannot see the drivers. So I uninstalled the Qualcomm thinking I could reinstall it. At that point all Bluetooth drivers disappeared.


    The only squirrely bit is that it's showing an "Unknown USB Device Device descriptor request failed. I'm reluctant to start tampering with that.


    So finally I try doing the system restore back to before the update was installed. That fails of course as I've *never* had restore work for me since Win 10 came out. It always complains it cannot access some file which it helpfully does *NOT* name for me so I could look into the problem. Oh, and this is with my antivirus software disabled, not that this ever helps restore anyhow.


    Any suggestions? Either to restore Bluetooth or to back out the Windows update?

    :)

    Bluetooth in windows 10

    My computer specs are as listed in the profile. I think all of you guys are correct. I don't have built-in Bluetooth in mobo.

    I contacted skull candy headphones and thy have told me if I do not have built-in Bluetooth, I would need a dongle which supports at least a2dp. I do not know what the heck that means. I have a feeling I would need more than a cheap dongle.

    Anyone suggest some a2dp adapters. I searched but don't know what a2dp is so couldn't make a decision

    Bluetooth in windows 10

    USB-BT211 Mini Bluetooth Dongle | Networking | ASUS Global

    • Support A2DP for Wireless Stereo Music Playback
    Edit: This is a dongle with old BT version I see now, but I'm sure you can find a Asus BT4.0 version.

    Edit2:

    @aasim1111 I have this one, it doesn't show that it supports A2DP in the specs but I think it'll work, otherwise send a mail to Asus and ask.
