Troubles with Bluetooth after latest Intel driver updates RRS feed

  • Question

  • Hello guys,

    I know it is not a place to ask about troubles with drivers, but:

    a) I am fairly experienced user and Java dev
    b) I had perfect OS (Windows 10 Enteprise 1909 64bit, build 18363.752) state untill I upgraded Bluetooth and Wifi drivers using Intel(R) Driver and Support Assistant

    Since that upgrade my Bluetooth seems to be dead for Windows (on/off switch disappeared, Bluetooth devices went to hidden in Device Manager (light blue), I do not see any Bluetooth Support service in services.msc). Generally: it looks like something (drivers :-)) is broken in my PC.

    I reported issue to Intel here: https://forums.intel.com/s/question/0D50P00004dmXofSAE/bluetooth-not-working-since-wireless-bluetooth-drivers-updated-to-latest-version-ac-7265-latest-windows-10-enterprise-1909-64-bit?language=en_US, but we are not really progressing.

    I have one unknown device currently in the system:
    C:\Users\myuser> pnputil /enum-devices /problem /ids /relations
    Microsoft PnP Utility

    Instance ID:                USB\VID_0000&PID_0002\5&16bdd27b&0&9
    Device Description:         Nieznane urządzenie USB (żądanie deskryptora urządzenia nie powiodło się)
    Class Name:                 USB
    Class GUID:                 {36fc9e60-c465-11cf-8056-444553540000}
    Manufacturer Name:          (Standardowy kontroler hosta USB)
    Status:                     Problem
    Problem Code:               43 (0x2B) [CM_PROB_FAILED_POST_START]
    Driver Name:                usb.inf
    Hardware IDs:               USB\DEVICE_DESCRIPTOR_FAILURE
    Compatible IDs:             USB\DEVICE_DESCRIPTOR_FAILURE
    Parent:                     USB\ROOT_HUB30\4&cb12d54&0&0

    Parent device is running MS driver and it is "Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)" / MS driver version 10.0.18362.693 dated 2020-02-20 (quite recent).

    However I would bet I did not have any "problematic" devices in the OS before - untill I made upgrade to latest Wifi & Bluetooth drivers. Meanwhile I have installed 2020-03 security fix I think, but I was without working Bluetooth already.

    Could you kindly assist masters? :-) Sometimes it is really easy to answer for person who know details. My apology but I blame Intel drivers or Windows a bit. I do not know what failed from user perspective, because I am running this PC successfully for a few years (upgrading system when upgrades are available). Never had to throw bad words... I need Bluetooth these days as we all use teleconferencing now (plus it annoys me a lot I can not solve issue myself :-))

    BTW. My notebook does not have physical radio (Bluetooth/Wi-Fi) switch/toggle. I am not able to bring Bluetooth back to live again and I really tried many things in the OS. I do not have any experience to devcon, but I am thinking of trying to use it :-|

    Many thanks in advance for your assistance!

    Kind regards
    Pawel

  • My notebook does not have physical radio (Bluetooth/Wi-Fi) switch/toggle. 

    Which notebook? Have you asked their support too? They know their stuff better.

    The failing USB device likely is your BT controller. (Yes, AC-7265 is PCIe, but its bluetooth sits on USB)

    While waiting for more helpful suggestions, try to disable & enable it in Device Manager few times.

    Until you get a reply from the notebook support, please abstain from installing generic Intel drivers. This wireless stuff is very complicated, some OEM variants require specific quirks. Generic Intel driver can be not suitable.

  • Hi Pawel :-)

    Thank you for your prompt response. It is Asus ROG G752VT as stated in Intel ticket (there is a hardware description from Intel Support Assistant tool attached to my main post on Intel forum).

    I did uninstall Intel(R) Dual Band Wireless AC-7265 adapter and rescanning in Device Manager (without OS reboot) brings back device immediately with Microsoft driver 19.51.8.3 dated 2017-10-17. This Microsoft driver can not be uninstalled and is brought by the system I belive (Microsoft Windows digital signature).

    Generally I uninstalled Wifi device several times deleting drivers that were brought by Intel updates. I came "down" to Microsoft AC-7265 driver that can NOT be uninstalled (no option to remove driver files in Device Manager).

    I suspect that I did not have this Microsoft device before (I think that its naming was a bit different): "Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)". I suspect that USB controller utilized Intel, not Microsoft driver (it is parent device to the unknown device I have shown in the ticket). I do not know how to replace, but I really doubt whether it utilized Microsoft driver (I can not recall "- 1.0 (Microsoft)" suffix in any device in Device Manager).

    Obviously Intel Driver Assistant / Intel drivers broken my Bluetooth, but it should not be so complicated to move forward and revert back? :-|

    Currently I do not have Intel(R) Wireless Bluetooth (hidden/light blue) device, because I removed it in Device Manager. It does not come back on rescanning.

    I have opened ticket in Asus support as well. I am afraid that they may even do not know what pnputil in Windows is, but we let's see.

    I would appreciate more suggestions as reinstalling Windows is not really an option for me :-|

    Kind regards
    Pawel

  • Pawel,

    You are my hero. I have disabled Unknown device and re-enabled it without rebooting and....

    it has been identified as "Intel(R) Wireless Bluetooth(R)" and is solid blue now. Bluetooth switch in Windows is back.

    Muchas Gracias, you are my hero!!!!! So simple solution I would never say it could work.

    Do you have any idea why it did work (disable/enable) and why Windows could not recover itself? (PC has been rebooted multiple times)

    I would highly appreciate speculations as I completely do not understand what has happened and why your solution worked.

    Bluetooth is back. Yupi!

    Kind regards
    Pawel

  • Glad it worked for you.

    For other drivers (AC-7265, USB 3.0) - please consult with Asus.

    I would highly appreciate speculations as I completely do not understand what has happened and why your solution worked.

    Sorry, speculations are not my area of competence :) But often a simple measure helps with complicated issues ;)
