    BTHUSB warning event ID 34


    "The local adapter does not support an important Low Energy controller state to support peripheral mode..."

    This pops up as a warning in Event Viewer every time the 3148 laptop is booted or awakened from sleep.

    As a test, "Allow this device to turn off this device to save power" has been disabled where available under Device Manager performance tabs for Bluetooth entries - to no effect.


    BT works. and it's understood that the warning is benign. But can it be eliminated?

    Hi there. Did this happen after the recent Windows Update?

    Is this a Dell 3148 laptop? If so, this one? http://downloads.dell.com/Manuals/al...uide_en-us.pdf

    Is the latest driver installed for the adapter?

    BTW, you show a tower in your system specs. There is now an option in your Settings Control panel to list a 2nd system.

    Yes, 2nd system is now listed in specs here.
    Is the latest driver installed for the adapter?
    Apparently. In Device Manager, a right-click|UPDATE DRIVER on any BlueTooth item returns "best driver already installed."

    Dell does have several 1708 BT drivers. The latest, recommended by their tech, was tested. Not only didn't it alter this issue, but audio quality was decidedly degraded. It is a Widcomm package that provides a BT control panel.

    Thanks for your input.

    You're welcome. Don't know what the best solution for you is. Have you created any restore points or recovery disks?

    This was a fresh install, and I'll wager that the warning has always existed. DISM and SFC are good, and there are no rollback options available for BT devices. Not an error and not a major concern. Thanks for the suggestions.

    Borgus, FWIW, I akso have a Dell laptop. New computer, bought it early last month. The laptop came with 1607 and is now upgraded to 1703 15063.540. I seen that Warning from day 1, and only after rebooting or cold start. I know it has to do with BT and I dont let it bother me. I dont use BT and haven't tested it.

    Good approach. Warning shows up on another Dell as well - one using a WiFi adapter that is different from the 3148's.
