Intel 7260 AC - BT not working on NUC D54250WYKH

Hello,

I've installed Win8.1 x64 a couple of hours ago, and with it all the latest drivers. Bluetooth device in Device Manager was there for a while, but now it's gone.

 

Instead, I see "Unknown USB Device" with error code 43. I've searched high and low for solution to this problems, found that other people had this issue too, but couldn't find the remedy that would work permanently. Once again, I have all the latest drivers installed for both NUC and 7260, but the issue persist, nevertheless.

Any ideas?

Thanks,

 

I.P.

Hello Gotrunx,

The error code 43 in Device Manager indicates that Windows stopped the device because the driver reported an unspecified issue with it. It can be caused by hardware, driver, or other Windows components.

Here are some initial actions that can help in this situation:

1. Do a clean install of the Bluetooth driver from Intel using the following actions:

- Reboot the computer.

- Go to Windows control panel, under programs and uninstall "Intel® PROSet/Wireless Software for Bluetooth Technology".

This can also be done in Windows Device Manager, Bluetooth, by right-clicking on the Intel Wireless Bluetooth, select Uninstall, and mark the option to "Delete the driver software for this device".

- Update the driver with https://downloadcenter.intel.com/download/24681/Intel-PROSet-Wireless-Software-for-Bluetooth-technol... Intel® PROSet/Wireless Software for Bluetooth® technology for Windows 8.1* 64-bit (WP) version 17.1.1411.01.

2. Check with Microsoft and confirm you are using applicable critical updates and Service Packs.

3. Make sure your NUC D54250WYKH is using the most recent Driver Bundle (currently March 2015), and BIOS update from https://downloadcenter.intel.com/product/76977/Intel-NUC-Kit-D54250WYK Intel Download Center.

4. Confirm that the wireless adapter is properly installed in the NUC, as instructed in thehttp://downloadmirror.intel.com/23090/eng/D54250WYKH_D34010WYKH_UserGuide01.pdf Intel® NUC Kit D54250WYKH User Guide, page 6.

Thanks for your help, but I've tried and check all of that at least a couple of times. I'm getting pretty annoyed here. I bought adapter because of Intel's official recommendation, and it seems like it's not compatible with my NUC. There is a bunch of people with the same problem, and I'm aware that this is insignificant amount of users for Intel but we all went to too much trouble to get things working even though they should function almost seamlessly. To my surprise, the adapter is still listed as fully supported on Intel website, even though people have been complaining about this for months now:

I just want an official answer: Is Intel wrong on this one, and do we simply need to give up and buy another adapter or do we still wait indefinitely for driver update?

You may also perform the following actions:

- Shutdown the NUC and unplug it from the power source for a couple of minutes, then power it back. This has helped other users with this issue.

- Update the NUC BIOS. The recent BIOS versions (currently 0037) have fixes for this condition.
