Bluetooth not working Windows 10 (Error code 43) Help!!

I have exactly the same problem.

How can I solve it?

Well, actually my problem is a bit wider.

First I could not connect my wireless mouse through USB dongle to the USB 3 port. I got a message that USB device (i.e. mouse) is not recognozed - (Error code 43).

After that I tried to plug in my phone through the USB dongle to the USB 3 port. Again, phone was not recognized.

At the same time, external harddrive connected through the same mode is recognized.

Yesterday, I tried a solution outlined here (https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/Fix-for-Unknown-USB-Device-Device-Descriptor-Request-Failed/td-p/5973953). And it worked for several hours. However, after another computer restart, the problem reappeared.

The problem is with some software. But Dell Support cannot help me figure out which software is it.

Hopefully, you've made it work. I found this to work for me:

While all my drivers and everything else was up-to-date, my device manager was still showing error code 43. I downloaded this from the Dell support page (not sure if this is universal, but visit your support page to customize to your device). 

After installing it, it repaired all my drivers & files, and it is now working. 

Does the OP still have this problem? My problem is EXACTLY the same. However, I didn't SIMPLY uninstall the driver and reboot. It took me a long time to find that solution. This time, it was the first thing that I tried and I was really surprised that it didn't work.

I ran out of time on editing my message just before I finished. I wanted to add these details.

I have a Dell Precision 5530. The Bluetooth adapter is a Qualcomm QCA6174A. The driver is provided by Qualcomm with a driver date of 2018-06-24 and driver version of 10.0.0.714. I'm running Windows 10 in a 64-bit system with an Intel Core i9-8950HK CPU @ 2.9GHz x2 with 32 GB RAM.

Jesse,

Thanks for the advice. Unfortunately, I've already tried all of those things multiple times.

@DELL-Jesse L, I didn't think that I needed a firmware upgrade. Dell Command Update was telling me that I was updated and the website you linked also didn't recommend any updates. However, I did the firmware upgrade from the 19th of August (two days ago) and that fixed the problem. My bluetooth is working now.

Yes, I did. One of the sets of instructions for doing this recommended disabling the device, starting the service and then enabling it. I just did it again, just in case. The service was already running, so I disabled the bluetooth, stopped the service, started it again, then enabled the bluetooth. The device manager didn't show the error in the bluetooth, but it also wasn't possible to turn it on and test it, so I reboot my computer. Now, the device manager is again showing the error.

Sorcen,

Great to hear you got the issue resolved. Appreciate your letting us know. I will close the case. If you need other help please feel free to reach out to us.

Hello,

I'm having the same problem, I have a Latitude 3400 windows 10 64 bit.
My bluetooth simply stopped working, I have already made all the solutions proposed by the microsoft website,
as well as installing the drivers that are on the dell website in the support section, it is still getting the error cod 43.
I did the procedures that were put in this discussion and also nothing. I don't know what else to do, it just doesn't work.
Any idea ?

tks.

You can buy an external transmitter. If I hadn't gotten mine to work, I would have bought this:
