"The Bluetooth Service service terminated unexpectedly," once every minute.

I’m using Windows 8.1. Soon after installing the Pluggable USB Adapter (model: USB-BT4LE), I noticed that the windows where I was typing lost focus for a second every minute or so, which made writing notes an annoyance.

After Googling a bit, I read someone recommending to check the event viewer (Control Panel\System and Security\Administrative Tools) and see what’s in Windows Logs -> System. Sure enough, the following error was happening practically every minute:


Apart from this, the BT USB adapter is working and connecting to my headset… but it’s crashing/restarting over and over gain every minute. Does anyone have an idea of what’s going on?


Here are the full details from the Event window (the same thing going on every minute):

Even though it does not mention the error message I was getting, I decided to try the “Using the PNPUTIL Command to Discover and Delete Conflicting Drivers (VERY Advanced Technique)” method on the PlugDebug page… since I had a hunch that my problem had to do with conflicting drivers.

I followed all the steps, and that seemed to do the trick. The screen no longer hiccups, and the Event Window no longer shows the error (*knocks on wood*). Which is great, since I was *this* close to uninstall everything and return the product to Amazon.

Posted this just in case anyone else runs into the same problem, and doesn’t know what to do (like me). Thanks to Pluggable for leaving such detailed troubleshooting article.


Thank you for your thread, sorry we didn’t see this earlier!

I’m glad to hear that things seem to be working well now after going through the driver removal procedure.
