Im running a Dell Precision 5530 with Intel 9260 combined WiFI and Bluetooth cards.
Lately I had the feeling that my battery runtime went really bad and indeed the fans where running quite often. With powertop I found out that the service
consumes almost 13-15 W constantly.
I know that I could just kill the process, but this would not solve my issues, since I use Bluetooth for my mouse.
Is there a way to fix this issue?

I guess btusb might be part of the kernel and there might not be an easy remove, reset and reinstall approach.
