I didn't notice that you were using Raspberry PI... To rule out USB
power issues, can you try attaching a powered USB hub on the RPi, and
then attach your BT dongle on it?

I always had strange/random problems on RPi with USB HW plugged
directly on the USB port (except for pen drives, which work fine),
even for devices which supposedly draw very little current.

Given that you are disabling duplicate filtering, every single
Advertising packet is arriving at the host, so it is certainly using
more power. Just not sure if that is the cause.

Best Regards,
