Comment 41 for bug 1764645

If anyone wants to test this fix

sudo apt install git build-essential dkms
git clone https://github.com/jeremyb31/newbtfix-4.15.git
sudo dkms add ./newbtfix-4.15
sudo dkms install btusb/4.0

If a fix is released for 4.15

sudo dkms remove btusb/4.0
sudo rm -r /usr/src/btusb-4.0
