Bluetooth BCM20702A1 not working - Ubuntu 16.04

Question

The bluetooth service is running, but it is not working. I have tried this steps for BCM20702A1 (ID 105b:e066) but it didn't work. I noticed on my usb-devices that the product is listed as Broadcom BCM20702A0, but on lsusb it shows 105b:e066 Foxconn International, Inc.

uname -a

Linux robson-vb 4.8.0-58-generic #63~16.04.1-Ubuntu SMP Mon Jun 26 18:08:51 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Any ideas?

Solution

This should work

sudo apt-get install build-essential git
git clone https://github.com/jeremyb31/bluetooth-4.8.git
cd bluetooth-4.8
cp /usr/src/linux-headers-$(uname -r)/.config ./
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make -C /lib/modules/$(uname -r)/build M=$(pwd) modules
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo depmod -a

Reboot and see if it works

After a kernel update the steps will need to be done again

cd bluetooth-4.8
make -C /lib/modules/$(uname -r)/build M=$(pwd) clean
cp /usr/src/linux-headers-$(uname -r)/.config ./
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make -C /lib/modules/$(uname -r)/build M=$(pwd) modules
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo depmod -a

What kernel are you using- uname -a

[RobsonOS]

Hi Jeremy, Linux robson-vb 4.8.0-58-generic #63~16.04.1-Ubuntu SMP Mon Jun 26 18:08:51 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

[Jeremy31]

Can you file a bug report at help.ubuntu.com/community/ReportingBugs that will help get a permanent fix in the kernel. Pilot6 has already committed a fix to the Linux kernel but I think Ubuntu likes to see a bug report before they will include anything new in 4.4 or 4.8/4.10 kernels

[RobsonOS]

Hey Jeremy, thanks for the reply. It didn't work, there was an error: sudo cp btusb /lib/modules/$(uname -r)/kernel/drivers/bluetooth/ cp: cannot stat 'btusb': No such file or directory

[RobsonOS]

I realized you meant the file btusb.ko. It works like a charm now. Thanks

[Pilot6]

@Jeremy31 Did you send the patch upstream?

[Pilot6]

I see that it is not there. Will you send it?
