Hello.

A bit strange device. Can you please share info on which hardware (model of notebook) you running on? And please provide output from commands:

uname -a
dmesg | grep -i Bluetooth
lspci -nnvv | grep -A12 Broadcom
hciconfig -a

Help me to resolve the issue.

[winterheart]

Try these fw: bcm.zip

Rename each of these to /lib/firmware/brcm/BCM20702B0-0a5c-22be.hcd, reboot and try to configure Bluetooth.

Well, I don't see any compatible firmware. Officially Broadcom dropped support around 2011 and marked it as "no firmware needed".
