Description of problem:
I can't connect some Bluetooth devices. Driver Broadcom BCM2046B1 is missing.
I have Mac mini with with three network hardware:

Broadcom BCM4331 802.11a/b/g/n for Wi-Fi
Broadcom NetXtreme BCM57765 for Ethernet
Broadcom BCM2046B1 USB 2.0 for Bluetooth

With driver non-free BCM4331 works fine but BCM2046B1 is not found. I don't know what driver I have to install.
With Mageia 8 there weren't problem, the HW was recognize at install.

Version-Release number of selected component (if applicable): Mageia 9 RC1
