My original question was this one: Bluetooth does not detect any devices [Ubuntu 16.04]

but it was marked as a duplicate however I could not find the solution even here: Bluetooth Broadcom 43142 isn't working on ubuntu

So, how can I fix this problem: "Bluetooth does not detect any devices. It just keeps searching and searching."

Here's a screenshot

It was recommended to me that I find another Windows driver for this adapter, which I do not know how to do.

[Edit] Output of: dmesg | grep -i blue; rfkill list

I would really appreciate some help here.

Thanks a lot in advance!

This is a new device. Download this driver

Open it with Archive Manager, then extract folder

drivers/DP_Bluetooth_16123/Broadcom/FORCED/8110x64/12.0.1.1011

There you will see bcbtums.inf file and firmware hex files.

The firmware for your 04ca:2012 adapter is BCM43142A0_001.001.011.0311.0339.hex.

Convert it to BCM.hcd using hex2hcd and copy it to /lib/firmware/brcm.

Generally speaking you can find Windows drivers for new BT adapters by internet search. In your case I found this driver by vid_04ca&pid_2012.
