After even more digging, looks like the problem is with a parameter that
I suspect the tlp package (when using the computer without AC, on
battery-saving mode) and the command powertop --autotune are modifying:

Autosuspend for USB device BCM2045A0 [Broadcom Corp]

I've seen last message o my machine, but others have reported:

Autosuspend for USB device BCM920703 Bluetooth 4.1 [Broadcom Corp]

I think adding the file /lib/firmware/brcm/BCM-0a5c-6410.hcd fixes the
problem, but there might be other solutions (like not-installing tlp
package yet!!)
