I (live) removed one USB BT dongle and plugged in a different one. I won't do that again. Now I can turn Bluetooth on, but no BT devices (speakers, keyboard) are ever found.

lsusb gives:

Bus 002 Device 006: ID 105b:e065 Foxconn International, Inc. BCM43142 Bluetooth module
Bus 002 Device 003: ID 0a5c:21e8 Broadcom Corp. BCM20702A0 Bluetooth 4.0

dmesg reports not finding firmware patches for either:

[    9.334699] Bluetooth: hci0: BCM: firmware Patch file not found, tried:
[    9.334704] Bluetooth: hci1: BCM: firmware Patch file not found, tried:
[    9.334706] Bluetooth: hci1: BCM: 'brcm/BCM43142A0-105b-e065.hcd'
[    9.334707] Bluetooth: hci0: BCM: 'brcm/BCM20702A1-0a5c-21e8.hcd'

I've seen other similar posts, but none shows two USB Bluetooth devices.

I put the keyboard and speaker in discovery mode.

As @Jeremy31 suggested, I got the firmware files from https://github.com/winterheart/broadcom-bt-firmware/tree/master/brcm and copied them into /lib/firmware/brcm.

I'm not sure if it was necessary but once the files recommended by @Jeremy31 were in the right place I did:

sudo chmod +wx *.hcd

sudo reboot
