According to https://wireless.wiki.kernel.org/en/users/drivers/ath3k?s[]=ar3012, a combination of these files must be used, though I am not certain which ones would apply for my case:
For AR3012, you can find the “AthrBT_0x01020200.dfu” and “ramps_0x01020200_26.dfu” or “ramps_0x01020200_40.dfu” on the linux-firmware git tree: git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ar3k/modinfo ath3kandmodinfo ath3k | grep 3004confirm my expectation:filename: /lib/modules/4.4.0-59-generic/kernel/drivers/bluetooth/ath3k.ko firmware: ath3k-1.fw license: GPL version: 1.0 description: Atheros AR30xx firmware driver author: Atheros Communications alias: usb:v0CF3p3004d*dc*dsc*dp*ic*isc*ip*in* alias: usb:v04CAp3004d*dc*dsc*dp*ic*isc*ip*in*

Behavior
- The bluetooth icon may or may not load in the tray on login.
- The bluetooth toggle may or may not work.
- When the bluetooth toggle works, nothing is found on a search. Tried my phone and bluetooth audio.
