Ubuntu: Installing a missing ath3k firmware

While trying to prepare a new Ubuntu box to use a new card based on the Atheros chipset, I encounter the following error:

Bluetooth: Firmware file "ath3k-1.fw" not found

According to http://wireless.kernel.org/en/users/Drivers/ath3k:

ath3k is the Linux Bluetooth driver for Atheros AR3011/AR3012 Bluetooth chipsets.

I saw this blog post: http://hexwave.blogspot.com/2011/04/debian-6-with-atheros-3011-ath3k-usb.html
So I decided to try installing the package linux-firmware which contains the relevant file (I used dlocate to

$ dlocate linux-firmware | grep -i ath3
linux-firmware: /lib/firmware/ath3k-1.fw

or you can find it by searching for ath3k:

$ dlocate ath3k-1.fw
linux-firmware: /lib/firmware/ath3k-1.fw

I just ran:

# apt-get install linux-firmware

and it fixed it by installing the missing firmware file.

Good luck!
