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! Tal Kain
