DESCRIPTION
 The 
aubtfwl driver manages automatic loading of firmware on the Atheros AR3011 Bluetooth chipset. The firmware file 
ath3k-1.fw should be obtained and placed in a 
ubt/ directory in the search path of the 
firmload(9) kernel subsystem. Upon attachment, the 
aubtfwl driver will load this firmware file and the device will detach and reattach as a generic Bluetooth device using the 
ubt(4) driver.
The firmware file can be obtained from the Linux firmware git repository at http://git.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git.
