my bluetooth is not able to detect any of the other bluetooth devices ... i was using windows before and the bluetooth was working fine ...
dmesg | grep firmware
results in "[ 15.275727] bluetooth hci0: Direct firmware load failed with error -2 "
lsusb | grep Bluetooth
results in "Bus 001 Device 004: ID 0a5c:21d7 Broadcom Corp. BCM43142 Bluetooth 4.0"
which clearly states that there is bluetooth adapter but i am having firmware issues.
