Bluetooth firmware for device 13d3:3362 randomly fails to load 13d3:3362

[Edi Ćiković]

1. Linux Mint 17 64-bit cinnamon
2. When booting my laptop bluetooth works in 20% of boots. When it does not work I get the following output in dmesg:
 [ 15.685441] Bluetooth: Error in firmware loading err = -110,len = 448, size = 4096
[ 15.685452] Bluetooth: Loading patch file failed
Sometimes I get a different error such as :
[ 16.566398] Bluetooth: hci0 command 0x1002 tx timeout
[ 18.572068] Bluetooth: hci0 command 0x0c52 tx timeout
[ 20.577695] Bluetooth: hci0 command 0x0c45 tx timeout
[ 22.583266] Bluetooth: hci0 command 0x0c58 tx timeout
[ 24.588880] Bluetooth: hci0 command tx timeout

5. This bug occurs only sometimes, although most of the time it doesn't work. The interesting thing is when booting from a USB it seems to have a better chance of working. I suspect there is a race condition problem somewhere, because of the random nature of this bug. I have tried everything I was able to find online in order to get this to work, however nothing helped. The bluetooth is not rfkill blocked. hcitool dev returns nothing

lsusb -v returns the following for this device

A fix that works for me is to blacklist the ath3k and btusb modules and then use /etc/rc.local to modprobe both modules in.
