Comment 303 for bug 1383184

As rugby world cup is happening and i'd like to use external sound, I realize that indeed, blueetooth is not working. As many asked, is there a work around?
I get the exact same error message as many folks above, in dmesg:

[ 3.767091] usbcore: registered new interface driver btusb
[ 3.772611] usb 1-9: Direct firmware load for ar3k/AthrBT_0x00000200.dfu failed with error -2
[ 3.772614] Bluetooth: Patch file not found ar3k/AthrBT_0x00000200.dfu
[ 3.772615] Bluetooth: Loading patch file failed
[ 3.772619] ath3k: probe of 1-9:1.0 failed with error -2

really sorry to bother, bluetooth is not as critical but still a nice thing to have! :-)
Many thanks
