[Bug 1406014] Re: Bluetooth: can't load firmware, may not work correctly

 

Hi Christopher,

With kernel 3.19-rc1, Bluetooth still does not work. However, the
behavior changed. This is what dmesg shows after unloading and loading
btusb:

[ 1058.704086] usbcore: deregistering interface driver btusb
[ 1058.752148] usbcore: registered new interface driver btusb
[ 1058.761677] bluetooth hci0: Direct firmware load for brcm/BCM20702A0-0a5c-21e6.hcd failed with error -2
[ 1058.761683] Bluetooth: hci0: BCM: patch brcm/BCM20702A0-0a5c-21e6.hcd not found

I've also installed the latest firmware package
