It looks like the problem is the kernel:

[   55.796659] usbcore: registered new interface driver btusb
[   55.799361] usb 1-4: Direct firmware load for ar3k/AthrBT_0x11020000.dfu 
failed with error -2
[   55.799368] Bluetooth: Patch file not found ar3k/AthrBT_0x11020000.dfu
[   55.799373] Bluetooth: Loading patch file failed
[   55.799420] ath3k: probe of 1-4:1.0 failed with error -2
[   55.822336] usbcore: registered new interface driver ath3k

But rather than associate this bug with the PCI device "AR9462" we
should probably focus on the USB device "13d3:3393 IMC Networks". Sounds
related to bug 1965953.
