Still issue using 4.2.0-18-generic [ 8.720655] usb 3-1.3: Direct firmware load for ar3k/AthrBT_0x00000200.dfu failed with error -2 [ 8.720659] Bluetooth: Patch file not found ar3k/AthrBT_0x00000200.dfu [ 8.720661] Bluetooth: Loading patch file failed [ 8.720666] ath3k: probe of 3-1.3:1.0 failed with error -2 [ 8.720691] usbcore: registered new interface driver ath3k Still issue using 4.2.0-21-generic There does not seem to be proper firmware support for the chip. According to mainline code, it should be loading firmware ar3k/AthrBT_0x01020200.dfu. But the firmware download times-out. Not sure whether setting "driver_info = BTUSB_QCA_ROME" as suggested in http://marc.info/?l=linux-bluetooth&m=144633933801493&w=2 would work either. The rom version returned by this chip is 0x1020200. This version is not present in qca_devices_table, which again will result in error.

Anyway, here was the last e-mail I sent about this: http://permalink.gmane.org/gmane.linux.bluez.kernel/63192 and then I gave up and bought and external bluetooth dongle...which broke last week. So I finally replied to that e-mail. So according to that thread, I don't actually have an ath3k card. It's uses the same USB ID number, but it's actually a QCA Rome chipset. So that patch tries to get the kernel to ignore the ath3k match and instead load the QCA firmware. On my MSI WS-60, it loads the firmware, then fails when I try to run "power on" within the "bluetoothctl" command line app (same if I use hciconfig instead as started in a previous e-mail in that thread).

(Wi-fi works fine in stock 4.3.0 with ath10k_pci) Hi I have an Eurocom P5 with the same hardware and the fix provided in the previous link works perfectly.
