>>> Where did you get your atheros board/card since I couldn't find that board here. Is it a laptop? The BT firmware driver was trying to load AthrBT_0x00000200.dfu file and it got failed because no firmware file was present. But 0x00000200 means fw_version.rom_version which coming from controller chip, however, I haven't seen this version on Atheros chipset.

That's why you cannot bring up your card with ath3k driver. I knew it was not a good idea as it was early stage to develop the card so that next version of ROME USB card(v3.0 or v3.2) will use different PID/VID as you can see below.

Hi Ben,

I added that line to my btusb.c; did a mrpropery, copied my .config back
into the source tree, disabled ATH3K in menucofnig, made the bzImage and
rebooted. The firmware you attached is in /lib/firmware/qca.

I enabled debugging (FLAGS_btusb.o := -DDEBUG in the Makefile) so I
could get some more info, and discovered I also have to delete this line
or it will match the ath first:

{ USB_DEVICE(0x0cf3, 0x3004), .driver_info = BTUSB_ATH3012 }

So then I saw

[    1.263991] usb 3-1.3: new full-speed USB device number 3 using ehci-pci
[    1.277022] usb 4-1.8: new full-speed USB device number 3 using ehci-pci
[    1.350050] usb 3-1.3: New USB device found, idVendor=0cf3,
idProduct=3004
[    1.350051] usb 3-1.3: New USB device strings: Mfr=0, Product=0,
SerialNumber=0
[    1.350461] intf ffff88041bf62400 id ffffffff81d83bc0
[    1.350462] BT Device Info 0
[    1.350463] BT Device Info (after matching) 32768
[    1.350466] In Rome Block
[    1.350546] input: ETPS/2 Elantech Touchpad as
/devices/platform/i8042/serio1/input/input10
[    1.350671] hci0
[    1.350879] Bluetooth: hci0: don't support firmware rome 0x200
[    1.364795] usb 4-1.8: New USB device found, idVendor=1770,
idProduct=ff00
[    1.364797] usb 4-1.8: New USB device strings: Mfr=1, Product=1,

[    1.364798] usb 4-1.8: Product: MSI EPF USB
[    1.364799] usb 4-1.8: Manufacturer: MSI EPF USB
[    1.364800] usb 4-1.8: SerialNumber: MSI EPF USB

So those BT Device Info statements I added in the probe function. "In
Rome Block" I added right after "if (id->driver_info & BTUSB_QCA_ROME) "
and you can see where that error comes from.

And that comes from...oh it checks another table...okay so I added the
following to qca_device_info

        { 0x00000200, 28, 4, 18 },

and now I get;

[    1.357942] intf ffff88041ba5bc00 id ffffffff81d83bc0
[    1.357943] BT Device Info 0
[    1.357944] BT Device Info (after matching) 32768
[    1.357946] In Rome Block
[    1.358113] hci0
[    1.358516] bluetooth hci0: Direct firmware load for
qca/rampatch_usb_00000200.bin failed with error -2
[    1.358517] Bluetooth: hci0: failed to request rampatch file:
qca/rampatch_usb_00000200.bin (-2)

So progress. It's attempting to load the firmware and failing. Are those
the right numbers for the device_info block?
