Subject: Adding supprot for Bluetooth 0x13d3, 0x3404 "BCM20702A0" on asus
 G750JX

Hi,

I'm using linux OpenSuse 13.1 with kernel 3.11 on the Asus ROG G750JX-T4215H
machine:
# uname -r
3.11.6-4-desktop

It's hard to find something about this bluetooth device but finally i found
some patch for the same device BCM20702A0 on another hardware but on this
computer Asus P8Z77-V Deluxe : 
http://blog.tkassembled.com/301/patching-btusb-to-enable-compatibility-with-the-bcm20702a0-chip/
http://linux-kernel.2935.n7.nabble.com/PATCH-Bluetooth-Add-support-for-BCM20702A0-0b05-17b5-td195933.html

I found that this bluetooth is integrated but connected to the USB-hub ! And
after adding the following line to drivers/bluetooth/btusb.c and recompiling
it and using it (# modprobe btusb), the device is now enabled
{ USB_DEVICE(0x13d3, 0x3404) }, /*on ASUS G750JX vendor INC*/

QUESTIONS:
Do i have to make other actions to enable the device completely ?
I don't know how to make the patch file for what i did, if somebody can do
it or explain me how to do it, i have enough aknowledge in system admin to
do it.

Because it's enabled with the applet bluedevil integrated in kde4 but i
can't connect to the desired device (mouse with bluetooth Razer Orochi 2013)

# hwinfo --mouse (part of the specified mouse)
