Hello I am attempting to get the bluetooth working that is on my Asus Maximus VI Extreme motherboard going. It is a mPCIE card but regesters as a usb. Here is the hardware info:

08:00.0 Network controller: Broadcom Corporation BCM4352 802.11ac Wireless Network Adapter (rev 03)I was following this thread to recreate what was already accomplished for a BCM20702A0 bluetooth
I downloaded the windows driver from the asus website, looked up 0b05:17cf and found it used BCM20702A1_001.002.014.1315.1350.hex firmware. I then extracted this file and used hex2hcd to convert it to an hcd file.
sudo hec2hcd BCM20702A1_001.002.014.1315.1350.hex /usr/lib/firmware/fw-0b05_17cf.hcdI copied in my device id into /sys/bus/usb/drivers/btusb/new_id as instructed early in the thread:
sudo echo "0b05 17cf" > /sys/bus/usb/drivers/btusb/new_idI wasn't even sure if that was needed as lsusb already listed the device under that vendor id and product id and am not really sure what this accomplishes but I did it anyway.
I created a system unit file to load the firmware using a script.
[brian@prometheus ~]$ cat /etc/systemd/system/loadfw.service
[Unit]
Description=Load firmware into BCM20702A0 bluetooth USB adapter
After=basic.target

[Service]

ExecStart=/usr/bin/start_BCM20702A0.sh
[Install]
WantedBy=basic.target
WantedBy=suspend.target
WantedBy=hibernate.targetI also copied the following into the script file and made it executable:
[brian@prometheus ~]$ cat /usr/bin/start_BCM20702A0.sh

#

# logfile does not exist, so create it
touch $logfile
fi

echo $entrytime " applying rampatch to BCM20702A0 bluetooth adapter" >> $logfile

echo "-------------------------------------------------------" >> $logfileRunning sudo systemctl start loadfw.service acts like it completes successfully however device hci0 could not be found and this is the output of systemctl status loadfw:

After further messing around I decided to su to root and ran this command:
[brian@prometheus ~]$ su
Password:
[root@prometheus brian]# sudo echo "0b05 17cf" > /sys/bus/usb/drivers/btusb/new_id
[root@prometheus brian]# bluetoothctl
[NEW] Controller 24:0A:64:07:25:44 prometheus [default]
[bluetooth]# So this command needs to be actually ran as root and not just sudo.
I then changed my script file to include it and it now works. I also added a modprobe btusb to the systemd file as it wasn't getting automatically loaded each boot. I am now happy that I have a working bluetooth device.
Here are my updated systemd file and script
/etc/systemd/system/loadfw.service file:
[Unit]
Description=Load firmware into BCM20702A0 bluetooth USB adapter
After=basic.target
After=suspend.target
After=hibernate.target
[Service]
Type=oneshot
ExecStart=/usr/bin/modprobe btusb
ExecStart=/usr/bin/start_BCM20702A0.sh
[Install]
WantedBy=basic.target
WantedBy=suspend.target
WantedBy=hibernate.targetAnd here is my updated script file:
# cat /usr/bin/start_BCM20702A0.sh
#!/bin/bash
#
# BCM20702A0 BT Adapter upload rampatch
# env Variables
logfile=/var/log/rampatch.log
# logfile check
if ! test -f ${logfile} ; then
# logfile does not exist, so create it
touch $logfile
fi
echo "-------------------------------------------------------" >> $logfile
entrytime=$(date +"%Y-%m-%d %H:%M:%S")
echo $entrytime " applying rampatch to BCM20702A0 bluetooth adapter" >> $logfile
#Create the device
/usr/bin/echo "0b05 17cf" >> /sys/bus/usb/drivers/btusb/new_id
# wait for hci0 to become available and usable
sleep 1
/usr/bin/brcm_patchram_plus_usb --patchram /lib/firmware/fw-0b05_17cf.hcd hci0 >> $logfile
entrytime=$(date +"%Y-%m-%d %H:%M:%S")
echo $entrytime " ..done" >> $logfile
echo "-------------------------------------------------------" >> $logfileFor me this issue is now solved.

@Zenther
I have a ASUS Z97 Pro motherboard, it also uses Broadcom BCM20702A0 bluetooth chip, and I've followed your instructions in every step, no luck, the `hcitool scan` still can't find anything. Where do you download the `BCM20702A1_001.002.014.1315.1350.hex` file?, can you send one copy to me? thanks.
For me,
$ echo "0b05 17cf" | sudo tee /sys/bus/usb/drivers/btusb/new_id
will make `hcitool dev` works, it shows a hci0 device.
I downloaded the windows driver by searching `Z97-Pro` in ASUS's website. And after load a firmware,
$ sudo brcm_patchram_plus_usb --patchram BT_Win7-8-8-1_VER6514800_VER12009350/Bluetooth/Win7/Win64/BCM20702A1_001.002.014.1315.1350.hcd hci0
# the kernel has this error
kernel: Bluetooth: hci0 command 0x0c03 tx timeout# hciconfig -a
Can't read local name on hci0: Connection timed out (110)# hcitool scan
kernel: Bluetooth: hci0 command 0x0c03 tx timeout
without a firmware, `hcitool scan` has an empty result and `hciconfig -a` has no error.
