[solved] Asus N550JV High Sierra AzureWave BCM94352HMB bluetooth fix

[sandro_desktop]

Hi everyone,

I`ve installed High Sierra on my Asus N550JV laptop;

wifi-BT card is AzureWave BCM94352HMB ... wifi works perfectly but bluetooth doesn't, because there isn't any USB bluetooth module detected by the system profile;

so I`ve patched IOUSBHostFamily.kext following this video tutorial:

bluetooth now works very well, but USB 3.0 ports are detected as USB 2.0 ...

every suggestion would be very appreciated...

thanks!

There's no need to patch IOUSBHostFamily.kext;

just install FakePCIID_XHCIMux.kext and USBInjectAll.kext in S/L/E;

thank you feartec and a special thank to Rehabman for his precious kexts

I have a similar problem with my Intel bluetooth module. While Intel wifi isn't supported, the Bluetooth part is. But sometimes the Bluetooth USB device isn't detected and that particular port has nothing connected to it if I look on ioreg. I have FakePCIID_XHCIMux.kext and USBInjectAll.kext, USB 2.0 and 3.0 ports are correctly routed, but I still have no bluetooth.

to avoid access the system problem, it's better to copy USBInjectAll.kext onto the desktop ed install it not in S/L/E but only in L/E using Terminal:

sudo cp -R ~/Desktop/USBInjectAll.kext /Library/Extensions/

sudo chmod -R 755 /Library/Extensions/USBInjectAll.kext

sudo chown -R root:wheel /Library/Extensions/USBInjectAll.kext

cheers!

update:

installed High Sierra beta 4;

FakePCIID_XHCIMux.kext is useless for the purpose;

just copy USBInjectAll.kext onto the desktop ed install it into L/E using the following Terminal command:

sudo cp -R ~/Desktop/USBInjectAll.kext /Library/Extensions/

cheers!

FakePCIID_XHCIMux.kext only works if FakePCIID.kext is also installed.
FakePCIID_XHCHMux.kext + FakePCIID.kext allows you to route HS ports on XHC to EHCI.

update:

it works better using all these 3 Terminal commands:

sudo cp -R ~/Desktop/USBInjectAll.kext /Library/Extensions/

sudo chmod -R 755 /Library/Extensions/USBInjectAll.kext

sudo chown -R root:wheel /Library/Extensions/USBInjectAll.kext

your USBInjectAll.kext installed into L/E makes bluetooth simply perfect now...

tested with Philips Fidelio BT Headphones, audio signal is very good with a wider listening range...
