USB Bluetooth adapter stops working after 10.8.5 upgrade

Hi, same thing here, I obviously tried adding my "working but non-recognized out of the box" BT Adapter in Info.plist inside IOBluetoothFamliy.kext / BroadcomBluetoothHostControllerUSBTransport.kext, but that didn't do the trick...

From 10.8.3 to 10.8.4 that Belkin 4.0 BT adapter was perfectly working (BT chipset used inside is Broadcom 2070, the same as the one used in the IOGear BT 4.0 Adapter)

Now, I can see BT Icon in the menu bar, click on it, try to add devices or connect to my previsouly working devices... but nothing...

I can't seem to get any connection set up, no matter what...

I tried changing USB port, disconnecting/reconnecting Bluetooth, re-adding my devices, etc... nothing... :-(

Yes, because you have a BT adapter which is recognized Out Of The Box by OS X , without any plist editing needed, that's why it works on your Mac.

Mine isn't in the original KEXT and I need editing it, in order to get OS X to load the KEXT at boot, when encountering the right VendorID / ProductID couple, when parsing all USB devices attached.

But with 10.8.5, and Broadcom 20702A it simply doesn't... I really would like to know why...

...moreover knowing that the chipset used is the **** SAME as the IOGEAR one (only a matter of revision, so basically, they are the same when sepaking of "exchanging datas" with the device)

Edit: Ok, so, it's not even a revision problem, as I wrote a wrong Broadcom reference which actually is BCM20702A0, so strictly the same as the IOGear one...

Depends on what you want.

If a BT 4.0 is mandatory for you, go for the IOGear 4.0 BT which is easily available in the US (for us european, it's another story 😟)

If BT 2.0 is possible for you, then you have to check what adapter is fully supported OOTB, as I don't know them, I interested myself only in 4.0 BT USB Adapters...

I think I will go for a 2.0 BT USB Adapter with the capability of being able to use a BT keyboard in BIOS (for my Windows rig 🙂)

It would seem that the Supplemental Update has completely solved my problem with my ancient Cambridge Bluetooth dongle.

Hi everyone, I tried to do all the modifications suggested in the thread with no luck:

My USB adapter is a Sitecom 2.1 CN-516 and it shows on system information as:

The adapter is on (the blue led on it is flashing) but I can't de-activate it, nor find/link any device.
I've modified the kexts as suggested, adding the ProductID 1 and the VendorID 2578, repaired the disk permissions and flushed the cache but still nothing. Depending on the modification the bluetooth either pretends to work (it is on but can't connect/display any device) or it doesn't work at all.

This are the code lines that I added to the file

Any suggestion?

Thank you very much

You might want to consider starting a new discussion in Mavericks. Since this one is marked solved, less people are likely to look at it. You can link to this one.

I too have experienced issues with a Bluetooth USB adaptor and OS X 10.8.5.

I'm using a Bluetooth USB adaptor on my 2009 Mac Pro, as I have experienced issues with the builtin BT and my Magic Trackpad. Now, the Magic Trackpad will not pair with the USB adaptor anymore, so I'm forced back to the lag of the original Bluetooth hardware, which may well put me off my Trackpad entirely.

I too am having this issue on my Mac Pro. I have three various branded USB Bluetooth adapters, and NONE of them are working now 😟 So now I cannot use my Magic Mouse or Trackpad 😟

Please Apple fix this issue!

Can you tell me how you did in detai?

I'm having a the same issue.

My dongle's id is

Product ID 0x2101

Vendor ID 0x0a5c

Where shoud I correc the script?

Can I change the script with Textedit built in Mac OS?

@AwwwPuddin. Thanks for your code. Now the adaptor apperas in system infomamtion. and in the bluetooth preferences, my trackpad and mouse shows that they connected. But they don't work at all and the connection is easily disconnected. Do you have any idea?

Hmm. I have the exact same dongle, which also stopped working on my 2009 Mac Pro. I applied the fix as you did, but it didn't fix the problem. I still have no Bluetooth being recognized. Note that I have disconnected my internal Mac Pro's Bluetooth due to it being next to useless (poor reception).

Any other ideas?!?

I'll give it a go, thanks for the suggestion. I'm about half way through downloading the FULL OS X 10.8.5 installer (4.5GB) which I will save and do a clean install if re-enabling the internal BT doesn't work.

So I tried it. No dice. Mac Booted up with a supported BT connection (the internal one), but as soon as I plugged in my dongle, the bluetooth icon in t he menu bar became disabled like the original poster. So frustrated right now!

EDIT - oh and I downloaded the full OS X installer only to find the img file was corrupted.
