Bluetooth adapter missing

After years of reliable service, my bluetooth adapter quit last night on my Mac Pro 5,1 (mid 2010) 12 core tower. I have been using Apple's wireless keyboard, magic mouse, magic trackpad, bluetooth keypad, and logitech wireless headset until I went to launch a Steam game and the mouse just quit moving. Of course I changed batteries, etc and finally found and tried my old wired keyboard and mouse.
When I go into System Information and look at the Bluetooth section under Hardware I have ?No information found" for the bluetooth adapter. Everything else looks like it should with no errors. The bluetooth status in the status bar is grayed out with a Not Available message.
So I am looking for an apple replacement part for the bluetooth adapter as I understand that EFI firmware updates require an integrated bluetooth adapter or you lose keybpard support for that process I would also like to know if anyone has tried other third-party bluetooth dongles or add-in cards with success.
Thanks for any advice you might have.

I'm back and working, I reset the NVRAM.
To do so, follow these simple steps:
Power off the Mac Pro
On a wired keyboard press Command+P+R and hold them
Power on the Mac Pro
While continuing to hold the COMMAND+P+R keys wait for the system to boot into the System Utilities screen. At that point all the wireless (bluetooth) devices were working so I restarted the Mac.
If anyone has any third-party bluetooth adapter suggestions I'd love to hear about them all the same.

  • D-Link DBT-120 USB Bluetooth Adapter: connecting to headsets or not???

    Hi there!
    I want to use a headset with my G5, using a BT USB adapter. Mine doesn't work, so I'm thinking - unhappily - of buying a D-Link DBT-120 USB Bluetooth Adapter.
    But: in the Apple Store, they say it does not work with headsets!!!
    On the other side, people in the board here are claiming that it works, if you apply the firmware updater.
    Which one is right??? I can hardly belive that Apple using untrue negatif customer feedback as a marketing strategie... so I'm a bit confused.
    ==>>> I would like to hear from people who are using the D-Link DBT-120 USB Bluetooth Adapter if they are able to connect to a headset or not (even people not having a headset can test this, just run the BT hardware wizard, selecting headset, and see if there is the error or not).
    Thanks a lot.
    Gilbert

    Using a headset needs several steps even needed if you have the latest computer or Mac OS X release. Please make sure to follow them in order.
    Download the Apple Bluetooth Firmware Updater
    Install it
    Launch it from Applications > Utilities > Bluetooth Updater
    Apply it to your adapter (takes very long).
    Start the Apple Bluetooth Assistant and select Headset. Do not use anything else!
    Make your headset Bluetooth visible. Look up the manual of your headset how to do that.
    Now select the headset in System Preferences > Sound.
    In most cases step 3 is missed. You have to start the already installed updater yourself (do not ask me why).

  • Nokia HDW - 3 with Silicon Wave Bluetooth Adapter ...

    Hi,
    I have the following configuration:
    Nokia HDW - 3
    Silicon Wave Bluetooth Adapter
    Windows XP Pro SP3.
    Many years ago I was able to get this headset working with another Bluetooth Dongle we had bought at the time.
    Since then I have bought the Silicon Wave Bluetooth Adapter and not been able to get my bluetooth headset to work with the adapter and my PC. All three are working seperately, I know this because I've run numerous tests but they are not playing well together.
    Is there something I am missing? Maybe there's some additional software out there I am not aware of that I can use to get Skype working with the hardware I have mentioned?
    Thanks,
    James

    I figured it out...
    On your Wave III remote, press "Aux" until "Bluetooth" appears, then hold down the presets "5" button until "Discoverable" appears. Open your mac's bluetooth in system preferences and it should show up and pair. It worked perfectly for me.

  • Satellite A500-011 PSAR0C-01100D - internal Bluetooth adapter

    I have Satellite A500-011 PSAR0C-01100D, I'm looking for an internal Bluetooth PCI adapter that slides in, on the side of the laptop into the pci card slot. without opening the computer)
    Can someone help me find the part number ?
    I remember seeing it in the toshiba site,a while back, but not there anymore, can't find it. I would like to order one.
    i have an external USB Bluetooth adapter but it's a bit flaky and it sticks out and gets caught in the bag etc.
    There is a internal module available but I don't want to open up the case and damage it.
    thanks

    *Replacing Wireless Card with WiFi & BT Combination Card.*
    Hopefully it will be compatible with the computer. Make sure that it is half PCI-e size.
    Example of what it should look like: http://www.compactpci-systems.com/products/id/?45200
    First, the laptop should be placed bottom side up to expose the doors.
    The centre most door that uses one screw to open should be the one to open.
    When open, you should see the RAM exposed.
    In addition to this, there is the wireless modem card.
    Unscrew two 2.5x3 screws that secure the card.
    Remove from the slot.
    Take the Wireless WiFi & BT combination card, and slip it into the slot.
    Secure with the two screws.
    Close the lid, and secure with screw.
    Install any necessary software and drivers. . .
    *For dedicated BT:*
    For A500 models, you need a version 2.1 + EDR (antenna on mobile type) model for bluetooth.
    This would involve removing the keyboard and acccessing the top of the motherboard; a more intriciate process.

  • [Solved] Can't Get Bluetooth Adapter To Run

    Hi adam,
    I'm running 64bit Arch on a Studio 1557 with an integrated usb bluetooth adapter (BCM2046).
    In 2011 I had the very same problem you describe and got it fixed. Let me explain:
    The bluetooth adapter has 2 modes of operation: HID mode and HCI mode.
    In HID mode, it presents itself as a keyboard/mouse input device (in your case 413c:815[8/7]).
    This allows you to use e.g. a bluetooth mouse that has been paired earlier - even if your OS doesn't support bluetooth.
    In HCI mode, the device presents itself as a regular bluetooth adapter which can be used by your bluetooth stack (e.g. bluez) - that's what we want.
    The problem back in 2011 was, that my adapter would default to HID mode and to switch it to HCI mode I had to use the 'hid2hci' tool (now part of bluez-utils).
    For some time now bluez ships a udev rule which takes care of switching modes so everything worked flawlessly.
    A couple of weeks ago, however, the problem resurfaced and I haven't found a fix yet.
    I noticed that the udev rule isn't triggered anymore and running hid2hci (/lib/udev/hid2hci) manually doesn't work either (gives an error saying 'unable to handle [devpath]').
    The only way to use the bluetooth adapter in arch for me is to boot Windows inside a Virtual machine, attach the USB touchpad device (the HID proxy) and let Windows switch it to HCI mode.
    This, however, only lasts until I reboot/resume from standby.
    I believe this regression was caused by a package upgrade, since an older arch installation I had lying around still recogniced the adapter while an up-to-date installation wouldn't.
    Unfortunately, said lecacy installation is now gone and downgrading arch to a point before the regression doesn't seem feasible.
    Any suggestions are more than welcome!
    So long,
    rev

  • USB Bluetooth adapter stops working after 10.8.5 upgrade

    For several months I've been using an IOGear USB Bluetooth adapter and a USB KVM to share my Magic Trackpad between a Mac Mini and a MBP, both machines happily running 10.8.4.
    Tonight I upgraded my MBP to 10.8.5 and now Bluetooth is apparently disabled when I have the USB adapter plugged in:
    Now I'm left with the unappealing decision of using my Trackpad with only my Mac Mini, my MBP, or constantly repairing it with either to share.
    I've been shockingly happy with this little trick, but I guess it was too good to last. Anyone have any ideas why using a USB Bluetooth adapter would stop working? Maybe I need a different adapter now?

    Thanks! That solved my problem. I just had to swap in my device id which was different than yours.
    I converted my USB adapter's idProduct value from hexidecimal (0x2101) into decimal (8449) and added this configuration:
                        <key>BroadcomUSBBluetoothHCIController_Dongle - IOGear2</key>

    See this -> Belkin TuneStage for iPod

    is pretty old. Don't know if they have updated it or even if it is still sold.
