Bluetooth device stopped working

hey,
i was wondering if anyone could help me ???
in windows, my bluetooth stopped working all of a sudden it can't find anything and no other devices can see it's look like the device has been switch off.
btw i'm using snow leopard and i just installed windows vista Ultimate.
and it's driving me insane just when i got the drivers working (the sound, the trackpad , ... ) this happened

I have the same bluetooth controller (0cf3:3005, Atheros AR3011) on my laptop (ASUS K53SV) and have the exact same problem. Bluetooth works for a while until tx errors start showing up:
[24952.326871] Bluetooth: hci0 command 0x0c1a tx timeout
[24954.332842] Bluetooth: hci0 command 0x0c52 tx timeout
[24956.338826] Bluetooth: hci0 command 0x0c24 tx timeout
[24958.344882] Bluetooth: hci0 command 0x0405 tx timeout

[25051.014213] Bluetooth: hci0 command 0x0c14 tx timeout
[25075.805968] Bluetooth: hci0 command 0x0408 tx timeout
Resetting the bluetooth device works sometimes but not always. There is always a chance that the device will just become unresponsive to any kinds of commands:
# hciconfig hci0 reset
Can't init device hci0: Connection timed out (110)
I've tried various methods (block/unblock them with rfkill, `rmmod btusb` & `modprobe btusb`, etc) but none works after the device is "dead". The only way to recover seems to be powering off the laptop (simply rebooting doesn't fix the problem).

The light on the panel of machine turns off for a couple of seconds when the machine is turned on but after that the light is turned off and it never come back on unless or untill next start. (the light of BLUETOOTH device is turned on even before something appears on the screen).
When I try to install drivers it asks to check the device is connected properly etc, but neither I can install the driver nor it is useable.
Please help me.

Your Bluetooth device inside your computer seems to be turned off. Press Fn + F5 key and see if your Bluetooth Radio is turned on.

Bluetooth Mouse stops working after software updates

Hello,
I've been using a Bluetooth mouse with my X220 Tablet for several months now. After fiddling with device manager to ensure that the Thinkpad Bluetooth device does not have the "Allow the computer to turn off this device to save power" setting set, things were working perfectly.
However, after running through some windows & Lenovo updates, the mouse now seems to work for a while, but after any idle time, the mouse stops working. Turning the mouse off & back on seems to cause it to reconnect, and it works until the next time it goes idle for 2 minutes.
I've gone through device manager, and made sure both the Bluetooth & USB Root devices are set not to power down (per http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/Bluetooth-mouse-stops-working-from-time-to-tim... ), but still no luck.
The software updates applied from the Lenovo System Update tool were:
ThinkPad Power Management Driver: 1.67.04.05
ThinkPad Power Manager: 6.64.4
Lenovo Solution Center: 2.4.002
Intel G1/G2 Display Driver: 9.17.10.3347
Also, some windows updates which don't seem related (mostly security), but I can lookup the list of KB numbers if helpful.
Are there any known issues with the power manager updates that might affect this? If so, what's the best way to revert to the last working version?
Thanks!

Try doing a PRAM reset and see if that helps, also put in new batteries as that may make a difference.

Yosemite - Bluetooth speaker stops working

I have an issue where my Bluetooth speaker stops working. It shows up on the devices list under Bluetooth but when I try to connect it does not do anything.
Rebooting fixes the problem. But then the next day when I try to use the speaker again it does not work.
This started happening with the upgrade to Yosemite.
Please advise, thanks,
OS X 10.10.1. MacBook Pro 15" Retina mid 2012

Scratch that. Things have improved in 10.10.2 - I am able to reconnect to the Bluetooth speaker more often, but it does sometimes fail and I have to reboot.

My bluetooth suddenly stopped working soon after I upgraded to OS 10.9.4. I rebooted SMC, didn't work. Any other ideas?

My bluetooth suddenly stopped working soon after I upgraded to OS 10.9.4. I rebooted SMC, didn't work. Any other ideas? Don't know if it's related to the upgrade. I see other complaints about bluetooth in the thread but none of the solutions offered there have worked for me.

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

CDrom Device stopped working

We purchased an Acer package about 3 weeks ago that came with an epson printer. The CD device was working when I loaded a photo gallery file and a game. When I was about to install the printer - the CD device just stopped working at all. An error under Device Manager shows 'A driver (service) for this device has been disabled. An alternate driver may be providing this functionality. (Code 32)'
At the same time, I was waiting for my internet provider to reinstall my internet because I found out that I can't go wireless. A week later my internet was finally up and working. Someone suggested to do a system restore from the day the CD device last worked. I did and it did work. I was finally able to load the epson printer and it was all working but by this time....my internet connection was lost. 'was wondering if it had to do with the timing that the date I picked....I had no internet connection yet. I went ahead and picked another date after my internet was installed and once again, the CD device stopped working and whatever installation I did with the printer was not located. So I don't know what to do. I know I'm still in warranty with Best Buy but is this something that someone can help me out from Best Buy or Geek Squad over the phone or do I have to bring the entire system to them. I have an online business and I can't really afford right now to lose more days since it took days already to have my internet back in order. Please help.

Perhaps an expert can come up here and tell you how to remove the terms 'upper filters" and "lower filters" from a certain part of the registry. I dont feel adventureous enough to explaining it withotu sounding like a dummy

Bluetooth keyboard stops working

My bluetooth keyboard stops working while I use Photoshop CS4. It happened 4 days ago. I called applecare and they asked that I take the keyboard into a dealer. Keypad worked at the dealer. Brought it home and it worked.
When I pair the keyboard to bluetooth the keyboard functions, but in all other applications it doesn't. I think it must be the computer an not the keyboard.
konabill

It's been a while but I am sure the issue lies with the bluetooth now. I did the SMC reset and the same issue only happened once since. This time I plugged in my logitech USB wireless mouse and it worked fine. I tried to disconnect my Apple bluetooth mouse and couldn't get it to connect again. I restarted the machine by clicking Apple->shut down->restart and when the computer restarted, neither the keyboard nor the mouse worked. I again used the Logitech wireless mouse to try to see my bluetooth setting. However I get the message of "bluetooth not available". I'm guessing my bluetooth unit in this new iMac isn't functioning properly. Any ideas or suggestions would be much appreciated.
Thanks

All input devices stop working suddenly

Every now and then ALL input devices stop working,ths is not temporary - a forced shut down is needed
What happens is that I am happily working away when suddenly all input devices stop working with no warning, so the light goes off on my Wacom (Intuous 3) tablet, the keyboard and the apple trackpad are not responded to i.e. the cursor stays where it was on the screen prevously and I am left with the only option to restart by holding down the power button
any thoughts or similar experiences

If you don't already have a current backup, back up all data before doing anything else. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem. The backup is necessary on general principle, not because of anything suggested in this comment.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The procedure will help identify which such modifications you've installed, as well as some other aspects of the configuration that may be related to the problem.
Don’t be alarmed by the seeming complexity of these instructions — they’re easy to carry out. Here's a brief summary: In each of two steps, you copy a line of text from this web page into a window in another application. You wait about a minute. Then you paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is copy; paste; paste again. That's all there is to it. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken while booted in “normal” mode. If the system is now running in safe mode and is bootable in normal mode, reboot as usual.
Below are instructions to enter UNIX shell commands. They do nothing but produce human-readable output. However, you need to think carefully before running any program at the behest of a stranger on a public message board. If you question the safety of the procedure suggested here — which you should — search this site for other discussions in which it’s been followed without any report of ill effects. If you can't satisfy yourself that these instructions are safe, don't follow them.
The commands will line-wrap or scroll in your browser, but each one is really just a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. Step 1 should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
PB=/usr/libexec/PlistBuddy; PR () { [[ "$o" ]] && printf '\n%s:\n%s\n' "$1" "$o"; }; PF () { o=$($PB -c Print "$2" | awk -F'= ' \/$3'/{print $2}'); PR "$1"; }; PN () { [[ $o -eq 0 ]] || printf "\n%s: %s\n" "$1" $o; };{ system_profiler SPSoftwareDataType | sed '8!d;s/^ *//'; o=$(system_profiler SPDiagnosticsDataType | sed '5,6!d'); fgrep -q P <<< "$o" && o=; PR "POST"; o=$(( $(vm_stat | awk '/Pageo/{sub("\\.",""); print $2}')/256 )); [[ $o -gt 1024 ]] && printf "\nPageouts: %s MiB\n" $o; o=$(kextstat -kl | grep -v com\\.apple | cut -c53- | cut -d\< -f1); PR "Loaded extrinsic kernel extensions"; o=$(launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)|\.[0-9]+$/{print $3}'); PR "Loaded extrinsic user agents"; o=$(launchctl getenv DYLD_INSERT_LIBRARIES); PR "Inserted libraries"; o=$(crontab -l); PR "User cron tasks"; o=$(cat /e*/lau*); PR "Global launchd configuration"; o=$(cat ~/.lau*); PR "Per-user launchd configuration"; PF "Global login items" /L*/P*/loginw* Path; PF "Per-user login items" L*/P*/*loginit* Name; PF "Safari extensions" L*/Saf*/*/E*.plist Bundle | sed 's/\..*$//;s/-[1-9]$//'; o=$(find ~ $TMPDIR.. $ -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 $ | wc -l); PN "Restricted user files"; cd; o=$(find -L /S*/L*/E* {,/}L*/{A*d,Compon,Ex,In,Keyb,Mail/Bu,P*P,Qu,Scripti,Servi,Spo}* -type d -name Contents -prune | while read d; do ID=$($PB -c 'Print :CFBundleIdentifier' "$d/Info.plist"); ID=${ID:-No bundle ID}; egrep -qv "^com\.apple\.[^x]|Accusys|ArcMSR|ATTO|HDPro|HighPoint|driver\.stex|hp-fax|JMicron|microsoft\.MDI|print|SoftRAID" <<< $ID && printf '%s\n\t(%s)\n' "${d%/Contents}" "$ID"; done); PR "Extrinsic loadable bundles"; o=$(find /u*/{,*/}lib -type f -exec sh -c 'file -b "$1" | grep -qw shared && ! codesign -v "$1"' {} {} \; -print); PR "Unsigned shared libraries"; o=$(system_profiler SPFontsDataType | egrep "Valid: N|Duplicate: Y" | wc -l); PN "Font problems"; for d in {,/}L*/{La,Priv,Sta}*; do o=$(ls -A "$d"); PR "$d"; done; } 2> /dev/null | pbcopy; echo $'\nStep 1 done'
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
The command may take up to a few minutes to run, depending on how many files you have and the speed of the computer. Wait for the line "Step 1 done" to appear below what you entered. The output of the command will be automatically copied to the Clipboard. Paste into a reply to this message. No typing is involved in this step.
Step 2
Remember that you must be logged in as an administrator for this step. Do as in Step 1 with this line:
PR () { [[ "$o" ]] && printf '\n%s:\n%s\n' "$1" "$o"; }; { o=$(sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|calendarse|cups|dove|isc|ntp|post[fg]|x)/{print $3}'); PR "Loaded extrinsic daemons"; o=$(sudo defaults read com.apple.loginwindow LoginHook); PR "Login hook"; o=$(sudo crontab -l); PR "Root cron tasks"; o=$(syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail -n25 | awk '/:/{$4=""; print}'); PR "Log check"; } 2>&- | pbcopy; echo $'\nStep 2 done'
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: Step 2 might not produce any output, in which case the Clipboard will be empty.
You can then quit Terminal.
To prevent confusion, I'll repeat: When you type your password in the Terminal window, you won't see what you're typing.
Note: If you don’t have a login password, set one before taking Step 2. If that’s not possible, skip the step.
Important: If any personal information, such as your name or email address, appears in the output of these commands, anonymize it before posting. Usually that won't be necessary.
Remember, Steps 1 and 2 are all copy-and-paste — type only your password. Also remember to post the output.

Bluetooth mouse stops working when adding a printer: 10.10.2

Hi,
I'm using a MacBook Pro 2012 Retina, upgraded to 10.10.2. Since upgrading to 10.10.2 I have been unable to connect to my Canon MG6150 that is plugged into the USB port of the Time Capsule (3TB). Those problems will be detailed in a separate post.
I have tried deleting the printer and creating a new printer and when I click on the + and get the window to select a printer, the bluetooth mouse stops working - the message comes up to show "Connection Lost". I have to select the printer manually and only when I have returned to the main Printer window in Settings & Preferences does the mouse connection work again.
Weird. Between this and not being able to set up the scanning features again (that used to work), I'm feeling underwhelmed...

sounds like an IRQ conflict. See if disabling plug and play in the bios solves it. Arch's kernel provides this already.

My Bluetooth has stopped working

Please help.
My bluetooth has stopped working, I have the bluetooth icon in the menu bar but when ever I go to turn it on it stays off. I have looked at my bluetooth preferences to try and pair my phone to it, when it prompts me to turn on bluetooth it still stays off and grayed out in the menu bar.
Is there a way that I can check if my bluetooth is still functioning on my macbook?
Thanks

Bluetooth suddenly stops working?

Has anyone had the issue where the factory Bluetooth suddenly stops working on the PowerMac G5?
My G5 (Dual 2 gig) has been working like a champ, and suddenly during use or when it is attempting to sleep, will seem to "lose" the computer. The computer in System Preferences can still see the bluetooth power levels, they appear to be paired, but moving the mouse and/or keyboard does nothing.
A reboot seems to be the only thing that clears it. The only recent addition was a wired USB camera cradle, and the problem did seem to start around then, but I don't know why that would impact Bluetooth. Any ideas?

The problem turned out to be a combination of RF and a hardware problem.

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>

IPad2 Bluetooth just stopped working !?!!! Help !!!!

Hi,
Something really wierd just happened. I have been searching for simila issues but have founf nothing else in the forums.
I have an iPad2 which was working with a paired keyboard (apple 2 AA battery powered bluetooth wireless keyboard). all was good, and this has worked for quite a while, until suddenly when I went to enter data the screen keyboard appeared and the bluetooth keyboard no longer worked.
- Thought it might be the keyboard so checked it paired with my iPhone, it did and and all was well.
- unpaired from iPhone and tried to pair again with iPad, keyboard not discovered !
- Did the usual bluetooth on/bluetooth off, power on/ power off, resets, reboots etc .... issue remains
note the iPad 2 bluetooth is stuck saying "Searching..." doesn't discover any bluetooth devices and basically is bricked !
WiFi works, everything else seems to be OK
Has anyone else seen this ?
Regards,
Mark

I have a similar problem, iPad 2 dosen't see any bluetooth devices. So I've tested the bluetooth keyboard with other iPads and it works fine. The weird thing is that if I take a completely different iPad and restore it with this user's data and apps the bluetooth on that iPad stops working. And once I wipe that user's profile from the iPad bluetooth starts working again. Even if I reset all settings it won't pair with any bluetooth devices, it just sits there searching. Is there any apps or anything that can interfere with how bluetooth works?
