Bluetooth not working and not appearing in the devices manager

My bluetooth suddenly is not working anymore and i can't see it in the device manager.
I tried to reinstall the drivers but the problem persist. I have one strange USB problem happening too at the device manager, and it just appeared after the bluetooth problem. How can I solve it? One image of the problem is attached!

Try to update the IRST driver, and see if it helps the problem.

Devices enroll but do not appear in the Devices section in Profile Manager

Hi,
I am able to download and install the enrollment file, and when I check the devices enrolled by a user I can see the device attached to that users name, but when I click the link arrow next to the device name or go into the devices page, the device doesn't appear. Anyone have a solution for this? It's preventing me from managing any devices as it appears as if they are not there. I also notice that the Enroll button is still there in "my devices" after successful enrollment.
Thanks,
David.

Just in case anyone else get's this issue I managed to fix it by first enrolling the device then entering a place holder for the device in profile manager using that devices serial number. Then it seems to recognise the device

TS1538 My computer and itunes won't recognise my ipod. It's not coming up anywhere, not even in the device manager as a camera or whatever the troubleshooting said it might say. Plugging it in with the USB cable just charges the device.

Ipod is not connecting to itunes. It doesn't show up in itunes, 'my computer' or the device manager and plugging in the cord just charges the device.

Hey, first off, i'd like to say i'm not extremely technical - but i'll try and keep up. i'm having more or less the same problem as JasperMack, only, iTunes is recognizing it as my brother's iPod - Not mine. I've searched through the device manager and i got nothing that will recognize it there. My iPod DOES however charge, it almost takes on the roll of my brother's - only problem is when i got to sync it, it says "no device avalible" or whatever. I got this iPod 2nd-Hand (probably a bad idea) and i have no idea what to do. This is the 1st time i've attempted to to plug it into my computer and it's already taking a flying leap into hte zone of "not working" anything???

Why do all websites visited not appear in the Permissions Manager list?

Some websites I visit (e.g., play.com) do not appear in the list on the left of Permissions Manager. However when I click 'Manage cookies' they do appear, with a list of cookies set. Is this due to some setting I don't know about? How can I stop it happening? OS is Windows 7.

you can also access the permissions of a page when you're visiting it by right-clicking & going to ''view page info > permissions''.

HT4623 My phone does not appear in the devices

My phone doesnot appear in the devices. I have the updated iTunes on my computer.

Try reinstalling iTunes. Make sure you are downloading the correct 32 bit or 64 bit version depending on your operating system.
If this doesnt work, try using a different USB slot, perhaps the one your using is faulty? Or perhaps a different cord.

MY DVD Drive is not recognized by the Device Manager

Hi,
I own a Presario 6608AU version notebook.

New ATA channel with an exclamation point appear in the device manager at each start (when no new device has been installed)

Good morning,
My desktop, (Win7 64, AMD cpu/ Gigabyte mother board) , started to generate strange problems such as my laser usb printer not reachable even after disinstal/reinstall.
I took a look in the device manager, and found 2 ATA channel with an exclamation point, "drivers not found'. I also found a USB universal controller with the same exclamation point and the same error.
I changed nothing in terms of Bios since the machine was built (AHCI, Raid not active). The main drive is a SSD on primary SATA port, classic drive on the second port.
I deleted the 3 items, the printer started to work again. They reappeared after the next reboot.
Weird thing: it looks like the problems appeared after connecting/disconnecting a Nikon camera to one of the usb port (identified as a mass storage device).
I ran multiple scans (root) in case a virus would have generated the problem, negative.
Last point (can't tell if it's related or not), my browsers started crashing randomly.
Thank you

Microphone doesn't appear in the Device Manager in Windows 7

I'm using Windows 7 64 Bit OS on my MacBook Pro, clean installation, not based on Bootcamp, no MAC OS installed (required by our company otherwise I can't access corp network). Now my problem is that the speakers are working properly, but I can't use the internal microphone as it doesn't show up in the device manager. Cirrus Logic CS4206A (AB28) latest driver is installed. External headset with microphone works fine. Any help welcome, thanks in advance.

I disabled my microphone in Bootcamp Win7 Ultimate 64B and now it is completly gone. I used the Windows support CD I made and re-installed the 64B Cirrius drivers but the microphone is no where to be found also missing in device manager as well as Control Panel Audio.
Help.

No items appear in the Device Manager

I can't get my laptop to detect any devices when I plug them in, I check the "Device Manager" and its empty. I checked for corrupt files as one article suggested and it looks like that's not the problem. I don't have any antivirus install either.
Any suggestions? Please help, I was told that if I don't fix the problem soon, the laptop soon won't boot.

Is there any changes before this issue happen?
I suspected this is registry issue
This step should be helpfull

Hi. I have 3 different casemate hard cases and i have been experiencing same problem.

When I click on Firefox, it won't open... the icon flashes as if opening but no browser window opens. It also does not appear in the task manager

I click on the icon and it flashes as if opening.... no browser window appears.... I check the task manager to see if it is open but not displayed... nothing in the task manager..
So I uninstalled it leaving my preferences, and reinstalled it but it does the same thing. This time when I went to uninstall it again wiping the preferences away (in case it is those that is causing the problem) the uninstall program said that I had to close firefox first... but it isn't showing up as open in the task manager....
Final though... the last few weeks I have had a page pop up to advertise a need to update this or that, a need to click on this or that... obviously some kind of bug/virus.... help me get firefox going again...

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.
Do a malware check with some malware scanning programs on the Windows computer. 
Please scan with all programs because each program detects different malware. 
All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.

With firefox not running, I cannot upgrade as my computer thinks it is still running. Firefox.exe does not appear in the task manager.

I seem to be able to start Firefox only once after I reboot my computer. After that it will not start. I tried upgrading the software using Internet Explorer to get the upgrade file. The installation failed when the computer said I needed to close Firefox to install the upgrade. The task manager didn't show firefox on the list as one of the processes and it wasn't running anywhere on my machine.

Jim Harris:
Hanging at exit is most frequently caused by an Extension or a Plugin.
'''Kill Application'''
In Task Manager, does firefox.exe show in the '''Processes''' tab?
See: [http://kb.mozillazine.org/Kill_application Kill Application]
'''Causes and solutions for Firefox hanging at exit:'''
[[Firefox hangs]]
[http://kb.mozillazine.org/Firefox_hangs#Hang_at_exit Firefox hangs at exit]
[[Firefox is already running but is not responding]]
'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes '''before''' starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
See:
'''[[Troubleshooting extensions and themes]]'''
'''[[Troubleshooting plugins]]'''
'''[[Basic Troubleshooting]]'''
If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it by enabling '''one at a time''' until the problem reappears. '''You MUST close and restart Firefox after EACH change''' via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.
