multiple bluetooth devices in device manager, but only one device installed?????

Q: multiple bluetooth devices in device manager, but only one device installed?????

i have installed the correct driver for this belkin bluetooth usb dongle model: F8T012XX1

but in device manager, it has the belkin device and microsoft bluetooth enumerator, which is great. but when u get further down the list. it has a tab named "other devices" and then a subtab with "bluetooth peripheral device" which has an exclemation mark on it.

i have searched for driver software using the update service but it cant find no update.

i have looked for the name of the manufacturer but found nothing.

i then disabled the unknown device, and sent a picture to my mobile phone. which confirmed that it was not the belkin bluetooth device. so i uninstalled the unknown device, restarted the computer. then when i logged in, it said that it had found a new device and wanted me to find the CD that came with it..

i would be greatful if any1 could help me on this..

thanks in advance

Preferred Solution: multiple bluetooth devices in device manager, but only one device installed?????

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

What type of keyboard have you got?
Have you got any remote control devices around.
Have you got a headset for your phone.
Have you got anything that may be bluetooth that you dont know about (headphones etc).
Have you had a look at ghost devices on the tutorials;

I'm trying to fix an hp pavillion dv6704nr laptop running windows vista home premium. It has the little red x on the speaker in the lower right hand corner. The owner said it has been there for some months. I have tried downloading the current audio drivers for the computer but every time I try to install the driver, I get an error that says the device couldn't be found.

The first time i restarted the computer, after the driver installation failed, the audio came back and worked fine, until I had to restart the computer. Now I keep getting the same error and nothing i have found so far online has helped.

There are no yellow triangles in the device manager and the device list isn't showing the category for "sound, video and gaming etc." at all.

Please help. I did a search but the other threads didn't solve this problem for me.
Thanks in advance.

A:No audio device installed error and devices wont show in Device Manager

I see three different audio driver packages at http://h10025.www1.hp.com/ewfrf/wc/softwar...ct=3646926#N661.You need to find the right one to install. If you install one and the system doesn't work properly...please uninstall it before trying the next one.Installing the wrong one won't do anything harmful to your system...it just won't do any good to leave it installed.Louis

Whenever I connect a bluetooth device to my PC (such as my phone) I always get this list of peripheral devices with yellow exclamation signs (see attached image).

I have tried right-clicking on them and choosing to update each one, but that never works. I have also tried deleting/disabling them and they always come back.

Any advice on how to fix this would be appreciated.

In Device Manager I have a category 'Other devices' with two Unknown device under it.
I have a ASUS A8N32-SLI Deluxe Socket 939 Mother Board. (in case anyone has the same and thinks they can help) This is my second install of win 7. The first install I had troubles with win 7 and my realtek sound card; as well as these two unknown devices. I was able to fix the realtek problem on the first install, but not the unknown devices.

On this install win 7 had no problems with the MB's built in Realtek sound chip. Nice to know Microsoft is busy working on these things. :-) <~ brown nosing. Last install after solving so many little problems on my own I decided to tackle these Unknown devices. Up to that point all I'd done is right click on them and tell win 7 to update the drivers.
First I downloaded any new drivers and software from Asus for vista and this mother board. Then right clicked on them and chose update driver and pointed to each (unzipped) download in succession. Then I did the same using the CD that came with my MB. Then I just started running the programs in the hopes that one of them would do it.
Afterwards I still had the two Yellow ! unknown Devices and what seemed to me a very sluggish computer. So I've done a fresh install and now am looking to find out what these items are and get the drivers installed in a less hap hazard way.
Too that end I booted up a fresh install of XP on the same comp to compare the two device managers. The two compare until th... Read more

Hello, everyone.

I noticed a problem in my keyboard recently, but i'm not sure if it's really on the keyboard, and might be in the windows or software related. The problem is that the keyboard randomly starts freezing, it's hard to explain with words, basically the keys do not operate in the way they should, i notice this problem usually when i'm playing games, where my "W" that should move my character forward continuously. does not, instead of doing what it's supposed to do my character goes forward while freezing along the way. When i unplug, and plug it again on the USB port, even on a different one, the keybord start to operate normally again, but randomly shows this problem from time to time. It's not only with the "W" key, was just an example.

I noticed something yesterday, i don't if it's supposed to be that way, and i can't find any information about, it's that on device manager it shows multiple devices on the keyboard section, when the device is connected, as it shows in the image below:

One more thing, is all of them looks like the same thing, but i'm not sure if they really are, image below:

If i uninstall all of them, except that one that i marked with purple, he is the 4th one in the first image, the keyboard still operates, i'm not sure if the problem is fixed by that, cause it does not happen all the time.

Now that i described everything, i want to ask 2 questions:

I have a Toshiba laptop, model L505-ES5018. I had Windows 7 Home Premium 64 bit installed on here, but decided to reformat my hard drive using Windows 7 Ultimate 64 bit. After the reformat was finished, I ran Windows Update and it found several items to download and install for me. I noticed that it also found optional items to download and install for me, so after all the important updates installed, I ran the optional updates. After all of this installed, I checked Device Manager to see if there were any errors and I found nothing. I assumed everything was fine. I decided to check Devices and Printers and under my laptop icon, there was a yellow icon with an exclamation point on it. I decided to run the troubleshooting option when I right-clicked the icon....it gave me a solution to download a Toshiba password utility program, so I did that and nothing happened, even after restart. Same icon appeared. When I clicked on the icon a second time, I noticed that the model of my computer at the bottom of this window, changed from L505 to TIAS. I have no idea what this is. I decided to do another reformat on my hard drive. This time, I ignored the optional updates. I checked Devices and Printers again, the same icon appeared but the model of my computer said L505, like it should. There is something in the optional updates that is changing this. Could it be the Intel chipset driver that the optional update is pushing? I'm not sure. I went back to Device Manager, th... Read more

Recently I tried to pair a bluetooth mouse with my T450s and... failed. Perplexingly the bluetooth device doesn't appear in device manager at all.I've reinstalled the intel bluetooth and wifi drivers multiple times.I've checked all drivers and bios are upto date.I've gone into the bios and enabled/disabled bluetooth to try and 'kick' it into life, all made no difference.I've even replaced the wifi card with an AC-8265 and experimented with swapping the antenna. Even after all that (with the current state being the antenna's the right way around and bluetooth enabled):There is no bluetooth device in window device manager.There is no 'unknown' or other device in device manager.The windows BT troubleshooter says:  "device does not have bluetooth"I've even tried booting up an ubuntu live cd and that can't find any bluetooth either. What am I missing?  Is there some other switch that would disable bluetooth?

I have two USB audio devices that I cannot seem to properly install drivers for.
Focusrite Scarlett 2i2 & KORG MicroKONTROL

I am in communication with both product tech support teams but so far they have not offered a successful solution. As the same issue is occurring with multiple devices I thought it might be an OS issue.
I run Win 7 Home Premium x64

The problem is as follows:

The product drivers install correctly without error. However, instead of showing up in the Device Manager in either USB Controllers or Sound Controllers they both show in Other Devices with a yellow exclamation mark.
I have tried the following fix from this site (USB Driver - General Fix for Problems) and this actually enabled me to access a portable HDD that wasn't working, but it didn't fix the issue for my 2 audio devices.
I have also tried right clicking on the devices in Other Devices, selecting Driver Update. I then find the correct drivers listed but when I hit install I get the following error message on both:
"Windows found driver software for your device but encountered an error while attempting to install it. One of the installers for this device cannot perform the installation at this time."

Any suggestions would be greatly appreciated.

I clean installed an ASUS Laptop Model a2500h, Windows XP Home edition SP3.

There are two drivers that I can't seem to locate. The Hardware ID's are as follows.


I know ASUS often has utility programs that show up as drivers, for example I had the ACPI\ATK0100 which was listed as an UNKNOWN DEVICE, and I installed that utility fine.

I am just not sure about the other two. I was told on another forum that it could be something to do with the sound drivers, but I suspect it is one of ASUS' little utility programs.

Windows 7 64 Bit, does not detect ANY network adapters. We installed windows in August and it has been fine, now for some reason it simply doesn't detect any adapters at all and does not display a Network Adapters heading in the device manager folder tree.

The hardware in question is an onboard LAN card on a ASUS Sabertooth X58 motherboard, the lan card is listed in the bios as a RTL8110SCLAN

I have checked to be sure that the device is enabled in the BIOS, as well as disabling other on board devices in case there was some kind of conflict. I also tried installing an add on LAN card and that card is not detected either. I have also reset the bios and removed the battery etc. I have tried reinstalling the chipset and other drivers and I have uninstalled windows updates that happened near the time the network adapter vanished.

Hi, and welcome to TSF.

Did you read this ?


You should not run ComboFix unless you are specifically asked to by a helper. Also, due to the power of this tool it is strongly advised that you do not attempt to act upon any of the information displayed by ComboFix without supervision from someone who has been properly trained. If you do so, it may lead to problems with the normal functionality of your computer.

Did you try to run the add new hardware wizard to see if it detects the card ?

That occurred with my ATI 9600 .All I did was delete both in device manager ,then reboot ,Cancel the auto-reinstallation by windows and use the Hardware Wizard to install your drivers.You choose the drivers you want installed from a fie or disk.
ATI websays you can also do this by using the Update driver tab in Device manager and and again force Windows to use your drivers.
There are 2 instances of My 9600 in device manager because it supports more than 1 Display(Digital,Analogue) It is probable the same for you.

My PC (Windows XP) has a problem -- in device manager, all of the imaging devices are in broken state. They are listed under imaging devices, but they have the dreaded yellow circle and question mark on them.

This began to be a problem only fairly recently, with my scanner. Can't scan; get an error message. This is true despite replacing my previous scanner.

In Device Manager, the properties screen for the scanner (as imaging device, it's a multi-purpose and is working fine as a copier and printer) says:

"Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Click troubleshoot etc."

I've been through the whole troubleshoot menu, with no results. Also been on the phone with HP tech and did the whole uninstall and reinstall thing (again) and it did no good. He told me it's a PC problem and I need to ask Dell about solving USB controller or BIOS issues.

Anyone have any idea what is going on inside my PC, and how I can go about fixing this? Thanks for reading and any advice.

The hardware in question is an onboard LAN card on a ASUS Sabertooth X58 motherboard, the lan card is listed in the bios as a RTL8110SCLAN

I have checked to be sure that the device is enabled in the BIOS, as well as disabling other on board devices in case there was some kind of conflict. I also tried installing an add on LAN card and that card is not detected either. I have also reset the bios and removed the battery etc. I have tried reinstalling the chipset and other drivers and I have uninstalled windows updates that happened near the time the network adapter vanished.

I used RKILL and ran ComboFix and Malwarebytes to clean up a few minor virus/spyware files. But that too has not helped.

This is my first post, but I have been a big fan for a long time you guys do great things.

Please help before I get any more grey hair.

Two of the four USB ports in my motherboard were not working properly. After plugging in any USB device it would recognize something was there, try to find a driver for it, but fail at doing so. These are plug and play devices I had never had problems with before. The device manager said the SM bus was not installed properly. I reinstalled the chipset driver and that fixed one of the USB ports; however, one is still not working. When I plug in any USB Device there is no audible ding, no "this device is not recognized" pop-up, and it isn't even showing up as 'unknown device' in the Device Manager. I'm not sure what could be wrong.

USB devices attempted:
1x Wired Mouse,
3x USB thumb drives
1x USB external hard drive

All devices are USB 2.0. The malfunctioning port is USB 2.0

My system:
Dell Inspiron 530s
Vista Home Premium x64
Motherboard Model 0RY007 (Socket 775)
Chipset Vendor Intel
Chipset Model P35/G33/G31
Chipset Revision A2
Southbridge Vendor Intel
Southbridge Model 82801IR (ICH9R)
Southbridge Revision 02

A:Device Manager will not respond nor will Cd-rom or usb devices

Open up a command prompt and type chkdsk /f /r[b/] it'll ask to restart so do so. Let it scan it should fix the MMC.EXE problem. As for the CD/ROM problem try opening the tray and blow out the inside with some compressed air and try again.

Since installing WP Pro SP2 on my laptop I've noticed 3 big yellow question marks in device manager for Network controller, SM Bus controller and Video controller. Despite these problems I can use the laptop as part of a network and video display seems OK until I try to video edit on Avid, which refuses to display moving video and flags up a warning about the video card.

I've been trying to re-install the driver for the ATI mobility radeon 9000 (64MB) adapter and get an error message that an INF file is missing and to try installing a standard VGA card. I know from other posts that this is a common problem. So far I've tried re-installing the SIS AGP driver followed by the ATI driver. No luck. I'm wondering if the fact that 3 devices have a problem since (I think) 'upgrading' to XP Pro SP2 from XP Home originally mean that the problem is to do with the OS.

Would it help to re-install or repair the OS assuming that this is the root of the problem?

I recently uninstalled a usb logitech headset and tried to put my old analog headset back in and it would not work. I then detected through view on device managers the invisable driver and also uninstalled it. It still will not work and when I do a driver detector scan I still show having

"USB Composite Device - Logitech USB Headset"
"USB Mass Storage Device - U3 Cruzer Micro"

They are under "Unplugged Devices".

I am using a trial version of Driver Detective to find these and don't want to buy it. So I was wondering if these two(for sure the first one) need to be uninstalled before I can hook up another headset how else could I go about uninstalling them? Or would another usb headset just install over them without a problem?

A:Device manager hidden devices.

If you have uninstalled all of those, and;

You don't have anything else from Logitech/Cruzer,
just go to Start->Run->Regedit
then Edit->Find->Find next

Delete everything.


No problem is so huge (in these small spheres) that it couldn't be solved with free software.

So never ever go buy anything unless you area SURE it is exactly what you need.

So, I'm really baffled as to how to fix this problem. I've scanned for viruses and spyware, came up with pretty much nothing. I've tried resetting tcp/ip and winsock (netsh stuff). I've tried sfc /scannow. I've tried uninstalling each device, but they just stay there. Any ideas? Is there any way to do a repair install to vista like you could with XP?

under Probe Devices I found Radeon Probe Device
Funny thing the drives is from ChrisW
I have the latest Omega drivers set and wonder if this wa installed or is this a default device for the Radeon or has it been installed without my knowing?
I have never seen this Probe Device in Device manager before but I'm still new to the world of ATi.
What the hack is it?

A:Device manager/Probe Devices

It is part of RadClocker. It's probably part of the Omega drivers, as mentioned here...
