Multiple Bluetooth Devices In Device Manager, One Device Installed
Sep 30, 2008
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.

Can not get my HP 7400 scanner to work after upgrading to Vista Ultimate 32 bit. Not the hardware - works fine under XP pro using same hardware configuration. Did a clean install, installed motherboard BIOS updates, scanner BIOS updates, Vista updates and the correct driver from HP. The scanner installed and Device Manager says device is working properly. When I try to scan, scanner initializes, starts to scan then locks up. Then can no longer be seen. ASUS M2N-E motherboard with AMD dual core. Other than that Vista works OK with the rest of my system

I know this is a repetitive topic, but I can not seem to figure this one out. It is a HP Laptop DV9815nr. I do not know much about it as it is not mine, but the problem is the audio was cutting out and now there is nothing. The computer is not recognizing any type of audio device installed. Even in Device Manager, there is no option for Sound, game and controllers. I have tried downloading the driver and installing, but no luck there.

When I hover over the sound icon, it said "No Audio Output Device Installed". I have had this laptop for over 2 years and this is the first time this has happened.I have been reading several posts and many of them say to go to the "Sound, Video & Game controllers" tab in the Device Manager. However, that tab doesn't exist for me. I even clicked "Show Hidden Devices".

I had been running Vista Ultimate x64 for a few months and recently found that I can only use the original USB mouse?! Installation of any USB mouse would show a new "USB Human Interface Device" in Device Manager but it just won't work. Installation of the very same model of my original mouse didn't work neither. So basically I am stick with the current mouse?

I have a Dell XPS M1330 laptop with Dell TrueMobile 355 Bluetooth. Recently my computer has had problems with detecting any Bluetooth device I've tried to connect. I was wondering if anyone knew what I should do. The only thing I've tried is uninstalling and reinstalling all the drivers

I have a HP Compaq 6715b notebook with Vista Business, the OS preinstalled from HP. For some time ago I connected my Sony Ericsson mobile to the PC as a new Bluetooth device. During the installation, I was prompted to install missing drivers for devices named "Bluetooth Peripheral Device". I never found any drivers, and finally I ignored it. The installation was successful as far as I can see, I have never noticed special problems. However, when I look into My Computer > Device Manager, there is a listing under Other Devices, 2 "Bluetooth Peripheral Device" and 2 "Unknown Device", in total 4 devices, all missing drivers. A quick look at Google tells me that there are many others with HP machines in the same situation, HP obviously does not install these drivers for some reason. I contacted HP support in Scandinavia, but they didn't know anything about Bluetooth Peripheral Device. I see further in Device Manager that there is a HP Integrated Bluetooth module (together with Microsoft Bluetooth Enumerator), maybe these are substitute for the "Bluetooth Peripheral Device"? Can anybody tell me more about this? Do these missing drivers exist, are they important, or should they just be ignored?

Ok so for a few days now my audio has not been working, I use it quite frequently with itunes and dvds etc but not ever very loudly. I've been on my laptop's website and have tried everything they've suggested except for system restore, and nothing has worked. I've made sure my computer is completely updated, I have downloaded the newest update of the audio driver from the website, and still no luck. In Device Manager it says everything is working, I have no error signs either. The mixer picks up the sounds when I test for it, I just can't hear it! It doesn't work with headphones either, although when I plug my headphones in and pull the socket in and out a little bit I can hear crackles in the headphones.

I installed a PCI card for a firewire cable and also installed the software disk containing the drivers. It would not recognize the new device and now, my Device Manager is blank, sound is not working, etc.

I just got a new computer with 64-bit Vista Home Premium, and am having some issues with devices. When I connected my Lexmark X6100 printer, Vista recognized it and even took me to the website to download drivers, which I then installed. when I bring up Printers in Control Panel, the Lexmark is not listed. The X6100 also includes a scanner which again Vista found, but it directed me to the same download as for the printer (not surprising). There is an entry for the Lexmark X6100 in my Start Menu, but the only option there is to uninstall the software.
My old computer ran XP Pro and the Lexmark worked perfectly there. There was even an icon in the system tray that appeared at startup. A second issue has arisen with my webcam, a Logitech Quickcam Pro 5000, which Vista also recognized, and there was a prompt which looked as though it was from the Logitech driver asking for a disk which I did not provide, because I didn't think it was necessary. The cam also worked well under XP without any additional software installation.
Vista's Device Manager reports that both devices are working properly, but I am unable to access either of them. I also installed a program called PDF Factory which I used as my default printer on my old computer, and it's working just fine - and it shows up in my Printer panel.

On an HP m8120n, I had HP replace the DVD drive that came installed (didn't do DVD-DL). New DVD drive worked fine for 2 months, watching movies, burning CD's and DVD's, but now can't watch commercial (legit bought or rented) DVD's. Quick search of these forums I found this link - which I d/led and ran. It stated there might be a problem with the ASPI layer. Quick search of that turned up something about turning DMA off (or on, forgot what) and that I needed to go to Device Manager and find the IDE ATA ATAPI tree. Here's the problem, I don't have a +tree that says IDE ATA ATAPI. Should I?

Suddenly I can't access Device Manager via Control Panel/System. When I click on the link that should open the Device Manager, nothing at all happens. The link has been deactivated? I can still start the device mgr by running the file directly from Win32.

I am having an issue with the hd 4350 card. I read on another post that re-installing windows solved the problem however I have an on-board video unlike the said poster. Problem: Device manager only lists the on-board display adapter, not the 4350. Heres the funny thing, When I run my diag program (pasted below) the 4350 is actually listed. I did RMA the first one I received and was disappointed to see the replacement doing the same thing. Anyway the reason for this post is to find any other possible solutions before I go an re-install windows. Wiping my puter is really the last resort for me but at this point RMA is no longer the issue.

My Dell XPS M1530 Vista SP2 all of sudden had the icon for volume/sound disabled. When I did some investigating;
- The machine seems to be working fine but it appear to be very slow, backing up my machine took for ever, sometimes it see my external disk and other times it didn't
- I received a message stating that I need to check windows latest update and I tried to install an important SP2 but it failed
- Device Manager is showing no device, it's looks completely empty
- called Dell support, they were unable to figure it out, even though I have 3 year warranty they are saying they will have to charge me for s/w support, which was never a problem before.
- I tried to do restore but it states there is no restore points
- I tried to see if I could start the Plug & Play but it gives error
- I tried to install the Audio driver from the Dell Disk and that gives errors

I installed a 2nd hard drive and Vista found its drivers. The drive is showing up in Device Manager but I can't figure out how to access it. No letter is assigned to it. If I look under 'computer', C is my original drive, D is the recovery drive & E is the DVD/CD drive. No other drives are listed. Device Manager reports the drive is working properly.

1.) I don't know if it's important, but "npkcrypt" is apparently either missing or damaged, according to Device Manager..... I imagine there's no file that's missing that can be GOOD, but I figured I'd ask if there's a way to fix that, or it could be relevant to problem number 2.....
2.) Lately when I shut my computer down, 50% of the time if not more often it takes forever to shut down, doesn't shut down, or will but claims that "windows has suffered from an unexpected shutdown"..... even though it shut down because I TOLD IT TO. When it comes back on it says I suffered a BlueScreen, which I've only actually SEEN happen one or two times, but it claims it happens almost every time those other problems occur.
3.) Another thing I would like some aid with, if possible.... there are programs I want to prevent from running when I start my computr, but when I go in to stop them, it won't let me, stating that the scan on them leaves them "unidentified," so I can't make them NOT start along with my PC. Only Microsoft programs are capable of being stopped.... any way around that?
4.) I think the problems with 2 may be related to some downloading done on my part recently, but I have McAffee AND all my windows stuff on maximum security.... not a peep from ANY of them.
5.) When the start-up/shut-down issues started happening a few days ago it also said my CD-ROM driver was messed up, and I thought that was the ACTUAL problem, but when I fixed that, it still didn't stop the Bluescreen issues from occurring. I don't know what to do to fix ANY of this, but if someone does, or could AT LEAST explain what the hell it all means, that would be GREAT.

My first post here and unfortunately I'm posting because I've stumbled right into some technical issues with this fresh desktop build.
First off, comp specs so we know what we're dealing with:
MOBO: ECS P55H-A Black Edition
CPU: Intel i7 860
PSU: BFG 800W
Graphics Card: POWERCOLOR AX4870 (two of them)
OS: Vista Home Premium x64
I have everything hooked up properly and can verify both PCI-E slots are working and both video cards are working as I've tested them all separately. I'm using the latest CCC and drivers available.
I initially hooked up just one card, then loaded Windows and it detected it just fine, so I installed the drivers. Everything was just fine, so I shut down and installed the second GPU and hooked it up and attached both Crossfire bridges to the two cards. Nothing I have done since will cause the card to show up. I tried removing the bridges and rebooting also to no avail.

I just bought an EVGA nForce 730i mobo with onboard GeForce 9300 graphics card. I installed vista ultimate 32 bit and the first thing I did was install all the drivers from the disk that came with the motherboard. For some reason I can't find my display adapter in my device manager list and I don't think the driver from the mobo disk is installing properly but I can't check that because I don't see the adapter in the device manager list. Any idea on how I can fix this?

I wanted to attach a TomTom Go 720T to my Windows Vista Home Premium notebook. Unfortunately Vista does not install the necessary USB mass storage driver and for that does not recognize the device. In device manager this is shown as "unknown device". I'm not able to use it and TomTom support told me that only the basic USB mass storage driver is needed and that is produced by the OS vendor.

I have an HP dv9208nr laptop which has worked perfectly for me until recently. A few days ago after closing the computer and opening it back up i noticed that the wireless wasn't working. Obviously i checked the switch and the switch was on but the LED was orange indicating that wireless connectivity was turned off. I tried restarting and no luck; after a few other simple fixes didn't work; i went to the device manager and noticed that the wireless card wasn't in the list as it should have been. I tried updating the drivers; nothing. HP techs sent me a link to a service manual and instructed me to reseat the card manually, reset the BIOS, and reinstall the drivers. It didn't work. the next day the computer had found the card as new hardware and installed it. it worked fine for a day; then the same thing happened again.

Are SATA and SATA2 like what USB1.1 and USB2.0 used to be? I mean does the motherboard have to support SATA2 even though you already have SATA connectors on the motherboard? If not and one wanted to install a SATA2 harddrive on their computer, would you have to do a motherboard BIOS update? Or would you have to by a seperate card for SATA2, like I had to buy a seperate USB2.0 card with my old computer? And my last question: Is there a setting in say Device Manager to tell if your motherboard does support SATA2?

I am trying bring-up a new SATA Hard Drive through PCIe to SATA AHCI Host Card. We find that Vista recognized the AHCI Controller and it shows up in the Device Manager. It successfully allocates the memory and IRQ, and says that the Device is working properly. But the HDD is not recognized. When we look at the PCIe analyser, we see that the OS is continuously polling the AHCI Interrupt Status Register (Addr: 0x08). This register is reading 0x0 all the time.

The Microsoft 6to4 adapter showed in the device manager that it was not working properly. If you look at yours it may show the same. I think I disabled it trying to update it. This was before I found this short sweet article from Microsoft. Does anyone know if I will experience problems in the future when this new technology gets more prevalent? If so, how do I get it back. I followed the instructions that a vista pro gave me to fix this problem and it shows in the reliability monitor that it was installed...but it is not showing int he device manager. Would it be installed but not show on the device manager?

I have a friend who asked me to look at his HPA1737C desktop running Vista Home Premium tonight and most, if not all of his System32 processes, are no longer accessible. System Restore, Device Manager, MSCONFIG. etc cannot be opened and seemingly also anything System32 file related. Even the Volume icon in Taskbar has a Red X on it. I placed computer in SafeMode and selected Restore To Last Known Good Configuration and it had no affect on restoring. I could access the internet with IE7 and he can send email with no problems. Cannot uninstall or install any applications. He did install some Windows Updates KB867812, KB959772, KB960225, and KB958690 a few days back, but I see nothing in the Vista Newsgroup that would make these possibly related to his problem. Has Norton AV with latest definitions and full scan indicates no problems. I have set up a few Vista systems, but my expertise is XP related.

I am experiencing a Catch 22 problem with the NVidia GeForce Go 7300 Drive that was pre-installed as part of my system. I have experienced a number of problems with this unit, all reported to Microsoft Windows for solution. Their response; Attachment 7159
I have been through all the recommended troubleshooting steps, without success. NVidia don't want to know because Acer installed it, Acer just don't want to know, and Windows just keep passing the buck. The Device Manager washes its hands on the issue with; Attachment 7160
So on one hand I'm being advised that I have a problem, and that it has been reported [MS Windows], then the answer is given that there is no solution [MS Windows] but if you'd like to check it out, here are four options [each in turn involving NVidia, Acer and MS Windows]..And oh! By the way, you won't find your solution here, either....because nobody in the list will accept any responsibility to help in any way to resolve the problem......Ya!Ya!Ya!....."Catch 22". I think that this Version is Force Ware Vista 97.55, as it shows up in my System Information as 'system32drivers vlddmkm.sys(7.15.10.9755, 4.24MB - 18/01/07.
