Q: Unknown device in device manager after Bios default settings are


Sorry that last word didn't get in the subject line.


These two values are:
My bios info

So should I do this:

ASUSTeK Computer Inc.-Forum- driver missing
When I download that zip file from under "Install the Bluetooth driver:" it has so many files to choose from.... I don't know what to do?

I've also found out that I need to disable "boot from network" or "boot from lan" in bios to get rid of this unkown device issue?

Preferred Solution: Unknown device in device manager after Bios default settings are

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.)

A: Unknown device in device manager after Bios default settings are

Well it might be a good idea to look at the following tutorial:

Device Manager - Finding Unknown Devices

Use the link in Step 7

Also I tend to find this tool useful:

Download Tweaking.com - Hardware Identify Portable - MajorGeeks

Right click on each result in the list for more options.

Edit: On my machine a similarly named device appears to be a webcam.

In the list USB Composite Device doesn't mean much but matching the ID seems to indicate that it's the webcam.

My 7270 latitude touch screen stopped working shortly after first use (after win update worked again but for a short time).
All drivers are up to date.
In device manager a USB device shows as unknown (yellow warning triangle), otherwise there are no indications to the source of the problem.  There is no other touch screen device showing in device manager. 
How do I perminently solve this?

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

Hi everybody.

I just bought myself a Powercolor Radeon HD 4890 yesterday. After installing the card and the required drivers everything works like a charm. However, every time I start up my PC I get a message saying that a new device has been found on my system. On checking Device Manager I found an "Unknown device" entry under "Other devices".

I'm attaching a screenshot of Device Manager.

Are there any drivers I'm missing? It only happened after removing my old card (after uninstalling all its drivers) and installing the Radeon.

Any help is greatly appreciated.


A:Unknown Device In Device Manager After Installing Radeon HD 4890

I have a Powercolor Radeon HD 4890 (I also have a Gigabyte 4890 and XFX 4890 in two other PCs). I think you need to install the latest ATI Catalyst Suite. You may have installed the driver only package. Anyway, I think it has to do with the HDMI capabilities of the card. High def sound is built into the card (the HD part of the card name) and the HD sound driver is part of the Catalyst Suite. When you use an HDMI cable to an appropriate display, HD sound is also transmitted through the same cable from the Radeon graphics card.

Of course, be sure to install .NET Framework 2.0 as it is required before you can install the full Catalyst Suite. The HD sound driver won't install without it. At least I had trouble before I installed .NET 3.5. I went to Windows Update and installed .NET Framework 3.5. 2.0 is included in that update and 2.0 wasn't available separately.

How do i figure out what driver or even component windows wants software for when in the device manager under other devices it lists an unknown device and windows update cannot find anything.

Oh and is it appropriate for me to use this topic to ask another question regarding explorer.exe as while i am inside a folder i delete (by choosing delete from the context menu in the tree view) while inside that folder on this particular laptop PC explorer. always crashes, collect information, sends it and restarts explorer. I have not experienced this problem on any other pc running any version of windows 7, oh and the same happened with build 7264 x32 and the current install of build 7600 x64.

I recently put together a new computer, and in the process of of installing the USB 3.0 connector from the front of my GX500 case, I either bent numerous pins on the motherboard USB 3.0 header or the motherboard shipped that way and I inadvertently made matters worse. Anyway, that header on the motherboard is without a doubt unusable.
Since I don't really need the USB 3.0 functionality, I bought a USB 3.0 -> 2.0 adapter cable, connected one end to the connector on the front of the case and the other end into the USB 2.0/1.1 header on the motherboard. Unfortunately, when Windows 7 boots and I plug a device into the front ports of the case, Windows detects the front USB ports as "Unknown Device" within Device Manager yet says the driver is successfully installed. I've already downloaded the most current Intel chipset drivers for my motherboard, deleted and reinstalled all USB drivers, and all rear USB connections are working perfectly fine - it's just the two front ports that are connected from the case to the USB 2.0/1.1 ports via the adapter cable.  I've tried both USB 2.0/1.1 headers on the motherboard, and I've tried plugging in several devices to the front USB ports, and this problem still persists.
I've ensured the connection inside the case is solid, yet I cannot get Windows to recognize the front USB ports.  However, I have confirmed that power is being sent to the front ports because it charges my phone when I connect it to the front USB ports via m... Read more

Hello everyone, I hope you could give me some clue that may have caused the appearance of an unknown device. All information here : An unknown device appears

First, That was solved by uninstalling and rebooting, did not appear anymore. But as I said in the previous topic, that solution does not leave me entirely peaceful.
Since when searching for information on the issue, some say it may be a virus. But also by the HWMonitor. I prefer it was caused by HWMonitor instead of a virus.

Can give me a hand to remove my doubts about whether it was caused by a virus or not.

I scanned all the PC with ESET 6 and nothing.

Thank you for your time and help

Recently installed vista ultimate x64 fresh on new hd. I have been using the same copy on my older hd for 8 months.

As far as i'm aware i've installed all newest drivers for hardware.

There are two 'other devices' for which no drivers are installed. One I'm pretty certain is the gameport on my audigy 2 zs platinum pro [location = pci bus 2], which isn't supported in vista. the other one is a mystery [location = 'on Msoft ACPI-Compliant System].

I don't care about the gameport but i'd like to get to the bottom of the second device. The thing is the only thing that makes any sense to me in properties/details is in 'siblings' - it looks exactly like the description in the same properties/details for my cpu [athlon 64 x2 6000+] for which there are already 2 instances in 'processors'.



Could this unknown device have something to do with the cpu and might the fact it's unknown be affecting the computer performance?

I can give further info if required. I've no idea what might be needed!

I have a portable hard drive that i attach to my computer via USB.
It has worked fine so far but now when i plug it in the only response i get a message saying "USB device not recognized, one of the devices attached to this computer has malfunctioned....." and under Device Manager in Universal Serial Bus Controller Ican see not 1 but 2 Unknown Devices.

If I uninstall them both, unplug the hard drive from the usb port and do a Scan For Hardware Changes then I will get the message "Unkown Device. Device Driver Software installed successfully" and one unknown device will reappear in the Universal Serial Bus Controller.
Now I wonder: what device is that?? Clicking on properties doesn't really help

Plugging in the usb hard drive will bring again the error message "USB device not recognized....." then "Unknown device. Device driver software installed successfully" and the unknown devices number in Device manager back to 2.

The usb hard drive works fine on other computers so that is not the problem

Don't know if I have been very clear in describing the problem but any help would be appreciated.

I recently decided to to a clean install of Windows 7 7127 RC x64. I have been running Windows 7 x86 because even though I have x64 processors, my laptop came with Vista Ultimate x86 installed on it.

After reading about the differences between x86 and x64 systems and the fact that I have 4GB of memory that only came up as 3GB under x86 I thought I would experiment with Windows 7 x64.

My only problem so far is one unknown device under device manger. I originally had three unknown devices but the first two were based on my Nforce PCI system devices which I finally found here:

nforce Vista driver in Others drivers - Windows Vista Downloads

These are the drivers that worked for my AMD based Nforce system :

Nforce Vista drivers downloads - NVIDIA nForce Driver 15.23 WHQL for WinVista64 Vista driver download - Windows Vista Downloads

After installing the drivers I still have that one unknown device listed. I tried to run DriverMax but it only supports Vista x86 not x64. I also tried PC Wizard and a program called "Unknown Devices" that just tells me I have one unknown device...No Duh!!

I tried to identify the device by PCI vendor ID but it doesn't show one. Since the laptop came with everything pre-installed I have no idea what it can be.

These are the only things I can find to identify it.

I just put in a new Motherboard. An ASUS K8V-MX. It's a Socket 754 with a Athlon 64 processor, an Nvidia video card, 256 MB, A Creative Labs Audigy SE sound card and 2GB's of Kingston memory. I am runnning Windows XP Pro x64 on it.

I just loaded Windows yesterday and I like to get all of my drivers and updates installed first. I also usually check in Device Manager to see if there is ever anything I didn't catch. In my setup, there is a Raid Controller, and since I don't use Raid, I just disabled it. There is also an unknown device, and it's driving me crazy not knowing what it is. I ran this OS on a previous motherboard and it didn't show up there, so I don't know.

I tried to find a driver for it online by clicking on update driver but nothing came back. Then I made the mistake of uninstalling it, only to have it ask me everytime during bootup that there is new hardware and would I like to try to find the driver for it. So I disabled it. But I'm still wondering what it can be.

I would have attached a screenshot of the properties window for the unknown device but I couldnt get it to upload on here. It does mention something about VIA PCI to ISA Bridge. Hope that helps. But I have no ISA slots!

Also is there any way, through the registry or whatever to just completely get rid of these entries in Device manager? The RAID entry and the unknown device?

I upgraded to Windows 10 a while back. Every time I open the computer I get a pop-up notification telling me the USB device is unrecognized. I have no USB devices in any of my 3 USB ports.
I sent my computer in twice. No help. They just uninstalled everything and reinstalled everything and told me it should be fixed. It is not. I then went about updating every driver in my Device Manager. I uninstalled the Unknown USB Device and then updated
other drivers. Certain drivers (such as PCI Express Root Port #3 - 9C14) when updating would also reinstall the Unknown USB Device, which I would then uninstall and keep working down the list. At the end of updating EVERYTHING I scanned for hardware changes
and "found" the Unknown USB Device. 
From what I can tell, and I know very little about this stuff, my computer can't name one of my USB ports. Since it can't figure out what it's called it can't download the proper driver for it. Since it can't download the proper driver it can't work properly.
The practical result from this is that one of my three USB ports does nothing when I put in any USB item (connect my android phone, thumb drive, presentation clicker, etc).
I've looked on tons of forums. My current thought is that if I can tell my computer what the deice is or download the right driver and tell my computer to use that driver for this device it should solve my issue. But I don't know how to know what the name
of the USB port should be (I imagine it woul... Read more

I have two devices IEEE 1394 and Realtek RTL8139 listed under UNKNOWN in device manager.
I have deleted ALL previous unknowns (about 7) and when I reboot these two are found and drivers are automatically installed but they still end up under UNKNOWN. I tried reinstalling a new driver and it did not because what was installed was determined to be the best.

SO........ Windoz XP sees the devices, installs drivers, but still lists them as unknown and the LAN doesn't work.

I must say that this started after a McAfee update which I uninstalled - but problem still exists.

I've installed a clean Windows 10 x64 on my  HP Envy x360 15-ar052sa and there are two unknown devices in device manager. Perhaps by no coincidence the touch screen is not working. I can see in system infomation (and device manager > unknown device properties > Details > Device instance path) the following codes:ACPI\ELAN0732\3&291F7AFD&0BTH\MS_BTHPAN\7&341F44D5&0&2 <Category name="Problem Devices"><Data><Device><![CDATA[Not Available]]></Device><PNP_Device_ID><![CDATA[BTH\MS_BTHPAN\7&341F44D5&0&2]]></PNP_Device_ID><Error_Code><![CDATA[The drivers for this device are not installed.]]></Error_Code></Data><Data><Device><![CDATA[Not Available]]></Device><PNP_Device_ID><![CDATA[ACPI\ELAN0732\3&291F7AFD&0]]></PNP_Device_ID><Error_Code><![CDATA[The drivers for this device are not installed.]]></Error_Code></Data></Category> Does anyone know which drivers are required? Many thanks

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.

Any help would be appreciated. Also if any additional info is required, let me know and I will post it.

You can go to asus's official website to download drivers, in most cases is a sound card problem.Or you can go to download a "My Drivers", to another similarly configured machine up a backup drive, then copy to your computer up.Good luck.

 So recently I've been receiving driver issues with my PC. I'd be working in FL Studio 12 while in a Skype call with my friends, then all of the sudden the whole entire PC freezes. So, to get a better idea on what's going on I went to the Device Manager, since I figured it might be a driver malfunction. I spot under "Other Devices" some suspicious looking drivers that I do not recognize. I think it might be an ASIO Audio driver that was installed with FL Studio 12, but I am not sure. Here is some more details:  This is details and value of the drivers.--This is general information about the drivers.  In addition, these drivers aren't digitally signed. There's no dates on when it was signed, and the signer is unknown.

I just discovered that in my laptop's Devise Manger, under DVD/CD-ROM drives there are two entries as follows: 1) FvFx CDDVDvx+tech-200 SCSI CdRom Device 2) TSSTcorp DVDWBD TS-LB23A I think TSSTcorp is my dvd drive. What's the FvFx? I wanted to uninstall it but I thought I'd better make sure it's not something important. I googled it and all I could find was tons of websites offering their drivers update service for FvFx CDDCD..... Any help would be appreciated.

A:Unknown dvd drive in Device Manager

To me it appears to be a virtual CDROM drive installed by some game/software you recently or in the distant past installed. Just brood on it.

Without knowing the source - which you only know - the only brute force method of getting rid of it is to try a system restore to an earliest point of time available which may or may not get rid of it. Depends when it - the virtual drive - was created.
