Imaging Devices Listed As Unknown In Device Manager?
May 13, 2005
All of a sudden, the imaging devices attached to a computer with Windows XP Pro SP2 are showing up under the Unknown category in the Device Manager. The
devices are listed correctly by their names under Unknown, but the software won't communicate with them.Windows can see the devices, but it does not know what type of devices they are. It is only the imaging devices. One is a Canon 4200F Canoscan scanner, the other is a Sony Camcorder, and the third is a hardware capture device (Pinnacle Moviebox). The Canon scanner is a USB 2.0 device, while the other two are attached through firewire ports.

I had some trouble last night and today with getting rid of a virus. Now that it is gone, I am having sound problems (maybe related, maybe not). This morning, when I opened iTunes I got a message that there was no audio device detected. After trying several things, I rebooted. Magically, I could play music again. However, a short while later, I again got an error message telling me that there is no audio device found, even though it shows up in Device Manager as working properly. The problem goes away for a short time after I reboot, but returns. It is Realtek AC 97. Why won't my computer keep recognizing it? (It tried going to Realtek's site to download an update. It has updates for Windows 98, 95, etc., but not for XP. Or at least I couldn't find it.)

My primary hard drive crashed and my back up that holds all my pictures, mp3's and other important items is still ok. I reinstalled windows fine on a new hard drive with no problem. My back up hard drive is not showing in my explorer list though. Does anybody know how I may access it? I've installed all motherboard software and it still is not there. I don't wanna reformat that drive unless its the only thing i can do.

I have XP and when I open my device manager, no devices are shown at all. This is not corrected by the usual microsoft help (i.e set services plug/play to automatic).

I changed the system boot in "MsConfig" and now my sound, scanner and my printer don't work. I looked at the device manager to see if there was an error with the soundcard or something, but all devices have vanished from the device manager. I just tried to connect my ipod to the computer, and it said the software can't communicate with the ipod.

I had to reinstall windows XP because my OS would not load and I got all the drivers reinstalled, diagnostic ran smooth and everything came up working ok etc but my device manager won't recognize anything! The compy says my audio mixers are not there, my USB devices are not working, hardware wizard is not responding, microsoft updates are not working, Dell's driver downloads are calling out for something that isn't there and I really need this fixed ASAP so I can get to my external HD.

Last night I installed ATiTool 0.24 over my 0.25 version (stupidly). I also did a BIOS update and installed Cat6.3 and then AVIVO converter. When I rebooted, I had this new PCI device requiring a driver,but it's an unknown device and doing an auto update helped me.I can't get rid of this pesky PCI device (tried uninstalling but Windows detects it again after restart/boot-up). All my stuff is working, so I don't know where this critter came from?

I have deleted an sound object that allows it in device manager and allowed XP to load wht it will. I still have no sound. I checked for sound services in services and they are started as well.If I load Knoppix and test, my sounds work so I am assumming it is not a hardware problem.

I found something in my Add/Remove Programs called "My Way Search Assistant", which I removed - evidently successfully,as there is no trace of it in registry or programs. My problem is, however, the entry in Add/Remove remains but only with the name "My Way Search Assistant" and when I click on it all that shows is "Used Rarely"It has no size and no longer has any option to change or remove.I have looked for registry entries there are none is there a program listed.

Running Windows XP on Emachines ET1161-07. Installed all drivers that I could find, since EMachines does not represent XP. Tried Realtek audio and HD audio, tried Intel, didn't work. Tried NVidia, as it has an NVidia motherboard. Spent too much time on this computer. Can anyone lend a hand? I know it's got something to do with Audio, as there's no audio device detected in Sounds, under Control Panel.Customer has to have computer today.

I had this problem last time when I fresh installed Windows XP Pro on my computer. I don't know the time, but it happens at least 30 days after I reinstall the OS and software. Today, my computer prompted me to install drivers for a PCI Input Device, but I haven't installed any new hardware for months. Basically, I haven't touched the inside of my computer for that long. So why is Device Manager prompting me to install this mystery device? Hardware ID shows that it is from vendor 1102, which is Creative, and I have an Audigy 1. Also, my FireWire port is Code 10, the device cannot start. So I'm thinking the mystery device is the same firewire port. But why show up as a separate device? I tried removing the devices and restarting the computer, but they return to haunt me again. The device properties for the PCI Input Device says PCI SLOT 7, AND I DONT HAVE A 7th slot! Can someone help me, please? Device manager shows my 1394 Net Adapter with a yellow exclamation, and it has code 10, device cannot start. There is an unknown device, the PCI Input Device, which doesn't allow me to install any drivers for it, yet it has the creative Vendor ID 1102. It shows itself as being PCI Slot 7.

I have a feeling that this is simply a case of some registry settings which need adding/modifying/deleting but exactly which ones and what values I do not know. No, I haven't tried re-installing XP.

A friend of mine has a 4 yr. old PC running XP Home with 128Mb of memory. He's had problems with programs aborting recently. I tried to run Device Manager to make sure there were no issues there. It briefly brought the screen up, then it went away. The same thing happened to Task Manager when I tried to see what was running and how much memory was being used. Anybody ever see this behavior before? I might try installing a memory cleaner pgm (ie. Memturbo), but I'm not sure I would even be able to get it to run. The hard drive amd memory seem to have no errors.

My computer cannot detect any cd's in my DVD or CD drive. When I open Device Manager the CD/DVD devices have an error. This error: Windows successfully loaded the device driver for this hardware but cannot find the hardware device. (Code 41) Click Troubleshoot to start the troubleshooter for this device.When I run the DriverScan it simply doesn't even have an entry for the drives, probably since it thinks it doesn't even exist at the moment.

Anyone know how I can rename a device in device manager, (or the registry), so it doesn't show #2 after the device.I used the leadtek driver uninstall tool last night. And it removed the drivers I had for this Leadtek Deluxe tuner alright.BUT it also renamed my onboard Gigabit LAN (onboard) to #2 my scanner to #2,
and removed my Nvidia drivers for the video card.And reverted the videocard drivers to MS Nvidia drivers.I managed to fix the scanner entry by uninstalling the drivers, then rebooting and reinstalling the drivers.And I managed to fix the videocard drivers, by reinstalling the Nvidia drivers.So, yup, anyone have any idea how I can change the board LAN, so it doesnt have #2 after it? sing XP Pro SP2

I'm using Win XP SP2 . I installed a second CD rom drive which was obviously no good because it caused the other one which is perfectly ok to show up in the bios as an unknown device. Both showed up in the bios as unknown device but the the first still showed up in system hardware the second one didn't.I removed the second one from the computer and the first one then showed up accordingly in the bios as the proper device but the bios is still saying the second one is an unknown device. Every time I start my computer I get the message secondary device missing press the F1 key to continue.

Just put together my new system and all is working well, but I am left with this unknown exclamation in the "device manager". I can't figure out what it is.
The only thing device manager says is,Location: on PCI standard ISA bridge The drivers for this device are not installed. (Code 28) and in the conflicting device list it says Memory Range FED00000 - FED00FFF not available.

i installed an usb device,and all the drivers for it,it worked for two days, it was recognized.Now it will not recognize the device.I have tried uninstalling and reinstalling the device drivers, all the software that used the device. and even tried to install the driver by locating with 'have disk' browse. i have tried all the directories that the drivers were installed to, and then some. and also the install disk. Device manager says that its an unknown device, and theres no problem with it. but will not update to the proper drivers. How can i alleviate this problem short of reformatting my computer.
