I recently purchased a Logitech USB headset, and it worked fine for the first few days I had it. I noticed, however, about two days after the purchase that it failed to work. My USB mouse worked fine, however, so I figured it was the headset. I discarded the headset and continued using the built-in microphone. Later, however, when I had to restart my system in order to install an update, my mouse stopped working as well (they work fine on other computers). I looked to see what the problem was in the Device Manager, and my Universal Serial Bus driver was apparently damaged.
As well as my Standard Enhanced PCI to USB Host Controller and my Standard OpenHCD USB Host Controller. I attempted to uninstall, reboot my system, and then let Windows automatically reinstall the drivers, but they always fail to do so in the middle of the installation process. I then attempted to do a system restore the day before both the Windows update and then before the problems with the USB headset, but the problem persisted. If all else fails, I might have to reformat, but I do not want to have to result to that extreme since I cannot salvage anything of value onto an external hard drive.
The PCI to USB Controller has the error: Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)
The OpenHCD USB controller has the error: Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)
The Universal Serial Bus USB Controller has the error: The Drivers for this device are not installed (Code 28). The system cannot find the file specified. To find a driver for this device, click Update Driver.
I currently run on an HP Pavilion dv7 Notebook PC and run Windows 7 Home Premium Service Pack 1 (64-bit)...

I am using an Asus P6T Deluxe V2 motherboard and Windows 7 Professional. I am having a problem with my external (esata) disk drive being recognized by the OS. It used to work and now it don't?? During boot up I see the drive in the bios messages on my screen. Also when I look in device manager it shows the drive and says this device is working properly. However, when I click on "computer" its not there and no software program such as backup finds the drive either. I have tried uninstalling the drive in device manager and then rebooting. No luck? I am not sure when it quit working or why. Its not the drive as I have tried more than one and they are recognized when used in the USB port. I have uninstalled the Marvell 61xx RAID controller in the device manager also but no change?

I noticed that I don't have any Internet connection (red x) but my laptop seems to have Internet connection. I checked my Device Manager and it seems that Network Adapter is missing instead there is 'Other Device' and below it was a 'Unknown Device' (with a yellow exclamation mark). I tried to install the driver but no luck via USB. I also did a system restore point but still no luck. I also tried to 'Scan for hardware changes' and still again, no luck... It's still unknown device.
I searched the Internet and they said the resetting the CMOS will solve this problem, is this true?
My specs:
Processor: AMD Athlon II x2 250 3.00GHz
Motherboard: EMX-AMD880HD3-PRO (Emaxx Technology)
RAM: 4.00GB
GPU: Sapphire Radeon HD 6670 1GB GDDR5 (OCed - is this safe?)
PSU: 600w
Operating System: Windows 7 Ultimate SP1 64-bit

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 treeThe hardware in question is an onboard LAN card on a ASUS Sabertooth X58 motherboard, the lan card is listed in the bios as a RTL8110SCLANI 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 ha

I just installed Windows 7 on an Acer Aspire 7551. The internal wireless network adapter does not appear in the device manager. So I am using an external USB wireless adapter until I get the internal one to work. I tried to contact Acer but if the system is out of warranty, you can drop dead for all they care. I went to their support website and downloaded a driver for 'Wireless LAN Driver'. They have two different vendors. I chose Broadcom. It downloaded a zip file and I don't know how to install it.

It was working fine, I didn't install or change nothing (mostly is used as MediaCenter). It was working perfectly without any change for months. Then I shutdown one day as always, and when I reboot the next day no network is present.The PC is an Acer Aspire X3900 desktop with an integrated intel NIC. This is what I have seen: In the Windows 7 network configuration panel there isn't any NIC present. IPCONFIG shows nothing, no adapter is listed (is not like when you unplug the network cable and the adapter is listed buy without the IPs; now the command shows nothing at all). But, and that is the weird thing, in device manager all seems fine. The Intel NIC is listed without any warning mark. Looking the properties, all looks ok. This is what I had already try: I reinstalled the NIC drivers. No changes. Reinstalled the chipset drivers. No changes. Uninstalled NIC drivers with an Intel utility. Then I rebooted and reinstalled the drivers when windows detected the new hw. No changes. Disabled the NIC adapter in device manager, reboot and re-enable. No changes. Uninstalled the NIC adapter in device manager. Reboot and re-install the drivers when windows detect the new hw.No changes. Disabled the NIC adapter in BIOS. Boot windows, shutdown, re-enable the adapter in BIOS, and reboot. einstall the drivers. No change. Recover the system from an old recover point, but no change.

Yesterday I got my friend to download windows 7 on my mac via bootcamp. I got it back today and I tried my wireless at home but didn't work. So I tried LAN line as well, which didn't work either. I went through few sites, they all told me to go on device manager and update my drives. The problem is that i can't find either modem or network adapter on my device manager.

Just reformatted my alienware laptop because I haven't used it in months. Now I don't even see "Network Adapter" listed under device manager so when trying to install the driver i don't think it had any effect. Running m15x windows 7 home premium 64 bit.

I have an emachines em350, I installed Windows 7 as a clean install onto a new hard drive.
It's al sweet except the sound and network adapters have not installed. In fact it seems that Windows 7 is declaring they never existed in the first place.
I have retrieved the latest drivers, Windows 7 spits them out stating that the devices are not present. I have tried the older versions using compatibility mode. I have tried install legacy hardware. I have tried to flush them out through command prompt. Nothing.
The sound 'card' (which I believe to be onboard) is seen by device manager, but refuses to have anything*to do with drivers.
The LAN I also believe is part of the motherboard, but it just won't show at all.

In Windows Home Premium 64bit we encounter this problem on a machine after trying to uninstall a norton product manually.The norton software led to serious problems of randomly emerging BSODs.As system uninstall did not work we researched a tutorial on how to manually uninstall the soft.t can be found here Enterprise Support - Symantec Corp. - How to manually uninstall the Symantec Endpoint Protection client from Windows Vista, Windows 7, and Windows 2008 R2 64-bitEverything worked smoothly until the last three steps of the routine failed (12.-14We can not uninstall/delete the wireless network adapters as described. After clicking "uninstall" there is the window that asks for confirmation (to uninstall) but after clicking "yes" the device manager window simply refreshes - and the device remains unchanged.

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.

Have recently purchased a small usb inspection snake camera with led light and when testing it plugged it into two desktops computers (one xp pro not sure of the other as it was a network work computer) It automatically loaded the drivers and brought up a screen automatically with the realtime image.(no driver disc came with it). However plugging into my windows 7 64bit sony laptop it signals a connection beep, loaded drivers automatically but wouldn't open or show up on my computer disc manager as an external usb source to click on. It does however show up on device manager as a usb camera and when I unplug and replug in it disappears and reappears so I know I have the right camera (not the lap top webcam inbuilt one that shows USB 2 Camera). Have tried updating drivers automatically and uninstalling it etc. Need it to work on the lap top so it can act as the movable screen for it?
