The manufacter website almost always has the proper drivers. if they do not contact the 800 number on the website and they should provide you with the url for the driver or at least a way to get the driver.

OnBoard USB Ports Not Working and No PS/2 Ports!


When you boot the machine does it tell you what key to hit to get into the BIOS or System Setup? If so, press it. Maybe you need to try another keyboard if it won't allow you to press a key to get into the Bios or System Setup.

My usb ports are not recognizing any devices such as my iphone, ipod, etc. I have a dell dimension 4700 runnning win xp sp3


It seems that many people are still getting the 'USB Device not Recognized' problem from time to time. Unfortunately there is no easy fix.

Firstly, it's recommended that you make sure every one of your motherboard drivers are completely up-to-date, but you probably already knew that.

In XP, after a USB port isn't used for a long while the USB driver built into the OS sets the OHCI controller to suspend. When you plug a device back in, it can sometimes fail to 'wake up' properly. This problem was supposedly fixed in SP1 but there is a related registry hack that may still be able to help.

Run regedt32.exe and navigate to;

HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Services\Usb

Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. Then restart the PC.

A long shot perhaps, but I recall having similar problems with a USB hub built into my Microsoft keyboard and adding this key seemed to solve it. It wouldn't hurt in trying icon_smile.png.

Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force XP into refreshing the USB driver stack.

Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software. Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;

1. USB peripheral devices (printers etc.)

2. HID and/or Composite USB (Human Interface Devices) You're using PS/2 input devices so you may not have this entry.

3. USB Root Hub(s)

4. USB Host Controller(s) (Universal or Enhanced Host Controllers)

Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.

I have a Dell 530 S Dell Inspiron. Its Webcam has stopped working. Any solutions


The very first step is of course to check your web cam connection. Most web cams use the USB port to connect to the PC, so check if your USB cable is properly plugged. For build-in web cams this steps does of course not apply. Many new laptops have a build-in web cam. Also try connecting your web cam directly to your PC instead of through a USB hub (if you are using one).

The next thing is to do is to check your Windows Device Manager and see if the hardware is recognized and installed properly.

It might be that the hardware is recognized as a camera, but the right drivers are not installed. The yellow explanation mark will indicate a problem.
Other devices in Windows XP device manager

If the device is not recognized in Windows XP, Right-click the device, and in the pop up menu select Update Driver Software. Then follow the instructions on screen, but make sure you allow Windows to search the web for updated drivers.

In case no driver for the web cam can be found, you can try a third party driver finding program that scans your PC for installed hardware and allows you to install missing drivers.

If this fails, the next step would be to un install the software that came with your web cam. Use the Add or Remove Programs feature in the Control Panel. If that does not work you can use a third party un installer.

After un installing the software, restart your PC and then reinstall the web cam software. In most cases this will solve the problems. Depending on the software, you might need to unplug your web cam during the software installation.If your problem is not fixed then you have to buy a new one.

Hope the above information will be helpful to you.
Thanks.

New Dell desktop can't recognize external hard drive


I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especialy true if you move a HUB to another port

If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further

My Dell Dimension 2400 does not recognize plug & play for my HP OfficeJet Pro L7650 all-in-one. If I add the all-in-one manually, the computer says it's offline. I've uninstalled & reinstalled the...


My solution was very simple...I just threw my computer out the window! Seriously, the problem has not been resolved...it seems that several types of Dell computers (in my case, the Dimension) have a problem with HP all-in-ones with regard to the USB 2.0 having enough power to recognize the plug and play option when installing the HP product. Dell's only solution (that I could find) is to operate the HP product thru a USB hub...so I guess I'll try that first and, if it still doesn't work, I'll probably just upgrade to a newer non-Dell Dimension computer.

I plugged my Memorex TravelDrive into my computer. It has always worked perfectly. This time I got the message that the USB device was not recognized and I can't get into my files.


THE FOLLOWING IS COURTESY OF MICROSOFT Help and Support

When you plug a USB device into a Windows XP-based computer immediately after the computer comes out of standby (S3) or hibernate (S4), the computer may not recognize the USB device. When this issue occurs, the USB device may be listed in Device Manager as an unknown device, and you may receive the following warning message:
Unrecognized device has been found.

This issue occurs because, when the computer comes out of S3 or S4, there is a five- to ten-second period when the selective suspend feature of the USB driver will interfere with detection of a new USB device connection. The time period depends on several factors. This includes the following factors:• Host controller hardware
• Attached hubs
• Attached devices
• USB driver versions
• Support for USB 2.0
• Additional system hardware or configurations that may change the timing
There may be other reasons that a USB device is not detected

Method 1
loadTOCNode(2, 'workaround'); After the computer comes out of S3 or S4, wait five to ten seconds before you plug the USB device into the computer or hub.

Method 2
After the computer comes out of S3 or S4, unplug the USB device, and then plug the device back into the computer or hub.

Method 3
Use the Device Manager to scan for new hardware. Follow these steps: 1. Click Start, click Run, type Devmgmt.msc, and then click OK..
2. On the Action menu, click Scan for hardware changes. This causes Windows to recognize new devices.
3. Close Device Manager and Control Panel.

Method 4
Disable power management of the USB hub.
Note If you perform the following procedure, you may also reduce the battery life on a portable computer.
To disable power management on the USB hub, follow these steps: 1. Click Start, click Run, type devmgmt.msc, and then click OK.
2. Expand the Universal Serial Bus controllers node, and then follow these steps for each USB Root Hub that is listed: a. Right-click the USB Root Hub, and then click Properties.
b. Click the Power Management tab.
c. Click to clear the Allow the computer to turn off this device to save power check box, and then click OK.
