I have a T42P laptop with windows xp pro 2002 with service pack 2. When I put in a USB device it does not recognize it. In Device Manager, it says all the USB controllers are working properly, and that the USB Root HUB are all ok. I am so frustrated. HELP

Laptop not recognizing device when plugged into laptop how to fix

The computer is not recognizing the device because the appropriate software or driver is not installed on the device.

Most of the time when you connect a smartphone into a compatible laptop the device drivers or software automatically install, so the laptop may recognize the smartphone.

Here are some possibilities as to why the device is not recognized.

1) The USB port is bad.
2) The USB port is not activated
3) One of the devices does not support the other

Here are a few possible troubleshooting solutions:

1) Go to the smartphone manufactures website and download and install the updated device driver and software then plug in the device to see if it is recognized.
2) (if Windows OS) Go to the Device Manager to see if the device is showing up when it's plugged in. If you see the device in device manager right click the device and choose to update the driver.
3) (if Windows OS) Additionally, in device manager you can check your device's USB ports to see if there is an issue with the ports that may be resulting in the smartphone not being recognized. You can choose to re-enable the USB ports or update the software for the USB ports.

Hopes that helps resolve your issues.

If the laptop was "designed for Vista" or "designed for Windows 7", then it's quite likely that the manufacturer did *NOT* create any device-drivers for Windows XP. Thus, you'll be missing support for your LCD screen, your wired/wireless network adapters, your USB-ports, and so on.

Note that Microsoft will stop supporting Windows XP Service Pack 2 as of July 15 this year (2010). So, trying to install an "unsupported" operating-system is *NOT* a good idea.

Stick with the operating system that was shipped with the computer.

I have an Asus eeePC 701 which came with Linux but I replaced that with a madified Win XP Pro. Now the USB ports seem only to be 1.1. I want to download a 2.0 enhanced controller to see if the ports can be...

Check if your XP installer has service pack 2. If not download and install service pack 2 on Service pack 2 automatically comes with USB 2.0.

Hope this helps.

I have a Dell Inspiron 9200 running Windows XP pro. The other day I was running an external hard drive through a USB port...and since then...all my USB ports will not recognize ANY device. They run power...

A remedy would be buying a card that goes into a slot on this pc that has usb ports- giving that a shot will help you other then that the motherboard would need to be replaced at this point the cheap way out would be to just by a card- Thanks

USB plug in recognition


To be honest, I am not sure if your post/query was intended for me. However, it shows up in my queue so i couldn't escape it. I will take a shot at the last part.

Sony DSC-W130 has 15MB Integrated Memory and support for Memory Stick Duo, Memory Stick PRO Duo cards. Generally unless you install the software for the Cybershot DSC-W130, Windows XP/Vista will pick it up as a Mass Storage Device.

The Mass Storage Device emulation allows you access to pictures/video taken; copy, move, delete etc. If you can do these, then the DSC-W130 is working as designed.

However, if there pictures on the DSC-W130 but you are unable to access it, then that is a worry and a poblem. Note if you have a memory stick installed. The internal memory will be inaccessible. You will have to remove the memory stick before the internal memory initialises and is accessible

I am afraid I am not an expert on Sony DSC-W130. My response is best effort

"USB Device Not Recognized" - any usb device

1-Make sure you are using XP SP2. You probably are but just in case....

2-Unplug all USB devices

3-Uninstall any software for the devices you just unplugged

4-Reboot into safe mode and open the device manager. Make sure to choose the show hidden devices option

Note: Follow the order of removal exactly and this MUST be done in safe mode only!

5-Remove any entries for USB peripherals like scanners and printers

6-Remove any entries for HID devices or Combp USB devices

7-Remove all USB root hub entries

8-Remove all USB host controller entries

9-Reboot to normal mode, let Windows reset the USB stack and try your thumb drive.

If this didn't work then repeat steps 1-8.
Staying in safe mode, right click in the device manager and scan for hardware changes. Let Windows reset the USB stack and try your thumb drive again.

Also when doing any of this try and get a hold of another thumb drive and try it instead of yours. Your thumb drive could be the source of the trouble. We had similar issues we tracked down to a bad batch of Memorex thumb drives.

USB ports don't recognize plug-ins

Latest BIOS and Chipset update would be very helpful to resolve the issue. Especially BIOS update contains very important fixes and enhanced functions. Latest release is 4/2/2007 dated. If yours older than this you can update. After BIOS update you can also update the chipset if issue persists. Here is the link for all drivers you need.

Good Luck
