Hi there,

The usb drivers are part of your chipset drivers, so lets try and get this sorted. The reason that they work in Vista, is probably because Vista has added support for your chipset and XP SP2 doesn't.

Try installing XP from scratch. First you need to completely wipe your hard drive. Use the XP boot disc, you need to delete the hard drive partition as well. This way, you will start with a RAW drive.

Set up a new partition, and let the XP disc format the drive with NTFS. Do NOT use quick format. Then let XP copy the files and install.

When XP has installed, get your internet set up, and download XP Service Pack 3 from Microsoft:

You will notice that Microsoft have written not to use if updating just one machine. Ignore this. The reason is because this is the FULL Service Pack, hence it being over 300MB.

Once you have SP3 installed, your system will restart. Open Windows Update, make sure you have this set to update all Microsoft products, then download all updates. Restart your system and check if your usb's are working.

If they are still not working, go to the laptop website and download the chipset drivers from there, but make sure you are downloading the drivers for XP. If not, then go to the Chipset manufacturer's website and download from there.

Let me know how you get on

    No problem, see what happens after you've tried a fresh install.

    Don't forget to let me know how you get on


  • Timothy Farley Dec 19, 2008

    Also, wasn't sure where you were getting your driver from, but I have taken a look, and just in case, the LG ED510 drivers can be found here:

    The Chipset drivers are on Page 4.

    Ok, I'm with you on this one, willing to give anything a shot. Hope it works

Hay! my laptop is toshiba satellite A135 s4527 home vista. but i run my laptop with oprating system windows XP2. how it possible. please help me

Hello and welcome to fixya.

In your case, im assuming you refer to the "Vista sticker" that is on the laptop. If a computer is vista-compatible this doesn't mean that it is not able to run older Operating Systems (such as Windows XP SP2) as well.

The sticker on the laptop just referes to the type of Operating System that came pre-installed with it. Now if you bought the laptop and asked your salesman for a DOWNGRADE TO XP Operating System or if this is what he understood then it will probably come with Windows XP instead of Vista Home.

This also applies if you are working for a company in which case the company's IT Department will decide what type of Operating System is to be installed on this computer.

Overall: Newer computers/laptop models that support Windows Vista can also run Windows XP

ALSO: Check for the OEM sticker in the back of the laptop or bottom (it looks like THIS for XP or THIS for windows vista Home Premium). This determines whether you can use a vista DVD to upgrade your computer later from XP to Vista.

If you have any more questions just let me know.

Windows is showing a remove hardware icon. when I click on it, it wants to remove the cd/ is hl-dt-st rw/dvd gcc t10n. I've tried disabling the driver and restoring it, disabling device and...

Operating System Windows Vista™ Ultimate, Windows Vista™ Business,
Windows Vista™ Home Basic,

Try formatting your windows into windows vista or windows 7. It might solve you problem.

Windows os

Its true. the Bios or HDD driver wont allow you to install Win XP on it.. This BIOS is compatible with only Win Vista. The only easy way to do it is by creating 2 partitions while installing vista. once vista is installed- install XP with Dual boot and than format the vista partition.

I want to install win Xp Sp 2 but i can't do it

you need to have internet connection first then go to the website and you need to update the operating system from that site. in the process of updating it there will be an option there to update it to service pack 2 already.. sometimes you need to update other things first in the same website before that option comes up.

"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.
