USB devices disconnect automatically

Specs: Windows XP SP3, Intel Core Duo E7400 @280GHz/ RAM 2.99 GB
Hello people! I've got a problem with my USB devices (both front and back): whenever I try plugging a device Windows recognises it, but it soon disconnects by itself. It's really annoying and already ruined several files that were being copied.

It has happened with iPod's, regular mp3 players, pendrives, cameras and whatever other device I try to connect.

I reinstalled the USB ports but the problem persists, and in the Device Mangager there seems to be no problem under the USB ports.

There are no virus in the system: scanned with Avast!, Nod32 and SUPERAntiSpyware.

I already took it to customer support and they told me it was no hardware problem (motherboard is OK, etc.) it was a software issue so they couldn't help me.

I'm running Windows XP SP3. Any help would be really, really appreciated.

check your BIOS settings and try changing your settings. (support Legacy)
Also check your power setting and see if windows is allowed to turn off USB to save power.
Is this happening on all devices or only one?

Thank you for your help!

It is hapening to all devices. I already checked and the save power setting on al USB ports is set not allowed.

On the other hand, how can I check my BIOS settings?

I also keep having this annoying message every once in a while:

"Windows: no disk. Exception processing message c0000013" and some parameters. Whatever I click it keeps popping up again.

I checked the device manager in My PC and all devices have been disconnected fine and it shows no errors. What could this be?

Thanks again!

Thanks a lot, but could you please describe me how to get there? I don't know how to do that or what it is about.

And once I reach legacy support, what should I do?

Thank you again!

each brand has a different way of accessing the bios. You can search google with your model number and check how to access the bios. Then look through your onboard settings for USB.

Hey! I accesed the BIOS. All USB settings were listed as Enabled and "Legacy USB storage detect" was also Enabled, so I didn't change a thing.

Nonetheles, I did this: "go to safe mode by tapping the F8 key while booting, choose safe mode, enter with the admin account. once there right click my computer,,properties,,advanced..hardware,,device manager,,click the plus sign at usb and remove the entries, reboot and let windows reinstall them. UNplug all your usb devices before doing this then replug after it is done reinstalling the ports."

And now things stopped disconnecting (or so it seems). However, that annoying error message keeps popping up. Any ideas?

check in device manager/usb devices that each one under the power management tab is NOT checked for power management.

Windows sometimes thinks the devices aren't being used and shuts the power to it due to this setting.
