I have Windows XP SP2 on an Intel motherboard with a P4 processor. All of its USB ports are malfunctioning. When I connect a speaker, mouse or anything through those USB ports, they are working fine. But as soon as I connect a USB drive (pen drive), it detects it for around half a minute.
As I try to copy something to it or to use it any other way, it shows:
The device is not available
I connected an external PCI USB card, but that card is also facing the same problem. The system is not infected.
What can be the causes of this problem and what are the remedies?
EDIT: booted with Ubuntu live CD. problem still persists.
