I hope that "opened" doesn't mean "opened the case and messed around inside". Just "started".
- All USB's on the motherboard? Or are there on the front-side or on a separate PCI-card, also not working?
- What devices did you try? Like printer, mouse, keyboard, USB-stick, internal hard disk. An optical mouse, for example, should light up on the USB-power. Does it? If you've got a USB-printer connected and try to print to it, what exactly happens (what error message?)
The worst-case scenario, probably, is buying and installing PCI USB-card.
when i opened my pc yesterday, none of my usb worked.
they are not detecting any devices.
i am using windows xp
i have 5 usb port
my device manager is showing usb controller and usbs are enabled
please tell me what to do????????
