None of the usb ports are not working. In the bios what should be enabled and what should be disabled.

Take a look in BIOS setting if USB ports are disable or issue with Motherboard

as a P/S2 keyboard.plug it in the USB contact in the back.in any USB port.

find out that any other device is working on that USB port? if yes then try with other cd, ask the dealer to provide u other cd. may be any file corrupted on that cd. if any device not working on that port may be the port is defective or may be it is disable from bios setting. go to bios setting while u turn on the pc see the message appears press DEL or press F12 to go to bios seeting. go to bios setting & find USB port is enable or disable. enable it.

Chk whether the USB ports are disabled in the device manager by Right clicking on My Computer and then Manage and then Device Manager
If not disabled in device manager then chk through BIOS. (USB - Enabled or Disabled)
If not disabled then chk for any viruses in ur computer.
Tell me if not solved..

Hi,

It may be disable your USB in BIOS you should check the BIOS & enable USB in BIOS otherwise USB driver not installed on your system if driver issue insert the your Motherboard driver cd install the all driver.
I hope that this has been very helpful for you

Try the mouse in a computer where the USB ports *DO* work.

It is possible that your system does not have the correct "device-drivers" for the USB ports. Thus, those USB ports seem to be "dead".

Turn the computer off.
Connect a PS/2 keyboard and a PS/2 mouse.
Turn the computer on.
Click START
Click Control Panel
Click System
Click Hardware
Click Device Manager
Expand the "USB ports" section of the tree.
Look for "yellow" or "red" marks.
Double-click one of those "problem" devices.
Choose "Reinstall Driver".
If it asks to be able to connect to the Internet, click "yes, this time".
Hopefully, this will install the correct drivers for your USB ports.

1.) Check your CMOS/Bios settings to see if any USB ports are disabled.

2.) If not, check to see that USB ports show in your operating system's device manager or settings. Enable them if they are disabled. Otherwise, you may need to reinstall the drivers that came with your model of notebook computer.

If using Windows XP, for example, go to Control Panel, System, Hardware, Device Manager, Universal Serial Bus Controllers. If the latter is not present and you have USB enabled in CMOS/Bios, you will need to install the drivers. If "Universal Serial Bus Controllers" is present, look within to see if they are all enabled and working properly.
If not, re-install the drivers.

3.) If the above does not work, you may have bad USB ports that will require service by an authorized repair service for your notebook computer.

1. connect U r camera to Back side Mother Board USB Port not for extension or front side port.

2. Check in bios USB controllers are enabled or disabled. if disabled enable it.

3. in windows device manger check for usb controllers
