USB ports wont work

Try a different USB device on each of the USB ports on your computer.
Hopefully, all your USB ports are working correctly.

Try a different USB port on your computer.
Hopefully, the SanDisk will be detected on one of the ports.

Try a USB port on a different computer.
If the SanDisk still is not detected, then spend $10 to buy a new 4GB flash-drive.

1) Power down or reboot your system.
2) As the pc is restarting, press the F2 button to pull up the "Setup" screen.
3) Right Arrow to the "Advance" tab
4) Make sure that all devices are enabled
5) Arrow down to "Miscellaneous Devices"
6) Make sure "External USB Ports" is also enabled

replace or usb cable...f not chek usb port of ur unit

In order for the two USB ports on the monitor to work, the monitor itself has to be connected to your computer via another USB cable with connectors that look like this:

The flat connector goes into an available USB port on your computer, the square one plugs into your monitor. Check if your cable is connected properly or exchange it with another one.
To eliminate that there is something wrong with your "not recognized device", plug this device into another USB port of your computer. The reason to preferably remove the device safely in Windows is that you can loose data if you just unplug it. If it is an external harddrive, it can get damaged, because you interrupt the power and the read/write head can get "stuck". So check this device on another computer or USB port.

If you have any other questions or something is not clear to you, just come back here and leave a comment and I'm happy to help.

try to change a new USB cord, and if it does not work the problem is a device then

You'll want to verify your computer recognizes your usb ports.
In device manager, look to see that you don't have anything with an exclamation mark, question mark, or red X on it. Make sure you have the usb ports listed under Universal Serial Bus controllers. If nothing shows, your usb ports may be dead. Depends on the age of your computer and what might have happened to them.

Device manager- right-click My Computer and go to properties, then select the hardware tab.

Was referring to the configuration. P3, P4, etc. Older boards that have a USB 1.1 port sometimes have compatibility issues with some USB 2.0 devices.

I recommend trying it on other XP-based computers. If it still doesn't work then the device has a problem. If it works then it could be a compatibility issue with your PC.

Hope this helps.

You should try a regular ps/2 mouse and keyboard.  You probably don't have the USB drivers installed for the new board.  After you get booted into windows you'll be able to install those.
