USB ports not recognized

Dell Vostro 1500 notebook
August 2, 2009 at 14:31:32
Specs: Windows XP
My hard drive crashed so I installed a new one--320GB and everything appeared to be working, but when I tried to plug something in to one of the USB ports, nothing happened. It appears that nothing is being recognized on the USB port. Any suggestions?

Go into your bios Setup and make sure the USB controller(s) is(are) enabled.

What are you trying to get to work that's plugged into (a) USB port(s)?

A USB device may not work or not work properly unless it is plugged directly into a port built into the laptop.

An external hard drive may need to be plugged into TWO USB ports.

Is the 320gb hard drive internal or in an external enclosure?
If it's internal have you installed Windows on it yet? Some USB devices will not be detected until after you have installed Windows, and possibly will also need drivers to be installed for them.
If you were using a PS/2 mouse during Setup, or the touchpad during Setup, a USB mouse, the first time you connect it, will not work until the desktop has fully loaded and the USB mouse has been detected. If you need to logon and/ or enter a password while booting, use the touchpad, or use the Tab key to toggle which selection is selected, the Enter key to select it.

If you're trying to get into the bios with a USB connected keyboard, Legacy USB, or USB keyboard, or similar must already be enabled in the bios Setup. On more recent systems that's usually enabled by default - on older systems it may not be, and you have to use a PS/2 keyboard in order to change the setting.

A USB mouse, or any mouse, usually does not work in the bios Setup.

If you are trying to adapt a keyboard or mouse for use in another type of port from the one on the end of it's cord, the simple adapter (e.g. PS/2 to USB) won't work unless the keyboard or mouse is a "combo" one that is designed to be used with, and has the circuits wired up for, both types of ports. A simple adapter for a keyboard - often purple - may not work with a mouse, and a simple adapter for a mouse - often green - may not work with a keyboard, because it doesn't have the proper connections for the other use wired up.
