How I Fixed: USB Ports Don’t Work After New OS Installation

driver installation order

Hello everyone,

Note: In this previous post I wrote about proper driver sequence in a Dell machine.

I got a home made computer from a client and the USB ports were not working. The operating system (Windows XP) had just been freshly installed as well as all Windows updates. Everything was working great except for the USB ports.

The motherboard  manufacturer was BIOSTAR, so I went to the BIOSTAR site and looked up the exact motherboard model (P4M800 Pro-M7). I downloaded the appropriate drivers and installed them.

Still no working USB ports!! What is going on here?

Well, don’t ever underestimate the importance of proper driver installation sequence. This is what I had to do:

1) Reinstall Windows XP

2) Go to the BIOSTAR site and install the drivers in this order:

A) Chipset (crucial that you install this driver first)

B) On-Board VGA

C) On-Board LAN

D) On-Board Audio

E) USB 2.0 Controller (this was the driver that was needed to make the USB ports function)

3) Go to Windows Update and download/install all updates from Microsoft

The result? All USB ports worked as they should and the computer worked flawlessly!

Professor Randy says: Install all motherboard drivers in proper sequence before installing any updates from Microsoft. Your computer will function at an optimum level and you will avoid many future glitches.
