Guest sjmarks Posted July 14, 2007 Posted July 14, 2007 There are 4 USB ports on my computer. Often, one or more fails to work and the device that is plugged into it is not recognized. One reboot usually corrects the problem but not always. Does anyone have any idea of what might be the problem? I don't recall having this problem before I did a clean reinstall of Windows XP.

After you did the clean install, did you remember to install the drivers for all your hardware? If not, you need to do this. General driver information: Never get drivers from Windows Update. Get them from: 1. The device mftr.'s website; OR 2. The motherboard mftr.'s website if hardware is onboard; OR 3. The OEM's website for your specific machine if you have an OEM computer (HP, Dell, Sony, etc.). Read the installation instructions on the website where you get the drivers. To find out what hardware is in your computer: 1. Read any documentation you got when you bought the computer. 2. If the computer is OEM, go to the OEM's website for your specific model machine and look at the specs (you'll be there to get the drivers anyway) 3. Download, install and run a free system inventory program like Belarc Advisor. The older Aida32 is good for this, too although it might not work on Vista. http://www.belarc.com/free_download.html - Belarc Advisor http://www.aumha.org/free.htm - Aida32 (hosted on Jim Eshelman's site) B. Since you didn't mention what USB devices you are connecting, there is always the possibility that you are attaching too many power-hungry devices for what your computer can handle. If this is the case, then get a powered USB hub. Malke -- Elephant Boy Computers http://www.elephantboycomputers.com "Don't Panic!" MS-MVP Windows - Shell/User
Guest sjmarks Posted July 14, 2007 Posted July 14, 2007 Re: Intermittent USB problem I am using a powered hub but that is connected to one of the 4 USB ports on my computer. My computer manufacturer refers me to Windows Update to obtain the USB drivers. Microsoft "support" tells me "the windows xp service pack 1 installer is designed to update all drivers and all files that are included with windows xp. Because USB 2.0 drivers are not included with windows xp, you must follow the steps in this article to obtain the latest drivers after you install service pack 1." After the reinstall of Windows XP, I went to Microsoft Windows update page and downloaded everything recommended. I don't specifically remember installing Service Pack 1. Would there be any problem installing Service Pack 1 now?

If you have not yet installed SP2, now is a good a time as any to start. You start by first insuring that your computer is free of malware and has BIOS upgrade if needed. Then, you obtain the SP2 CD and follow the instructions. I spent about 2 hours installing SP2 and the subsequent patches. SP2 includes all of SP1 plus quite a bit more. Jim

What about the drivers? Did you install the drivers for your motherboard after your clean install? I didn't see the answer to that question but I may have missed it. If you already have SP2, you still need the drivers per my previous post. Of course, it is always possible that this is a hardware problem and the USB ports on your motherboard are going. If you have a Desktop computer, you can get around that by putting in a PCI USB adapter card. They are very inexpensive.

Guest sjmarks Posted July 15, 2007 Posted July 15, 2007 Re: Intermittent USB problem I installed audio and video drivers after the reinstall. I can't remember any others. I know that I did not install any USB controllers. I don't think that the problem is with individual USB ports because they all work except when they don't. SP1a has the USB 2.0 controllers but I'm afraid to install it since SP2 is already on board and I don't know what will happen. I really do NOT want to go through another reinstall of xp. I have a small form computer and I do not believe that there is room for a PCI card.

If you were able to install SP1 (and it is doubtful that you could), you would really mess up your computer. Try installing the motherboard drivers. If that doesn't help, then random problems like you are describing usually mean failing hardware. Check out the USB troubleshooting links I gave you. Your statement that there is no problem with "individual USB ports because they all work except when they don't" really doesn't make any sense. If they don't work sometimes, there is a problem. Whether you choose to 1) troubleshoot further; 2) replace the motherboard if warranted; 3) live with the problem - is your choice. There really isn't anything further we can do for you in a newsgroup. You might want to have a computer repair person take a look hands-on. Don't use a BigComputerStore/GeekSquad place. Get recommendations from friends and colleagues. Good luck, Malke -- Elephant Boy Computers http://www.elephantboycomputers.com "Don't Panic!" MS-MVP Windows - Shell/User
