None of my USB ports are being recognised or working.
Hello,I'm not a very advanced user but I rebooted my computer a few months
ago because I suspected some kind of virus. I found subsequent to rebooting that none of my USB ports would work or be recognised in My Computer. Any help would be gratefully recieved. Thanks. Will. |

Why did you suspect a virus? What symptoms did you have? Do you run an anti-virus program? Did it tell you that had a virus? What virus was it? After you "rebooted" (or reinstalled Windows) did the virus go away? How did you know? I found subsequent to rebooting that none of my USB ports would work How do you know? Please explain exactly what you did and what the results were. If you got an error message, please quote it verbatim. ... or be recognised in My Computer. "My Computer" never recognizes USB ports. It does recognize drives that are plugged into USB ports. Again, please describe exactly what you did, what happened, and what you saw. Any help would be gratefully recieved. Please answer the questions above, and I'll try to help. -- Ken Blake, Microsoft MVP (Windows Desktop Experience) since 2003 Please Reply to the Newsgroup |

There is one hardware chip that can actually have all its USB ports fail at the same time. That is the Intel ICH5 or ICH5R Southbridge. So it can be explained as a hardware failure. To identify that case, I'd need to know the make and model of computer or of the motherboard inside the computer. The USB driver comes with the OS, and USB2 would be present if you had at least WinXP SP1 service pack. http://www.usbman.com/USB%202%20News.htm "Microsoft Win XP USB 2.0 drivers are included in Service Pack 1. Microsoft Windows 2000 USB 2.0 drivers are included in Service Pack 4. " You should check Device Manager, and look in the "Universal Serial Bus" section near the bottom. Some examples here. What these entries show, is the hardware inside the Southbridge. This is not a listing of "ports" but of the logic associated with USB inside the Southbridge. http://www.usbman.com/Guides/checking_for_usb_2.htm There is a utility that can show things plugged directly into your computer USB ports. You can get a copy from one of the dated links on this page. (UVCView.x86.exe) Microsoft used to offer this for download, but removed it. The archive has a copy of it. http://web.archive.org/*/http://down...VCView.x86.exe In this screenshot, you can see three "Device Connected" entries, and the data from one connected device is shown on the right. This is from an earlier version of the utility. http://www.die.de/blog/content/binary/usbview.png Paul |

If the OP reinstalled Windows (rebooted???), maybe he hasn't installed the chipset drivers and that caused his problem, just a guess. |

Go to Device Manager and look under USB devices. Are there any yellow exclamation marks? |
