USB ports erratic on winXP

libskrap
on various desktop pc's, the USB ports (used for printers and keyboards, primarily) either work erratically or stop working. the problem is for those ports only, and solved by moving the device(s) to another port. the first port is essentially dead, as it cannot be used for anything else. These are white box pcs, and work flawlessly in every other way.

Has anyone encountered this? Is there a fix, or do the ports just wear out over time?

Thanks.

    Their solution was to shut down unplug the computer for several minutes and then plug back in and and reboot. Don't ask why but it does work and cures quite a lot of the USB problems that where introduced by several of the Windows Patches.

    I used a rear USb port for my printer connection and recently it failed to link with the computer. Subsequently when used a fron USB port it began to work.
    Can any one explain why the rear USB port failed. I am using Win XP OP.

    Are connected to the M'Board.

    If they are on a fly lead and connect to a Header Pins on the M'Board they have less power available to them than the ones that are directly soldered to the M'Board or may not even be connected properly if at all.

    If they are a direct connection to the M'Board and do not work you need to look at the available power or USB Drivers and maybe the number of Enabled USB ports in BIOS.

    Depending on the M'Board maker you can have several different USB Ports in the back of a computer that connect in different ways and some of these particularly the ones on Fly Leads can be disabled in BIOS to preserve power or make the original installation easier as they do not require specialized drivers that are an extra to the Windows Drivers. Sometimes these extra ports are not enabled and fail to work because of this and other times this results from a lack of available power as the M'Board can be over taxed when many USB Devices are connected and sucking power out of the system.

    It's also possible that whoever setup the system failed to properly connect extra USB Ports that are on the back of some computers again this is directly related to the M'Board used.

    What you need to post is if this Port worked previously and is now no longer working or if this was a new installation that failed to work. The answer for both of the above possibilities is completely different.

    I have tried several things for this issue. Unplug all but essential USB devices, get the USB drivers for the system and uninstall/reinstall the ports.

    Oh yes and I have tried unplugging everything; unplugging essential USB (mouse< keyboard), and nothing is helping.

    Often the MB chipset driver houses the USB drivers.
    Update your BIOS and reload the chipset drivers.

    and reboot without any usb devices attached.
    i expect somebody already mentioned this.

    Where exactly does your system stop booting? Is it before Windows loads?
    If so, you may have other problems.

    When it stops, does it ask for a boot or HDD password? Does your keyboard work at all? Please list specifics

    It does stop booting before Windows loads. Last night I was messing around with it and it said "BOOT failure. Insert BOOT disk into Drive A:" I now know it is not my USB ports not working. My keyboard works since I plugged it in as a PS/2 port. I normally would hear the fans and (I call them drivers) start up, but not with this problem happening. IBM can't help because they no longer support it. THANKS!!

    Not being present or at least not being able to be read so that you can load your OS.

    The first thing to do is open the case look at the HDD and find it's brand then download the Drive Makers Testing Utility if this is an IBM that should be from Hitachi and test the drive. If it fails the test plug in into another computer and test again. If it still fails the test the HDD is faulty and needs replacing but if it passes in the second computer the HDD Controller on the M'Board is faulty and needs replacing or at the very least the Data Lead that connects the HDD to the M'Board is faulty and needs replacing. Unless the leads have been pulled on they do not often fail so I would be looking at either the HDD or the M'Board as the most likely culprits.

    If you don't have another computer to test the drive in get yourself a copy of the Ultimate Boot CD and run some M'Board Diagnostics as the Computer boots from this CD and it's available for download here

    I've had this problem since I installed Windows XP home edition. At first I would have a message come up on startup saying that my USB device is not found, but if I hit ESC I could resume and everything would be fine. Now I can't even get my computer to go past startup. My tower is an older model (IBM Aptiva with an Athilon processor), so it doesn't have the extra USB ports in the front like the newer models. I unfortunately am running out of ports that I can keep using; I'm on my last workable port.My keyboard and mouse work off of the USB ports, but I could buy the adapter to switch to the PS 2--if I REALLY have to.
    If there is a fix or a possible solution I would like to know also. I can't really afford to switch my computer system at this point. HELP!!!!

    I too get machines where the keyboard and/or mouse sometimes just freeze. On a Dell Optiplex GX620, when I create an image with either Win2K or XP, I usually plug the keyboard and mouse into one specific place, there are 2 rows or USB ports, one with 4 one with 2 ports, I use the row with 2 ports and plug the mouse in on top and the keyboard on bottom in the same row. After I create the image and another tech deploys it to a new user on the floor, the keyboard and mouse are not always plugged back into the same ports that I used to create the image with. When the new user logs in, a msg says New Hardware found but the user can not install the drivers becasue they do not have permissions to do so. With out granting admin rights to the users or plugging the keyboard and mouse into every USB port on the machine and letting the machine find it each time, how can I get it to auto install the drivers for any port the keyboard or mouse is plugged into? This also happens when the keyboard or mouse freeze up in whatever USB port they are in, and the fix is to move the keyboard to another port but then they don't have rights to install the new hardware....

    I have found that using a good, external, powered USB hub allows the USB connected devices to work normally. The direct connection to the pc still continues to fail. So, it seems that the signal strength of the internal USB connector is the issue. The external powered USB hub seems to be the key. Next step seems like having the pc makers put more power (or more consistent power?) in their internal USB ports. The software side was not an issue.
