Does anything else work in that same port?

by wanttocancel In reply to win xp usb problem

If not then the port on the mobo may be bad. A reinstall of software won't repair that; only a new mobo can. (Or possibly a powered usb hub.)

no ! nothing works in any of the 5 usb ports on the mobo, I have uninstalled and reinstalled ,to no AVAIL , I have not exprerinced this before,usually uninstall and a reboot corrects the problem.

See if this is of any help

The quickest fix would be to install a PCI USB 2.0 Controller Card but you can also run these tests.
Here is a link to a handy little tool. Save it to the desktop.
Using Intel USB System Check<br>
After the download has completed, browse to the file usbready.exe and double-click it. A Welcome to Intel USB System Check message will appear on the screen. <br>
Click Yes . The Intel USB System Check program will check the computer system for USB compatibility. <br>
Computer systems with full USB support <br><br>
If the computer system has everything required for USB to function correctly, a ?This system has full USB support? message window will be displayed. This message window has green squares with the word "YES" in them.
Computer systems without full USB support <br>
If the computer system does not have everything required for USB to function correctly, a ?This system currently does not have full USB support? message window will be displayed. This message window has red squares with the word "NO" in them.<br>
Click Details, and then read the following summaries that are displayed: <br>
System Software Support<br>
System Hardware Support<br>
USB Driver Support<br>
Check Capacitors around the CPU for swelling or bulging.
As the capacitor ages, its capacitance decreases while its equivalent series resistance (ESR) increases. When this happens, the capacitors no longer adequately serve their purpose of filtering the direct current voltages on the motherboard, and system instability results. Some common symptoms are:

* Not turning on all the time; having to hit reset or try turning the computer on again
* Instabilities (hangs, BSODs, kernel panics, etc.), especially when symptoms get progressively more frequent over time
* Vcore or other system voltages fluctuating or going out of range, possibly with an increase in CPU temperature as the core voltage rises
* Memory errors, especially ones that get more frequent with time
* Spontaneous reboots
* In case of onboard video cards, unstable image in some video modes
* Failing to complete the POST, or rebooting before it is completed
* Never starting the POST; fans spin but the system appears dead

Test the Power Supply Unit and the CPU.
Download Prime95.
Prime95 is used to put your system at full load. Prime95 - When run for the first time, it is necessary to click on Advanced, then click on Round off checking so that errors caused by instabilities will be flagged as they occur. Also go to Options and run the Torture Test. Run the Inplace FFTs (Max Power, Heat and some Ram). Prime95 will automatically thread all Cores, and will expose insufficient CPU cooling and computer case cooling, or excessive Vcore and overclock. At no other time will a CPU be as heavily loaded, or display higher temperatures, even when OC'd during worst-case loads such as gaming or video editing. Prime95 can be used with SpeedFan to observe CPU temps, while stress testing for system stability. During single threaded gaming and applications, Core 0 typically carries heavier loads and higher temps than other Cores.
You want your system at full load when checking your voltages to ensure your PSU is up to spec.
If your PC restarts during this test you have a faulty Power Supply (PSU) and it will need replacing.
Download SpeedFan and check the Voltages and Temps while Prime95 is running.
You will want your 12-volt rail to be within 11.52 to 12.48 during load. This means when you are running your cpu at 100% you do not want to drop below 11.52 or you may experience stability problems including but not limited to system restarts and Windows crashes. For the 5-volt rail, you want it to be within 4.8 to 5.2 to be within the 4% range. As for the 3.3 volt rail, you want it to be within 3.17 to 3.43
