I am using Windows XP Pro SP3
my mouse is an optical wired one, connected to the PC through a rear USB port.
The PC was running with no major problems.
This morning I found that the mouse indicating arrow was frozen.
After restart, I connected the mouse to another USB port with no success. I used another mouse, the same.
The mouse light (red light under the mouse) is lighting.
I try to use a memory stick (Disc-on-key), the light on the stick is on, but the PC cannot
detect it (even through the Device manager).
Above attempts were performed using the forward and the rear usb ports.
The Bios is showing the USB ports as Enabled.
I connected an old mouse (with the ball) using the standard round connector. I could finally use the mouse

Please asking for your kind assistance. What have suddenly disconnected all the USB ports "Data" connection
(I am using the word 'Data" connection since the light on all the devices is on i.e. current is passing through)

Microsoft recommends reinstalling the USB Controllers:

To remove and reinstall all USB controllers, follow these steps:
  • Click Start, click Run, type sysdm.cpl in the Open box, and then click OK.
  • Click the Hardware tab.
  • Click the Device Manager button.
  • Expand Universal Serial Bus controllers.
  • Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove them one at a time.
  • Restart the computer, and then reinstall the USB controllers.
  • Plug in the removable USB storage device, and then test to make sure that the issue is resolved.
Try this and let us know!

I've recently seen 2 issues with USB ports that were perplexing - especially since one of them was my main system.
Turns out the little black plastic thing inside the USB port on the computer was broken off at one point - then another attempt to insert a USB device caused the pins to short out.
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.

Work-around: http://www.newegg.com/Product/Product.aspx...N82E16815106505

I believe in always having at least one spare mouse, keyboard, USB 2.0 PCI card, and ethernet card...saves an awful lot of unnecessary frustration :thumbsup:.

I expanded Universal Serial Bus controllers (on the Device Manager) and right-click every device under the Universal Serial Bus controllers node,
clicked on Properties and got "This device is working properly" for every one

I restored my drive C to a previous stored state/date (backed Up ) when the USB ports were working.
The problem remain unsolved.

Is there anything else I can do beside 'changing my motherboard'?

thanks for assistance
