Before you drop the mouse, check this short list.

  1. Have you checked this mouse on another pc?
  2. Have you checked another mouse on this pc?
    I ask these questions because your long sentence left me a bit unclear.


  1. Does your machine have multiple USB ports (most have),
    and, have you checked the mouse on different ports?
  2. Have you checked other USB devices (like external drives of large flash drives)?
  3. You could give a short try to this Microsoft KB article
    (it may not be necessarily related, but no harm checking),
    USB port may stop working after you remove or insert a USB device

hi nik its happening to all the mouse and this is a motherborad or windows xp error ,and all these mouse work fine on other pc's and ya since you have mentioned i have 4 ports the problem is that also only two usb work's at a time like if mouse and keyboard are plugged in and i insert my portable hard disk then mouse goes off – manpreet Aug 19 '09 at 6:21
sounds to me like some kind of power-to-usb issue. Could be that the actual wiring isn't conncted properly from your USB ports to the motherboard, causing faulty USB-functionality – pavsaund Aug 19 '09 at 7:48

@manpreet, Is your external hdd externally powered or using USB power? You could check with an externally powered USB hub. I agree with Pavsaunds comment. And, do get a good hub (its for power not extensibility). – nik Aug 19 '09 at 10:01

Have you checked this? Right click on the "My Computer" icon Select properties Select hardware Select device manager Open "Universal Serial Bus controllers" (near the bottom) Right click on "USB Root Hub" & select properties Select the Power Management tab Make sure that the box for "Allow the computer to turn off this device to save power" is not ticked. Do this for each USB Root Hub on your PC

Had this problem with several of our older Dell machines.Easiest solution was to buy inexpensive 4 or 5 port adapter cards and not worry with onboard ports.

Is there something special about this mouse? It sounds like a connection problem (dry joint or similar), and unless it's a high-end mouse, it may not be worth your time debugging it if other mice are working and it can be replaced.
