It is possible that your USB ports do not match the speed of the USB devices you are using. For instance, your USB ports might be 1.1 ports, while the drivers you are using with your mouse and keyboard requires a 2.0 port. If that's the case, then your system is going to have trouble working with those devices. If that is the problem you're having, then the best solution is to either upgrade your motherboard or get a USB hub that can upconvert your USB ports to a 2.0 speed so your devices can work with them.
I am having USB port problems. Sometimes it works and occassionally it doesn't work. It has become worse since a few days. My mouse suddenly stops working. Is it a hardware or a software fault. I am using intel dual core 2.5 ghz on an intel DG31PR motherboard running windows xp SP2.
I even reinstalled the USB drivers(controller, hub), etc. But still the problem persists. It happens more when I insert a second USB device, then both the ports stop working. Then I have to remove and reinsert the USB device and it starts working.
It is really annoying when all of a sudden in the middle of a game, both the usb mouse and keyboard stop working
Somebody please help me out.
recently i discovered one more thing . when i plug in the speakers in the AC outlet on the UPS, both the USB mouse and USB keyboard hang.
does this problem have to do anything with the power circuit of the CPU
