My desktop ...suddenly developed a problem with recognizing the mouse through the USB port...puts up the error message:
"USB Device Not Recognized
One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message."
.... I tried that mouse on the laptop - works fine.
I tried the mouse from the laptop on the desktop - didn't work.
I tried a wired mouse plugged into the ps2 port - same message.
This happened when I attempted to download pictures from my camera, which I have done over a hundred times before.
Note: the keyboard works fine. I tried moving around with it, got to Device Manager. The entry for USB has the telltale yellow circled exclamation point.
....to reformat the drive....
Reformatting the drive won't help.
If the keyboard is a USB keyboard does it work in this USB port the mouse was in?
Will the nonworking mouse work in another USB2 port on this computer?
Did you try reinstalling the latest device driver for the mouse?
So the USB hub has a yellow flag but the Mouse does not in Device Manager?
I have other suggestions but I think I want answers first.
Make and model of computer or MB? Mouse?
