I am using windows 7 and I've never had this problem before. My USB wireless mouse has worked perfectly for the past year. Suddenly, today, I discovered my mouse doesn't work anymore and it says:
USB Device Not Recognized--unknown device.
I thought, maybe my mouse is broken. So I plugged my mouse into another laptop (with vista) and it works! So my mouse isn't broken...I also plugged in a new mouse into my computer and the same error message comes up. This is strange...it sounds like something's wrong with my computer? What can I do?
I already tried rebooting it but that didn't solve the problem. i hv also done a system restore......
i have tried to plug in other usb items and it is not reading anything and this stupid thing keeps popping up saying it doesnt recognize it and nothing is plugged in

If other USB devices are not working...the problem is either the hardware or Windows 7 lost a driver.
To be cautious, assume something has gone wrong with the whole system. Maybe not. But be sure you have some kind of backup backup plan. Odd behavior sometimes is the only warning you get.
But most likely thing is the wireless mouse is failing for some reason.
Below is a similar problem from a MS forum.

One user over there thinks other USB devices might interfere. I really don't know.

Open Device Manager - any errors?

i fixed it...... not sure if i should have done it this way or not but it worked. I read somewhere to take ur battery out and hold the power button down for 30 seconds then put the battery back in and power on, it worked :) i hope it was ok to do????

Sure, it's fine. You just "cleared" the capacitors. Glad you got it sorted out. Thanks for posting back - and Happy New Year :)
