Solve : Help! USB mouse suddenly not working?

1.	Solve : Help! USB mouse suddenly not working?
Answer» I am using windows vista 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 got it fixed! I read somewhere about removing the battery, power, and holding down the power button for 30 sec.
