I have a toshiba laptop a215. When I first bought the laptop and an usb optical mouse everything was fine. It was fine every time I plug it in and out.
But after a few months of using the mouse it always says "USB DEVICE NOT RECOGNIZED". I Have read a lot of posts regarding these but none of them seems to work. I have tried tried Uninstalling and reinstalling the device in device manager. Tried Disabling and reenabling the hardware device. Tried Restarting the computer with mouse plugged in. Downloaded the latest BIOS(before was 1.0 now its 1.7). But none of these seems to work.

By the way, everytime I plug in my usb mouse there is always power. (Light is turned on)

I also recognized that in device manager my SCSI/RAID Host Controller has a "!" in it. Can this be the cause of the problem?
Also Under USB, when my mouse is plugged there is no "!" but it only says "Unknown Device"

Please help me fix these.

Hi leonmiguel, and welcome to BleepingComputer.

Have you looked in the BIOS to see if the USB mouse is enabled?

What do you see if you right click on the unknown device and choose the properties option?

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
