it is an optical mouse, i have actually tried connecting the mouse to other pc's, and it wont work, so i guess its gone. i dont see why the bios setting should change just by connecting a usb device, is it even possible for all usb ports to get destroyed like that?

Have you tried this:
My Computer > Properties > Hardware Tab > Device Manager > Expand Uninversal Serial Bus Controllers > Right click all "USB Root Hub" entries > Power Mgmt tab > Uncheck "Allow the computer to turn off this device to save power."

To clarify a bit - short power line to data line and you will kill the ports and any devices attached at the time.

i would test the flash memory on another PC to be sure it's working. When you say it does not work, what do you mean? any error messages, or nothing at all ?
Other than that, you ca,n try this :
In regedit navigate to : HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
Delete All of the \DosDevices\ ... values corresponding to external usb drives/keys/thumbdrives etc
reboot and test
