This has nothing to do with Ubuntu; a usb device is drawing more power from the ports that it should. For example, have you plugged in a USB hub without external power turned on? Or have you plugged in a single usb cable instead of plugging in two ends, if you have a "Y" cable?

no, my PC has two usb port.
i used one port for my mouse and one port's free.

on the text mode, my screen is flooded by these messages, i can't see anything and work on text mode.

Can you post the output of
lsusb from a terminal (Applications-Accessories-Terminal)? Or is that "flooded" too? If you unplug your mouse, do the messages stop?
