my mac book doesnt read any usb

So no USB devices work with the MacBook, in any USB port, is that right?

Open your System Profiler by going to the Apple menu > About this Mac > More Info... > System Report (older versions of the OS may be slightly different) and under Hardware select USB. Do any connected devices show here?

If not, try resetting the parameter RAM, and if that doesn't help, resetting the System Management Controller.

Best of luck.
