2 All USB, internal and external do not work
It does not recognize the keyboard, trackpad or internal bluetooth.
When I connect an external keyboard or mouse does not recognize it either. If I connect a flash drive does have power (the LED lights flash drive), or connect a mighty mouse also has light, but the MacBook does not recognize either the mouse or pendrive.
In system profile it does appear the USB controllers, but no device recognized, and if they produce energy, because if I connect a USB flash drive or a lamp, or a mighty mouse do the LEDs that light up for the devices. But for the system, both the boot and Mac OS X or Windows (bootcamp) not recognize it.
If I connect to macbook by remote desktop, keyboard and mouse that I have, obviously, or use a program to control the mouse from the iphone via wifi also works as logitech touch mouse Touch Mouse
I can not reset the pram, nvram, or anything that needs to press something before you can connect through remote desktop or touch mouse.
Airport works, external display works, sound works, termal sensor works, fan speed works, battery and macsafe works, I can't to know if firewire works sorry.
Any ideas?

The laptop I have now retired, but I put the info in case it is useful to someone.
After upgrading to Snow Leopard, the installation had to reset the SMC, PRAM or update any firmware. Magically began operating the internal USB ...
Now it all works internally: camera, bluetooth, keyboard, mouse ... But the two still do not recognize external usb devices.
