How are USB ports related to the computer power, and why would they cause my computer to freeze?

freeze

I have an issue with my new Toshiba laptop. Whenever I plug in an external USB device, if the laptop is not plugged in to the wall, the laptop freezes. However, nothing happens if the laptop is plugged in to the wall.

When I say the laptop freezes, I mean it really freezes. The only way to recover is to hard reboot.

My question is, what could be causing this? Could it be the extra power drain from the sub devices that causes this (even the simplest flash drives cause a freeze)?

Please help me out, it's very annoying.

Thanks
