I have been unfortunate enough to have TWO motherboards blown because of a power surge through a USB device. The first time it was the devices fault, a crappy .mp3 player that had a AA battery in it caused instant computer death. The second time it was my fault because I messed with a battery on
a device while it was plugged in.
If all USB ports had a small circuit breaker like those found in christmas tree lights it would be all but impossible to blow the motherboard. They would have to be replaced if tripped but that is a lot easier than replacing the whole motherboard.

Hm... never had that happen to me. Surely these exist, it sounds so obvious. Have you done your homework before posting, Matt? I'll be doing a little browsing of my own, and I hope I don't find something like this on a simple Google or Wikipedia search. |

[link], if there's a fuse for the purpose, then surely there's a motherboard out there which uses it. |

Spacecoyote's link is probably more on the mark, but I found some USB port surge protectors that would accomplish the same thing. Gotta Google, dude. |
