iMac USB ports

I ran into an interesting problem recently. I have an intel iMac (17" 1.83 GHz Core Duo, ordered the day the became available), that is out of AppleCare. Recently, my keyboard and mouse quit working. After some fiddling, I determined the problem to be with the USB port. By plugging the keyboard into a different USB port (the mouse is plugged into the keyboard) everything started working again. I can plug other devices into the other USB ports and some will work, but some (including the keyboard and mouse) will only work in one of the 3 ports in the back of the machine.

I'm not really looking for troubleshooting, but more some general advice from anyone who might know:

1. What kind of repair cost would I be looking at to get this problem addressed?
2. Would I be better off to go buy a USB hub and plug it into the one working port and plug all my devices into it instead, hoping that last port doesn't go the same way the first two did?

Get a USB hub. The USB parts are a part of the logic board and changing out the logic board for a new one out of warranty costs more than your iMac is worth, even if the ports weren't defective.

It would seem to me like it is a power issue. To repair the logic board is very expensive - you'd have to purchase a new board, in the range of $900.

I'd suggest a USB hub as a solution.

Thanks guys, you've both confirmed my assumptions, but it's always good to have a second opinion. I guess it's off USB hub shopping I go.

Make sure to get a powered USB hub, so as not to strain/overdraw the final port.
