I recently installed Ubuntu 8.04 using the "install in Windows" option, and I'm having problems with my mouse and keyboard.

When I boot up in Ubuntu, the mouse and keyboard only work half the time. I have to boot in safe mode with the recovery console option to get it to work. It's weird, I can see when it starts in safe mode that it detects 5 USB ports sometimes, and when it does it detects the mouse and keyboard, but most of the time it only detects 3 USB ports. I have tried two different mice and keyboards, but still the same result. I updated all of the drivers and system files that I know of too.
