    Since upgrading to 10.4.3, my left USB port has been acting strange when I'm using a USB mini-hub. The hub works on the right port though. Rebooting the machine would sometimes work, sometimes it won't, and would take another reboot before it sees the hub. In the event that the hub is not recognized at start-up, connecting a single USB device to that port after removing the hub does not work either. I've tried resetting the PMU, but that didn't solve my problem.

    Anyone know if 10.4.3 changed power management settings? I'm thinking maybe less power is going to the port - if I connect just the mighty mouse before booting the computer, then it sees it.
