I seem to have five different types of USB port on my G4 setup: 1) two ports on back of the CPU, 2) two ports on the keyboard, 3) two ports on the back of my cinema display, 4) four ports on a powered D-Link hub, and 5) four ports on an unpowered hub. I'm beginning to think that all of these are different. The easy example is that some devices won't work on the keyboard ports or the unpowered hub, presumably because they draw too much power. But I also find that the Tiger loses track of ports with varying frequency, so that I often have to unplug and replug my scanner and palm in order for Tiger to detect incoming signals from them.
I also believe that Tiger has a much worse problem in this respect than Panther or Jaguar. Since upgrading to Tiger, I find that I can no longer keep my keyboard plugged into the back of my cinema display, for example. That worked fine under Panther, but Tiger loses track and gives me a frozen cursor.
