Strictly speaking it's a bus thing. Look at System Profiler...you'll see that each of your USB ports is a separate USB bus. Plugging a USB1 device into USB2 bus will slow down all traffic on that bus to USB1 speeds, so if you do have USB1 only devices (which, frankly speaking, are pretty rare) keep 'em segregated on their own USB port on your Mac. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
