[QUOTE="BumgarnerS, post: 542764, member: 43065"] Our household has two original Mac minis. When checking "specs" under About this Mac on one, the USB bus speed is identified as "high-speed" (for peripherals plugged in to either port) and the other is identified as USB bus. (There is a listing for "high-speed" on the suspect machine but the mouse and keyboard are not listed under it.) The one with "high-speed" allows USB 2.0 periphs to operate but the other does not. For the suspect machine, I first reset the PRAM with no change. I then reinstalled OS X Tiger and there is still no change. Suggestions? Thanks. [/QUOTE]
