-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've been having intermittent failures of the USB ports on the back of my 17" Studio LCD display that has the ADC connector. Finally called AppleCare and they had me reset PRAM and then boot into Open Firmware (hold down cmd-opt-o-f on restart). That led to a bunch of USB errors being generated and replicated the failure of those USB ports. (I've kept a card reader that has a green light pugged into one port so I can see when I've got problems...) The tech had me type reset-nvram and then reset-all which rebooted. So far the problem hasn't happened again. I may take the monitor in anyway since I have less than a week of AppleCare coverage left. The tech left and spoke to his manager about the problem and came back and told me that it is very likely the display that is causing the problem. This is a known problem. If you got AppleCare on the display I'd take it in just in case. Regards, Joey Kennedy.
