My friend just got a 1.25GHz MDD but he says he is having problems with it. He says that when he starts it up, his mouse light (sensor) flickers and the keyboard does not work. The only way to fix this is to unplug and replug in the peripherals. He also tried on his Studio Display connected via ADC and the same thing happens. Could a PCI USB card help his problems or is there some way to fix the current USB ports?
