AMD Zone has confirmed that a glitch in the dual MPX chipset, in particular with the 768 Southbridge, can cause difficulties using USB 1.1.
The Web site has confirmation from an AMD representative of the problem, which has caused some mobo makers to delay shipping dual boards.
AMD says the problem is minor but nevertheless is fixing the problem as a matter of urgency.
As we reported at the time, some mobo makers - such as Asus - are shipping USB 2.0 cards with their boards as a workaround to the problem.
