The mainboard comes with a JDB1 connector for you to connect to D-
Bracket™ 2, which supports both USB 1.1 & 2.0 spec.
D-Bracket™ 2 is a USB bracket integrating four Diagnostic LEDs, which use

16 combinations of signals to debug the system. The 4 LEDs can detect all problems
that fail the system, such as VGA, RAM or other failures. This special feature is very
useful for overclocking users. These users can use the feature to detect if there are
