Case USB Connectors
I'm planning to upgrade a motherboard with one that has usb 2.0 and a front connector for two ports. My case has connectors for 2 front USB ports, but will they work with usb 2.0 in terms of compatibility?

aren;'t all usb headers the same for pinouts and stuff?
the pinouts are a standard... but manufacturers will implement them slightly different... mostly naming conventions.
Antec (case manufacturer) calls out the pins as USBD...
Asus (mainboard manufacturer) calls out the pins as USBP...
the standard is the same power, USB+ USB-, and ground

DeJimbo,
1. USB pinouts are standard for single rows but various mb makers either put the 2 rows of pins side by side maintaining the same order (1-4 or 5) for each row or reverse the rows so one row goes 1-4 and the side by side pins are 8-5
1 2 3 4 5 1 2 3 4
10 9 8 7 6 5 6 7 8
pins 1 and 5 or 1 and 6 are the same signal names. 2 & 6 or 2 & 7 are the same, etc based on whether or not you have a 4 or 5 pin header arrangement.
Somewhat Standard Color Code
Red = 1
White = 2
Green = 3
Black = 4 and 5

there are total 4 wires on one usb connector...but some connectors use 5 pin header for one.
this leads to chaos when u choose usb connector (for inside computer) so be sure abt it
