Front USB 3 on pc case

If you have any bent pins, you need to find something to unbend it before plugging in anything. Very fragile
operation. If that is the way it came in the box and it is returnable then I would return it.

USB 1 = White
USB 2 = Blk ( any USB 3.0 plugged in goes into 2.5 mode )
USB 3 = Blue ( yellow often means always on and orange can mean high speed charge port )

In order for you to have USB 3.0 your board must have a separate bus specifically for that to function.
In the past if you plugged a lesser USB service on higher USB it would drop every other device on the BUS
to the lower-level USB 2 becomes USB 1. etc. USB 3 avoids this by going into 2.5 mode, and thus can be used
even on a USB 1.0 port.

PCi-X ( or it is PCi-16X ) have various modes and supports and you could install a USB3.0 card slot that
will always be USB 3.0 ( or whatever the kind ) to be used.

Why a USB 3.0 on the front? Because it was a selling point for that computer/board/labtop/etc. They placed
it there no different then any USB 1.0 slot via marketing so they could say "we have USB 3.0". Reality check is
that any modern computer should be USB 3.0 only ( with backwards compatibility with all USB types ) . and a
bus that will not drop in speeds. USB 3.0 speeds should move at 1Gig a second or more.

We even have 3.5 speeds nowadays. "Thunderboth" is being marketed as the end all i/o or whatever. But remember
things break over time

Yeah, according to that link I posted earlier, pin 19 isn't used.

I also see replacement USB 3.0 motherboard connectors in 19 and 20 pin arrangements. So 19 is what you have I guess.


Oops, that's pin 10, not 19 which is over current protection. It is discrete. Your bent pin is the USB differential wire.
