Front USB Ports

Antec has made the blocks that hold the wires for the front
USB ports so the wires can be moved around within the block.
Apparently, there's [at least] two common configurations for
the USB wires/signals - and they are not pin compatible.

I think that is a silly idea.

Lastly, from usbman website:
"It is imperative that the specific USB pin out assignment for
your motherboard make and model is obtained from the maker
before any attempt is made to connect the cable to the
motherboard. Simply knowing which pin is #1 is not enough
information to properly wire a USB port. Trial and error will
surely result in the destruction of the USB host controller, the
computer system and/or any attached peripheral. YOU MUST obtain
the exact USB pin out assignment from either the motherboard
manual or the manufacturers web site."

I would look for a better source of information.

I've got my new box built, OS installed, and everything's running sweet,
except for the front USB ports on the case.

Case: Chieftec (Chenming) Bravo Series
Mobo: Asus A8V Deluxe

The mobo has four onboard ports, which work fine. It also has two dual
headers for additional ports. Plugging the cable from the case into the
header, the USB ports (only on the case) don't work. The mobo also came
with another dual port that can go into the back, filling one of the
expansion slots on the case. This dual port works.

Googling has led me to believe that the pin setup isn't in sync. The
schematics from both the mobo and the case, however, appear to match up.
The case also has audio, mic, and 1394 ports on the front. The audio and
mic work; unfortunately, I don't have any 1394-compliant devices with
which to test.


Has anyone run across this before? What tends to be the cause of this sort
of problem?

Worth checking on Chieftec website. I had problem with my front USB - MSI
KT6V LSR motherboard & Chieftec BX midi case.
The pins on case were correct number but not in right position form
motherboard - had to split 3-block pins with modelling knife into seperates.
Details on pin assignments for cases are on website.
