scheme to connect front panel USB-audio to USB port !!!? help meee!!!

The USB port scheme is this like:

sv.
pow. dy-dy+GND
4 6 8 NC
2 . . . . .10
1 . . . . nopin9
3 5 7
pow dx-dx+GND
sv

On the other hand i have for individual pins from USB-Audio panel
1.) port- 2.) port+ 3.) + and 4.) - pins.

How to connect this four pins on USB port. ???

When I'm not sure, I use a multimeter set to "ohms", to buzz out the
wiring harness. One probe of the multimeter, goes to a contact within
the external USB connector shell, while the other probe touches the wire
harness inside the computer (inside the black square plastic shell, to get
to the contact). The meter "beeps" when it finds the pin that matches
with the one I'm touching on the outside of the case.

This requires fitting "needles" on the end of the multimeter. I mean, these
probes are close to doing the job, but I fitted actual needles, so I could get
inside tight spaces (without having to puncture the wire insulation).

Sure, "+" could be VCC or +5V.

And "-" could be GND or signal ground.

But the multimeter allows me to be absolutely safe.

If you reversed the (+) and (-) for example, your iPod could be
damaged. Better to leave the front panel disconnected, than to risk it
if you aren't sure. In fact, on my current computer case, the front
ones aren't wired up.

The pin header descriptions above are a standard arrangement for a 2
port USB pinout.


Your front panel connector, though seems a little odd.  Is it a single
1x4 connector, or are they a individual plugs?

What is the manufacturer and model of your computer case?

 > How to connect this four pins  on USB port.  ???

They would (I guess) connect as follows:

1) port- . . . . . . DX-
2) port+ . . . . . . DX+
3) + . . . . . . . . +5V
4) - . . . . . . . . GND

This assumes you're going to use the USB PORT "X" row.  You could also
use the USB PORT "Y" row, just keep all 4 of your front panel plugs in
one row on the pin header.

Hi to group!

thank you for responding to my ask.post.

Yes, it's a 4 pin every per se.

It's MS Industrial computer case medium size.

the USB front panel has two USB entrances and two audio plugs(mic, and
something else...)


I'll ty this out with Paul's testing advice and reply tommorow, or if
i was burnt out, my mom or brother will make an grief notice.

And the Thanks-MuchAppreciated-WholeLotofThankYouAndThanks,
thankyouverymch,goes to Grinder and his help-assistant Paul!!!

Succesfully connected both USB ports, the scheme is valid for MS
industrial computer case.

Thank you !
