Default Do they make mobos with an internal USB port?

I have a USB port that mounts in a 5.25 bay and plugs into a USB port.
Do any mobos come with an internal port (not the pins)?

I don't know about MBs, but I've seen USB cards for PCI slots that have
standard USB ports as internal connectors (which I thought was strange at first).

?I've not seen a mobo with an internal USB port but that's not to say one
might not be available somewhere. On the other hand PCI cards are readily
available. I have a PCI card (4 ext+ 1 int) in an old build that I use for
testing. They are fairly inexpensive from Newegg, etc. but pci-e cards are
expensive. Could you just run a cable through an unused slot to a external
USB port on your current mobo.

Do I understand that you are looking to make your mobo decision based on
whether or not its USB will match your USB bay's connector?

Wouldn't it be better to make an important mobo decision based on more
important factors and 'adjust' for the USB connection discrepancy? There
are all kinds of ways to solve the 'normal' condition of the mobo having
pins for the USB.

The header pins on the mobo ARE the USB port. If an internal device
wants to connect to a USB controller, it should have the requisite
header connector to do so. The externally-facing USB port shouldn't
assume that you have a some rare motherboard that happens to have a USB
port on it instead of USB header pins.

Seems the unidentified USB drive bay unit was designed to plug into a
USB daughtercard that has an internal USB port; otherwise, the USB drive
bay might have a ludicrous routing of running its cable through a case
opening to go outside and then plug into a backpanel USB port (you lose
a backside USB port to bring it to the front).

Do you have a web page link to the so far unidentified USB drive bay?

Newegg's tool to help you see something well is really useful. Not only
can you look at the device up close, but you can even zoom in on the
box/packaging information and read it.

Considering how many items they must have in their inventory, that must
be quite an undertaking to catalogue and 'connect' all that data and images.

Nice catch.

I didn't know they made something like that.

*******

Motherboards can have up to three 2x5 pin headers, giving
up to six internal USB2 ports available. The only thing
you'd have to watch for, is whether that Koutech gadget will
conflict mechanically, with anything in the vicinity. For
example, if you installed three of those stacks, you might
have problems routing cables. With only one of those
installed, there shouldn't be a problem.

When you install a cable in that thing, you'll need to
tie wrap the USB cable to the adjacent drive bay framework.
That will be necessary, as the pin header has no retention
feature to hold it in place. To help support it,
it may help to take the strain off the cable, with
a tie wrap.

Some motherboard pin headers, have a supporting plastic
frame around them, while others use just the pins. It's
also possible there is some variation between motherboard
models, in how long those pins are. All should make
proper electrical contact, it's just some of them will
grip better than others. And that's where the nylon tie
comes into play.

*******

I checked the Koutech site, and can't find a pinout for the
connector on the IO-UU220. This page, shows some of the
variations possible. An older motherboard may use some of
the alternatives. What they don't mention here, is some
motherboards use "OC#" instead of "S-GND" on the odd pin,
and in most cases you wouldn't want to connect to it.
OC# is just a curse, because when you plug in an adapter,
ground touches the signal and the port shuts off in response.
OC stands for OverCurrent, and those motherboard designs are
prefaced on the adapter being responsible for detecting
an over current situation. Most motherboards now, use a
PolyFuse on the motherboard to protect the port, and the
handling of OC# is purely an internal motherboard issue,
hidden from the user. So a modern motherboard, doesn't have
an OC# pin.

http://www.frontx.com/cpx108_2.html

+5V +5V This is my assumption as to
D- D- what Koutech used for a pinout.
D+ D+ There are some odd-ball older
GND GND motherboards, where plugging in
S-GND this adapter, would shut off the ports.

The S-GND should go to the "metal can" of each Koutech connector.
The GND is a signal ground, one of the four USB connector signals.
In the USB cable, S-GND is what is connected to the metal shielding
around the cable bundle.

I will take it from the group the answer is no.

Using an adapter like this is a close second. I also have a PCI card
that does USB, but they are getting stingy with PCI slots now a days.
You only get two spots most of the time. A wireless network card and
a sound card are two things that haven't been replaced on the mobo
yet.

I've seen flexible cable versions of those do-dads as well.
