Neither Internal USB A/B HUB connections work. All external USB connections do work. The Internal USB seems not to be recognized, i.e., green power light remins dark, while when connected externally, the power light goes green at system start-up and during device activation time. Driver problems ???

does it all look fine in device manager?
Also on some computers in the BIOS/Setup you can disable/ enable certain USB sockets like having options of Front only/back only/both etc. They do not always offer these options

Make sure all the USB ports are enabled in the bios Setup pages - they are by default when the mboard is new.
You have probably connected to the mboard USB headers/connectors incorrectly.
The pinouts of the USB headers/connectors on the mboard were never standardized. There are several common configurations and many oddball configurations possible.
There are several possible kinds of wiring connector configurations for the front USB ports on the case, and for wiring adapter plates with USB ports in them you install at the end of a slot.
If the USB wiring adapter plate came with the the motherboard, or if you have a brand name system and the front USB ports and/or plate were already wired up, they will already have the proper wiring and connector configuration, but otherwise it can be a crap shoot whether the wiring and connectors for the ports on the case or plate can be used with the pin configuration on the mboard.You must consult the mboard manual for the pinouts of the USB headers/connectors on the mboard, and determine whether the wiring connectors you have for the USB ports in the case or on the plate adapter can be placed so that they are connected properly.
The only situation that is universal is if each wire from the case or plate adapter has it's own female connector. Another confifiguration that often works is if all the wires have their own female connector except for the data wires which are in a dual connector (one dual per port).If they have two 4 or 5 wire female connectors on the wires, they will not work on some USB headers/connectors on the mboard, or they may have to be installed in opposite directions rather than the same direction. Single double row female connectors for both ports may or may not be wired the same as some USB headers/connectors on the mboard even if they will physically fit on the header/connector pin arrangement.

This is a "standard" unmodified virgin INTEL D945GNT/PSN MB with unmodified latest update BIOS release level. All external USBs are operational, i.e., any device can be plugged into any USB port and will operate identically. I have an internal 45-in-one card reader which can be plugged into any external USB port and operates identically from any other port. I want to use one of the USB ports (A/B) from the USB Hub located on the MB and described on the Intel MB schematic. Intel documentation says this internal USB MB Hub can be expanded to 2 external ports (front or back). I plan to expand it to an internal 4 port Hub (non-PCI). However, in the meantime, I am assuming that I can use it as a single internal USB port (which is what this is all about). Now that I think about it, that may be where the problem lies. Is the USB expansion circuitry necessary for this to work?
The Intel MB internal USB Hub pin geometry (4/5 pin setup, clearly visible on the MB) is pretty straight forward and as far as I can see, can't be mispositioned because of the relationship of the A(4)/B(5) pins on the MB.
The BIOS only has one thing that can be changed, as far as I could determine, USB 2.0 can be turned "off" or "on", in which case it reverts to the old v1 which is still on when 2.0 is off and vica versa.
The only thing that bothers me about my conclusion above, is the Int USB Hub expansion comes after the MB Hub, and since the device is not even queried now, when would it ever get recognized? How would I test for a live USB Hub? It seems to be dead as of right now!John O. Rem

I looked at the manual for your mboard - the Technical Product Specification
Layout of mboard connectors on pages 12 and 13 of the pdf
BB - USB - two ten position, 9 pin headers/connectors
GG - IE1394A (firewire), nearer to the PCI slots - two ten position, 9 pin headers/connectors
page 66 of pdf
Front panel USB Connector and Front Panel IE1394A connector have exactly the same pin arrangement!If you have the optional IE1394A connectors, they look identical. Make sure you are using the right header/connector(s)!
If you plug in a USB device into the IE1394A connectors, you can fry the IE1394A circuits AND the USB device!
.......You are confusing terminology.
"...this internal USB MB Hub..."
Technically a USB Hub is two or more USB ports that connect to one connection to a USB controller. The USB headers/connectors on the mboard are not Hubs - each of the of 2 USB ports connects directly to the USB controller, on each of the two USB headers/connectors."I plan to expand it to an internal 4 port Hub (non-PCI)."
If it is an adapter plate that installs at the end of a slot space and the ports in it are accessible externally and it connects by its wiring and connectors to at least 8 of the pins on one mboard USB connector, it is not a Hub, it is just an adapter.
It is a true USB hub if it is four USB ports which connect to one USB port or only 4 pins on one of the mboard USB headers/connectors, only the one port plugged into is directly connected to the controller.
The problem with true USB Hubs is they don't work with all devices, and unless it is a USB hub that also has a power pack (a powered USB Hub) the max 500ma available from the one USB port it is plugged into is shared with all the USB ports in the Hub. Some devices will work without the Hub having the extra power, some will work in the hub only if it is a powered Hub, but some devices just won't work in a Hub - they must be be plugged directly into a USB port that connects directly to a USB controller.
......"Is the USB expansion circuitry necessary for this to work?"
Not unless you need more than the total of 8 directly connected to the controller USB ports. If you do need more that are directly connected to the controller, you get a USB controller card and install in in a PCI slot.

"If you plug in a USB device into the IE1394A connectors, you can fry the IE1394A circuits AND the USB device!"
If you just plug in a USB wiring adapter female 4 or 5 position connector and a USB device has not been plugged into it, no harm done.
There is no connection on pin 10 of the USB connectors - a 4 in a row USB female wiring connector or a 5 in a row USB female wiring connector with 5 wires and 2 ground wires on one end (the usual case) will work on these connectors.
A 5 in a row USB female wiring connector with 4 wires and no ground wire at the 4th position will not work.

Thanks very much for spending time on this. I appreciate it and know that you have better things to do. The following is what I have in mind [photo of 4 port internal USB 2.0 device]:
http://img72.imageshack.us/img72/50...
I have been following the discussion in "thebestcasescenario" forum. As far as I can tell, I should be able to hook this device up to my Intel motherboard "and go". But, if I can do that, why can't I just hook a USB device directly up to the motherboard "and go"? I have already asked Guttenaffe for a quote (which he e-mailed back) and I said I wanted to go ahead with the project. He has not replied. The result is that I tried the direct hookup (failed as you know) and now I'm wondering if this failed, would the 4 port device fail also? Is it my motherboard or what and how can I be sure? Thanks.John O. Rem

I do have 1394A connector pins on my MB, and yes, it is close to the USB pins. But, no, I didn't try the 1394A hookup and as far as I know it has never been used except maybe in manufacturing Q/A. The card reader has a 5 pin connector and I did put it on the USB 5 pin set.
I have reread your comments on terminology and will try to clarify that in my mind. I have been on the Intel Web page a few times in the past and have examined their MB photos. I will specifically look up your references and make sure I understand them. Any questions I have will have to remain a puzzle since I have found Intel to be completely unresponsive, unless one chooses to pay for the answers. Again, Thanks. JohnJohn O. Rem

You shouldn't need to go online to look at a picture of the connectors on your mboard. If you have the CD that came with the mboard the manual - Technical Product Specification - D1406901US.pdf if it's the same as it is online - is on the CD in .pdf form, and it may have been installed on your hard drive as well when the mboard was originally installed. Intel often also supplies you with a physical printed version of the manual as well when you get the mboard new.
If you have EVER reloaded Windows from scratch on this computer, you MUST load the drivers for your mboard after running Setup in order for Windows to properly recognize the mboard and the USB controllers - if you have not done that or you're not sure that was done, load the mboard drivers as soon as you can. The drivers for the USB controllers are built into Windows, but to be sure Windows has the right information Windows must be informed of what specific type they are by the mboard drivers (*.inf files for USB in this case).
Use the driver install on the mboard CD if you have it, or go to the Intel site and get them for your model.In order to support USB 2.0 controllers or USB 2.0 true hubs like the one in your picture, XP must be at least SP1 - if you have an older XP that does not have at least SP1 built in, you must update Windows to at least SP1 - these days most people upgrade to SP2.
If all your mboard USB controllers (including the ones that are already physical ports) are enabled in the bios and working, when you look in Device Manager (e.g. RIGHT click on My Computer - Properties -
Hardware - Device Manager
under Universal Serial Bus controllers
you should see 4 controllers, 4 root Hubs (that's what 2 ports directly connected to a controller are called, a different situation fron an add-on hub), and,or including, at least one entry to do with USB 2.0 (I'm looking at a computer that doesn't have USB 2.0).From that picture link -
- I looked up the main chip and it's a HUB chip, not a USB controller - the USB female wiring connector from it must be connected to the proper pins on the mboard header connector - it is not a stand alone device.
It has the limitations I mentioned before that all true hubs have.
- from what I can make out the female USB wiring connector looks like it has 5 wires in a standard order, the fourth black ground wire in position 4 - it should work fine connected to the mboard header/connector as long as the first 4 wires red x x black are connected to the proper pins in each row on the mboard - red going to +5v DC - the +5v pins are on the end of the headers/connectors that DO NOT have a pin missing.Similarly, if you have a USB wiring adapter with a plate with ports in it, as long as it has the standard order of wires like for the hub in the picture on the female wiring connector, it will work fine if you connect to to the proper pins in each row on the mboard - red going to +5v DC - the +5v pins are on the end of the headers/connectors that DO NOT have a pin missing. Most USB wiring adapters are just wiring - no chips or components involved - certainly no chip with a large number of leads.
....Whenever you do anything inside your case, you should always disconnect the power to the case by unplugging it or otherwise removing the power. ATX power supplies are always powering ATX mboards in some places even when Windows is Shut Down or in Stanby or Hobernate modes. If you don't remove the power to the mboard, you can damage circuits or devices while plugging in or unplugging connections or cards.
The manual says the +5vDC connection on the headers/connectors is fused. If that pin has ever been shorted to ground or whatever, the fuse (one for each 5v pin? - 4 of them?) will blow. It may not be obvious what the fuse looks like - it is likely somewhere near the headers/connectors and may be very small and not look like a typical fuse at all. If you have a voltmeter you can check for 5vDC by touching that pin with the + lead, and having the - lead on the ground pin of the 4 in the same row.
......"I do have 1394A connector pins on my MB, and yes, it is close to the USB pins. But, no, I didn't try the 1394A hookup and as far as I know it has never been used"
Has anyone else owned this computer?
If so, they have have blown fuses for the 5v on the headers/connectors.
