02-superstar-[Looking for correct USB] 21st FEB-2007
Sorry I missed your signature Your photos/pictures did kind of mask it Usually I research your previous Posts for a quick interview, before answering the majority of my Post. But in this case It was just information that was asked for & I rushed it. I did a quick research, but not as thorough as normal.
I would have noticed your Post with SRX660 & Samm It was 120 Posts with 5,915 Viewers
Usually, I just look at their Posts, and dont step in. Today SRX660 had posted, as I was busy researching. and I did not realize he had past knowledge and a lot of input on this question.
I just wanted to emphasize the need to look at the Form & Fit
of Components before upgrading. Had I done my research as normal I would have known you were in Good Hands
and these were considered
Sorry for any confusion
One thing I noticed was that I went on a website for a random USB pci card and found this picture:
(This is a 5 port USB pci card using 4 external and 1 internal. But the diagram shows that there is a 2nd internal connection which I believe to be a "Pin" connection)
Ok This Card Pin/track Layout -
It was the 1st Card you listed as having an interest I gave you the Manufacturers webpage shown below And it was this website, that had this pin layout. Yes it looks like it has Male Pin Header Connector for a Single USB Port
You have 2 USB Ports & 2 separate USB Cables. So only one Port would be active
Also it has the VIA Chipset Now they may have improved their Technology But in the beginning VIA had USB Issues, related directly to the design.
Here is website that contains the Pin Layout of the USB Card that has the Pin Header Connector that supports a USB Series-A Jack/Receptacle
Model # 1066 (UPC # 833250001066)
5 Port USB 2.0 PCI Card (VIA Chipset)http://www.ppa-usa.c...sb_pci/1066.htm
Here is yet another random picture I found using google, of a random USB pci card. Notice how this one literally has pins sticking out of it!!!
CARD with Pin Header Connectors -
Do not know the website
This picture that is shown directly beneath the Pin Layout Picture [In your Pictures] is not the same card that Pin Layout is for. The Board picture shows 2 External USB Ports & 2 Fire wire (IEEE-1394) External Ports Plus 1 Internal IEEE-1394 Port And 1 Internal USB Internal Port - All using the narrow Series A Jack
Which always face Downstream
toward the device So the USB Cable would have to be Standard Detachable Cable
It would be terminated on the Upstream End
(Toward the Host) with a Series-A Plug
and the Downstream End
(Facing the Device) would be terminated with a Series-B Plug or Series Mini-B Plug
It also showing internal Pin Header Connectors for 1 USB & 1 IEEE-1394
As you pointed out But only one is for USB You need two One for each Front USB Port -
The Internal USB Series-A Jack could be used to provide power for a Front Panel USB HUB but would probably be considered a Low Powered HUB
because the HUB would be receiving its Power via the PCI BUS Unless they have separate Power Regulators for each Output Port You would have to read the specifications **Note on Specifications**
If it does not specifically specify an item Then that item is not in the specification
You can not assume The less that a device can perform the smaller the specification sheet -
Could this be the kind of card I need to be able to connect the front USB of my case? I have no idea if those pins on that kind of card is for what I'm exactly trying to do. Someone with expertise please help and if possible recommend a USB 2.0 pci card that can satisfy my needs. (Remember I just got these random pictures off google so I dunno where to get the right card)
Yes it could be But, this Card has both USB & IEEE-1394
Connectors for External Internal & Internal Pin Header Connectors You need to read the specifications to verify the support you require
You probably want to use the front Ports for your -
I need a "USB 2.0 Pci Card" so I can use my new webcam, external hard drive, and I Pod Mini. I have a few problems choosing the right one out of my two selections.
The Hard Drive unless you intend to travel PC to PC with You can connect to a rear port and leave connected You should purchase a Drive that has its own Power Pack [USB Ports are limited to 0.5 Amps-
] If you use this drive as backup then you should not use a USB HUB you want to connect directly to a PC USB Port Reduces Failure Rate
Lesser Components -
That leaves your WebCam and I-Pod Mini for your front USB Ports I would classify both of these as High Power Units and would recommend an USB-2.0 / 4-Port HUB with External Power Pack
that have LED for each Port & Power On indication Current limiting for each port with automatic reset
Regardless of what most people think or say USB still can have conflicts It is definitely minimized from the old Serial Bus but it is still a Serial Bus SO the WebCam can still have conflicts with your Video Card & the I-Pod can give you Audio conflicts They still require PC Resources
That when shared can conflict It is a lot better than before USB but conflicts can occur The IRQ Resources are usually automatically selected by Plug n Play
and are predetermined by PCI Slot Location The more expansion cards used the higher the conflict occurrence factor Also the order in which you install these Cards has a determination factor of IRQ selected The same is true with the Memory Range Allocation
USB states that it can support 127 devices Yeah good luck on that statement They didnt specify 127 Functioning Devices
Remember if they do not specify . . . . . . .
The more USB devices that were installed on a PC The differences in Manufacturing Technology began to separate the Leaders NEC AMD Intel nVIDIA are good - - - - Ali SiS VIA are not so good In the beginning all appeared to be fine but as the devices became more sophisticated then devices that were already installed began to fail after camera installation Design Criteria became important Power Regulation Inrush Current Oscillations Grounding/Ground Loops Working Temperature Wire Harness Chip Location Track Layout Track Capacitance Line drops
The Device Manufacturers have part ownership of the installation problems as well So it is a matter of matching specifications PC Motherboard Peripheral Devices PCI Cards OS User and keep in mind More $$$$$$ is not always the best - - - - Bigger is not always the best - - - -
Just more USB info to give you some Insight on Design & Specifications
Just keep in mind That your Posts are being viewed by many others so far only 49 The point is That we are helping more than just author of the topic/thread And perhaps this will initiate a New Member

Remember Geeks to Go
is here to help Good Luck
