which pin is missing?
Alright.. i was going to put my auxiliary usb module onto my epia board when i realized.. wow this things is missing a pin. After consulting my handy little user's manual i find that it needs some sort of proprietary type module.. argh.
Also It has something for video input .. not sure how you'd make use of that though..
Anybody have any ideas or know where to get this piece?
which pin is missing?
normal usb header looks something like this
this one looks like this
and the book says it uses nonstandard something or other
dont take this a gospel, but sometimes the missing pin is used as a 'one way only' system..... I have even seen serial/parallel port pins on old AT mobo's with the same system....
try getting a usb header cable/socket and pierce a small hole thru the missing bit ( love my explination!) using a small nail/pliers etc, so that the cable socket can accomodate the extra pin.... you might find that it will work..... this is what I needed to do with serial/parallel port cable sockets on mobo's of this type....
hope that helps..
Project - GAME OVER :(
well that's not the problem.. the problem is that the standard connector is meant to connect to a 9 pin header.. this header only has 8
looking at the connector .. there is only 8 useful ones.. but i don't want to screw this up and fry the board
You're just going to have to get the pinouts for both and get creative
i have one of these and noticed that an i wasnt pleased either
maybe you should try meialing via. they might be able to help?
I think the extra pin is just an extra ground.
I had never used the headers on the mobo for USB before I started my project.
I used a multimeter and found the extra pin to be a ground, The sockets that plug onto the headers have got 5 wires in them but the last 2 are both grounds.
Hope this makes sense.
Possible reason for the extra pin on one of the sockets - I think it is used if you use a powered USB hub, as there would be more power returning to the mobo than it sends down the positive, because it is added to by the hub. (don't quote me on that though, cos really I have got no idea)
You should be able to use your normal USB header socket, and it will overhand the header pins, but the wire that is not connected is just an 'extra' ground.
It all looks a bit complicated to me
1st attempt went OK, but was too slow. Next version is all onboard, will use push buttons on the com ports, got a 200MHz 6x86, 128MB RAM, Winamp. Sproggy 2.6 kit in progress. 12GB Laptop HDD. No case yet!
That's not necessarily true.. it may not be as simple as a missing pin.. They may be arranged in a different fashion.
Also the extra pin doesn't connect to anything.. it's like magnitek called it a "one way only" pin
The header (for usb as well as any thing else on this board) are mini-sized. A standard usb expansion card (with the 9 hole connector will not fit the pins anyway. A special sized plug is needed. The cdrom requires an older mini plug as well.
