Windows 7: Internal 9 pin usb header to male usb 2 plug?

Hi there,

I am very good at posting threads in the wrong place so, if this thread is in the wrong place, I apologise in advance.

Anyway, I have a mem card reader with a 9 pin internal usb header. I need to convert it to a normal male usb 2 plug but am just wondering what wires would lead to where! Here are some other images that could help! I can see that this may not be possible, I hope it isn't too much of a noob idea but I am sure someone here can help ! Anyway, here are the additional pics if they help at all!

Any help would be much appreciated!

So instead of of connecting into the prongs, you want to connect the prongs into something? is that about right?

Firstly, thank you for replying, much appreciated. No, basically I have a men card reader and it has a 9 pin internal header, the USB ones. I am unable to plug it in internally for various reasons. Therefore, I am going to have to connect it using a normal USB 2 plug, like the ones you see on mice and keyboards. The problem is that the male plug has 4 connections, the internal one has 9. However, the connections are very similar ad you can see from the pics i gave. I need to remove the internal header and replace it with a normal plug. Problem is I don't know where the wires would go. Would using two USB male plugs work?

I hope this makes it clear, sorry for being confusing! Thank you very much for replying.

Hi Music Guy
For what you are asking, the answer is technically yes. There is a workout to manipulate it, but a lot of thing to make sure first.

• How many pin are wired from your card reader? Mostly only four needed from two rows (the original pict might do). Unless your card reader use all 8 pins (one is blank)
• Are you familiar working with a multitester and soldering?
• Do you have any USB plug (mostly unavailable at PC store). Have to cut any unused USB extension cable.

If you are compeletely sure, I can provide you assistance. But bear in mind, any mistake on putting the cable on the wrong direction is definitely a disaster though it's only 4 pins, first to the card reader, and the main board USB regulator follows.

Actually Vierasniper have the point. If you manage to open the case and find any free USB header. You are out of any possible trouble.

Kevin is right, it can be done but its time consuming and you cant mess it up. so i looked up your motherboard, and this is on a laptop?

Yes, I don't think I explained the situation very well, sorry! My friend has an old mem card reader that has a 9 pin usb header. I want to be able to connect it to my laptop, our home desktop and other laptops. I will find out how many pins are actually connected to wires for you guys. I am very familiar with soldering and can test stuff although I don't have a multitester. I do have a usb plug, well, several of them. Thank you both for your help so far, plus reppies are on the way!

The motherboard header is actually two USB ports. You'll have to look at the cable on the card reader to see if it uses two ports.

This is the pinout for my motherboards USB header.

1 2 3 4 5
o o o o o
o o o o
6 7 8 9

1 = +5V
2 = Data -
3 = Data +
4 = Ground
5 = No Connection (used as a keyway)

6 = +5V
7 = Data -
8 = Data +
9 + Ground

As far as the cable goes: USB pinout and wiring @ pinouts.ru

This is it right here, this is legit.

I found this so far...

@alphanumeric, thank you very much. That is incredibly helpful. So I guess that I just use to male USB plugs then?

@bassfisher6522, thank you, the only problem is that only has a 4 pin header.

Overall, I guess I have to use two USB plugs then. Is that right? Thank you very much for all the help so far, it is much appreciated!
