I need to install a card reader that also has a USB port in a desktop. There are no available USB motherboard headers for me to connect it to. I would like to cut the header off and solder on a regular USB type A plug in place of the header. The problem is that the USB cable has only 4 regular wires plus a bare ground, and the header has 9 wires. Can I double up some of the compatible wires or do I need to use two USB type A plugs. And if so with either option how do the wires go? On the header wire it has a red, orange, yellow, white, green, blue, brown, black, purple wires. The USB type A plug and cable I'm using has a green, red, white, black and a bare ground wire which I need to solder onto the internal card reader in place of the 9 wire motherboard header. So can and how do I make this work? I'm planning to run the cable through the case and plug it in to a port on the back of the tower. I have in the past, soldered USB wires for extension purposes before and they always worked well so the plan should work if I can hook up the wires in their correct place. Also I don't need for the USB port on the card reader to work at the same time that it is reading an SD card. As long as they will each work one at a time. The front USB port on the card reader would be used pretty regularly but the SD card reader would only be used occasionally.
