Soldering a TRS to TRS cable?

I am trying to make a transfer cable for my TI-84 Plus Silver Edition Calculator. It came with a USB-mini to USB-mini cable, but it has two ports on top. One for a USB-mini cable, and one for an I/O cable, with 3/32 TRS jacks (2.5mm) from Radio Shack. I am wondering how to connect two TRS jacks together to make a transfer cable. I don't know what kind of wire to use, or how the wires should be connected.

USB is a high speed digital format signal with 5V power,
while a 3/32 jack is a stereo analog signal format and the
only place they meet is in a DSP (  Digital Signal Processor  )...

Probably just solder the same contacts to eachother with wires
