Are we looking at a front port of back port? If its a front port, the design is prprietary so there is not real easy way to replace it short of finding the same model and taking it from that.
if its a back port it would require a really good soldering job and in most cases since they have started to use wave soldering, near impossible to do without damaging the mobo.
If it is a front port though you could check the solder joints and wires. Most of them have exposed joints and thats a bit easier to fix.
Or do it the easy way and get a PCI USB card.
