Ugh! Sorry to hear about that. It looks like it could be a standard component that you might be able to get from a local electronics store or order from digikey. Unfortunately, it would have been easier to tell what it is before it got burnt, but if you can tell, that would be the cheapest thing to try first. If you can't, maybe there are some other pictures of disassembled devices, or maybe someone else who had to fix their USB cable can tell you what it was. As you can easily see, there isn't much traffic on this forum anymore, but hopefully you'll get some kind of help with a bit of patience.
