Hello
First of all, it is not a USB port/slot, it is a 3.5 mm slot. And it can only be used Samsung technicians for "service" and nothing else.
Thanks for using Fixya!
Guru!
The model has both USB port and 3.5 mm Jack!

in order to upgrade the software you must give it to Samsung service as they don't upload the firmware on website.
in addition, you need to have their service software to do so which i believe is nearly impossible to get.
hope this was helpful
