Hello and welcome to ABAdss
Thanks for taking time to introduce your self.
I have seen a USB port on some of these units but from my understanding the only way to upgrade the sofware(BIN) is thru a serial cable.
Sv1000pvr updates with usb from back of receiver you don't need to update with cable mine works great.
Testing sv8000hd,sv4000,sv1000pvr,neosat ipro2k,nfusion nova,viewsat ultra.
