I can’t remember if the Pronto is USB, but the Pront NG is and is fairly quick… maybe 30 secs to a minute to update. I got mine in the states and it wasn’t quite as offensive as the UK Pronto price was. Zee even through the NG off a wall (forcefully with rage) and it still works, whereas the Pronto fell on the floor once, and was never the same again hehe.
