John, I realize I'm coming into this late, but absolutely have never had a problem with FTDI USB cables - Prolific was always hit or miss.? For many years now have purchased FTDI cables from Mark KJ6ZWL (BlueMax49ers on eBay), have enjoyed excellent response time and not a single failure yet.??
Replaced our old IC-718 with a 7300 a couple years ago, but here is the FTDI USB CAT cable for the 718:
