In the old days with FSX/P3D, USB 2.0 was my preferred choice (see Post 582) when connecting Saitek/Logitech Flight Instrument Panels (FIPs) to the simulators.
Since I replaced my older computer for MSFS in last November, I’ve been deliberately avoiding to use any more USB 2.0 ports and hubs. Now all my 12 FIPs are connected to the system via a powered USB 3.0 hub.
In the past 6 months, I didn’t see any issue caused by the newer USB version as it did to my older computer in the past.
I am not sure if it is the new hardware or the new MSFS that breaks the barrier.
But whichever it’s true, it is definitely a good thing that we are no longer bounded by the old USB 2.0 standard any more, isn’t it ?
Your mileage may vary.
