The event is ~2—3 hours or so. If someone needs the full Debian (80 gb!), I think USB 2 would not work in that timeframe. USB 2 sticks may be rare, but at this event there are ppl with old laptops that have no USB 3 sockets. A lot of people plug into ethernet. And the switch looks somewhat more serious than a 4-port SOHO… it has like 20+ ports with fans, so I don’t get the impression ethernet congestion would be an issue.
