We met some friends for a cruise, and specifically set aside some time to scan something they brought along. But when I connected the POP 4 scanner to my MacBook it never showed as connected. The LED on the scanner went from red to green, but the software never said it was connected. After a half-hour of frustration and trying things, we gave up.
When I got home, I connected it, and it connected and had a firmware update, which I installed. Everything worked.
Why didn’t it work on the cruise? Does the software or scanner require an internet connection to work? If so, this should be made clear, to avoid massive frustration.
