Multiport USB hubs/switches on Raspberry Pi

[bob prohaska]

Does anyone have experience using multiport USB hubs on freebsd-arm,
specifically in the context of Raspberry Pi 2 or 3?

I'm interested in trying to use a hub/switch (not sure there's a
difference in the case of USB) to construct a terminal server for
serial console access on a small cluster of Pi's. I'd want about
seven or eight ports, each holding a USB-serial adapter that would
then connect to the GPIO UART pins on one Pi in the cluster. I've
used both USB 3.0 and USB 1.1 hubs, and in both cases odd things 
seem to happen from time to time. One potential example is

If anyone has experience along these lines or a suggestion for/against
particular USB devices or versions I'd be curious to know.

Thanks for reading,
