1) Poseidon itself does not like cheap hubs and gives error messages or errors
2) I had to pay 30 US Salad leaves to get a hub it did not give warnings about
3) If you have a printer with a Centronics interface, it always works better going parallel-to-Centronics. I got so fed up I bought a "LPT2USB" device to handle those issues until I was able to put both my printers on my home network.
