I tried plugging the Fez Lynx card to a USB 3.0 and does not work correctly, USB 2.0 works fine. is there any driver for USB 3.0?. I am also working with Fez Lynx, "Hub AP5" and 2 cards "RelayISOx16" and noted that the activation of individual relays is very slow when I plug the card Relays to Sockets Hub, however when connected directly to the Fez works fast (but I need 2 sockets Y). Is there any way to reduce the time between activation of relays using the Hub card?. I modified the file RelayISOx16.cpp, removing almost all "system :: sleep (100);" (although I guess it's not recommended) but neither works.
