Some clarification on what the difference is between cuaU0 and > ttyU0 would be appreciated too and which of them I should use primarily. Adding some more info myself here. Initially I only copied the shared libraries the program needed from my Linux computer and loaded the linux kernel module. Installing the full linux_base-f10 port seems to get rid of the error message so it seems unrelated to the actual communication problem I experience. The program initially detects the card in the reader but as soon as I try to communicate with it, the program thinks the reader is empty. Does anyone recognize this behaviour? /Morgan
