Actually wait a moment... In your code, did you issue CA_RESET then 
immediately try to read/write data? If so, that's not going to work; 
resetting the CAM can take up to 5 seconds, and CA_RESET doesn't wait.. Iin 
my userspace code I had to add a loop checking CA_GET_SLOT_INFO until it 
returned CA_CI_MODULE_READY.
