I have a CM11 that I used on my PC. I bought a USB PDA/Serial Adapter to connect the unit to my USB. I get the message "Failed to open serial port with X10 interface. Make sure the correct interface type and port are chosen in the Preferences dialog and that the serial device or adapter are pluggted in correctly." I am assuming my computer is recongnizing the unit because I see it in the System Profiler under USB BUS as a USB-Serial Controller D. I am using Indigo v 1.8.0 (I've uploaded the software updates and not quite sure what to do with them) and I am using Mac OS X 10.4.8.
Any insight as to what I can do? I'd like to stop using my PC.
