I commented out loadusr -W arduino /dev/ttyS0 3 from my HAL file and everything seems to be ok. I don't understand why the arduino and the hostmot2 would cause problems with each other though. One is a serial port and the other is a parallel port. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
