Control lego IR tower using NQC by usb port
I would like to build a robot using lego mindstorms kit.
I have a RCX 2.0 box, and I want to use NQC to do some programming.
The IR tower can be detected in my fedora 5 linux desktop as /dev/legousbtower0.
But when I typed "nqc -S/dev/legousbtower0 -run"
There comes error message : "Could not open serial port or USB device."
But I can see there are green light shining for a while inside the IR tower when I typed the command.
How can I make this USB IR tower work?
Let me know what you think. :D
