Control lego IR tower using NQC by usb port

[kuliar]

Hi all,
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.

You may need to compile your own kernel.

I know that there are options in the kernel config for Lego, and I doubt that the Fedora kernel would include them.

Is there anything in dmesg about the Lego tower?

I am not familiar with the dmesg command.
Could you suggest the way to use dmesg to clarify anything?
Thanks a lot.

I can see the tower been recognized as /dev/legousbtower0.
Does that mean my kernel already support it?
Compiling kernel will be the last thing I would try.
