RCX 1.0 = Infrared via serial (launched 1998)
RCX 2.0 = Infrared via USB tower (2001)
NXT = Bluetooth (2006)
WeDO = USB (2009)

The "legousbtower" module is needed for the RCX 2.0 Infrared Tower.

Including a udev rule might be a good idea though. Currently it is provided by the "nqc" rpm.

OTOH, there is no Sugar activity that uses the RCX, AFAIK. Worse, I don't even know any graphical Linux application to talk to the RCX. Do you?
