Until you try the IR tower on another computer (that is not identical to yours), you have no way of knowing if the tower is the problem is in the USB device or in the USB chipset. At this point, I'd cut my losses (and time) short and spend $25 on a (...) (22 years ago, 25-Nov-03, to lugnet.robotics)

Ruth, If the tower works on another computer, then at least one of the following will be true: 1) There is some sort of hardware conflict that is aggravated by accessing the IR tower 2) There is a software conflict 3) The computer has a combination (...)

Just some general ideas. If you're not using the firmdl or lejosfirmdl that came with lejos, try using one of those. Some versions of some downloaders have trouble with the lejos firmware. If you haven't tried fresh batteries in your RCX, try that. (...) (22 years ago, 25-Nov-03, to lugnet.robotics.rcx.java)
