(...) This sounds identical to the situation described by Rob Hendrix in (URL) Anderson from LEGO suggested via email that the USB port may not be giving the tower sufficient current. Perhaps you could try a powered hub? John Hansen (21 years ago, 19-Nov-03, to lugnet.robotics.rcx.robolab)

Hi, Nathan, I truly suspect that the issue is the Toshiba hardware of this particular laptop model. I have 3 Dell desktops, 3 laptops. They all have built in usb ports, either 2.0 or 1.0. They all work fine, with the identical setup up, even with (...) (21 years ago, 19-Nov-03, to lugnet.robotics.rcx.robolab)
