Somewhere on the Mindstorms site, I found a reference to the Peracom adapter. I have not tried it, but I did buy a Belkin USB Hub with a serial port and I know that the Belkin doesn't work. Scott (26 years ago, 31-Dec-99, to lugnet.robotics.rcx)

I have a USB Hub with an RS-232 port. When I connect the IR Transmitter to this port, the firmware downloads fine. If I have a program with a single RCX command block, it's fine too. If I have more than one command block, I get a download error. Any (...) (26 years ago, 30-Dec-99, to lugnet.robotics.rcx)
