Hi,
It shows up at /dev/ttyUSB0. I have tried that command line several
times. Nothing happens. ps -e shows gpm is running. The pointer will
not move and the mouse buttons have no effect.

I have tried using minicom to connect to the mouse and that works in
that the minicom cursor moves toward the right with mouse movement.
So the hardware is functional. I know the baud rate is 1200.
Best regards,
Fred
