Hi everyone, On my current robotics project, I'm using a gumstix verdex to talk over a USB to serial converter chip (FT232) to a serial bus. My brother Dave made up a new kernel driver for the gumstix, and when I plug in the chip it registers itself as ttyUSB0. For work I've done previously on Squeak on the gumstix, I've used standard serial ports, which map to ttyS0, ttyS1, ttyS2, etc, which correspond to port 0, 1, and 2 when I open the Serial Port in Squeak. However, I have no idea which port number ttyUSB0 corresponds to... Anyone got any idea?
I have to scratch this itch :-). This is something I should know but don't.
At a guess, I'd say this is your answer, from usb-serial.c in the Linux kernel:
..actually sorry; I misread your email.
