Yes, it should all "just work". Just point your program to /dev/ttyUSB0. > If all of this is true then it's curious that this just doesn't work. > Perhaps I've found a problem.

Some usb-serial drivers do not handle all of the different serial ioctls (don't know about this driver, as I didn't write it.) For example, the "setserial" program will not work on most usb-serial drivers (the io_edgeport and io_ti drivers being the exception). thanks, greg k-h ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users
