Great. > I understand that getting the kernel messages via a USB console isn't > reliable. But I can't get the system/rc/initscripts startup stuff via > ttyUSB0 either. Or is this just as unreliable.. The only way I get > system/rc/initscripts startup stuff via ttyUSB0 is if I set > 'CONSOLE=/dev/ttyUSB0' on my kernel command line..

That CONSOLE= line is probably what init is reading to do what you need it to do. I don't know about the baud rate issue, sorry, try reading the documentation for your distro about this. thanks, greg k-h ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
