Yeah, usb-serial as a boot console is a joke (code was written on a dare), and due to buffer sizes, and the lateness of the USB code getting initialized, doesn't really work very well. There's really nothing you can do about it, but it seems to work for some people, and they like it, so we aren't going to remove it :) > Oh, and ttyUSB0 doesn't end up functioning as a console > whatsoever once init starts up.. That should work properly, do you have your inittab set up correct for that? That is required. thanks, greg k-h ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
