A simple test? Try "echo", but don't rely on the data it sends, or any line settings :) I have a loopback script that I use to test the driver around here somewhere if you're interested in it. Why not try a 2.4.19 kernel? thanks, greg k-h ------------------------------------------------------- This sf.net email is sponsored by: To learn the basics of securing your web site with SSL, click here to get a FREE TRIAL of a Thawte Server Certificate: http://www.gothawte.com/rd522.html _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users
