You should not rely on USB bus numbers or USB device numbers for anything. Use the serial number of devices in order to access them in a persistant manner. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
