I just looked to my /var/log/messages after enabling log in /etc/udev/udev.conf and i can't understand this : Apr 12 19:12:01 bureau kernel: ehci_hcd 0000:00:02.2: new USB bus registered, assigned bus number 1 Apr 12 21:11:15 bureau udev[1061]: creating device node '/dev/tty0' Apr 12 21:11:15 bureau udev[1061]: creating device node '/dev/tty1' Apr 12 19:12:01 bureau kernel: ehci_hcd 0000:00:02.2: USB 2.0 initialized, EHCI 1.00, driver 26 Oct 2004 Apr 12 21:11:15 bureau udev[1061]: creating device node '/dev/tty10' Apr 12 19:12:01 bureau kernel: hub 1-0:1.0: USB hub found Apr 12 21:11:15 bureau udev[1061]: creating device node '/dev/tty11' there is a lot of consecutive logs with very different time. udev and kernel don't use the same clock ?
