Loopback log missing is strange indeed: lo is configured anyway, but it doesn't log when usb is not working. > > I really don't know what the first two entries mean, nor what they could be related to. > > Any help? These are the only differences i could find, plus one more in ntpd log: when usb is not working, ntpd gets initialized with a frequency of 24.170 PPM from /var/lib/ntp/drift - when usb is working, the frequency scales down to 16.787 PPM.
