[btw: now there is a /dev/da0 again, but no /dev/da1, last time I had no /dev/da0 but a /dev/da1, an so on; I've not yet found out under what condition a given /dev/da# is created at boot time. If I connect a usb memory stick then there appears automatically a /dev/da#s#, some examples: /dev/da1s1, /dev/da4s1, /dev/da0s1, /dev/da6s1 etc. The mounting of the memory stick to these dev-files is no problem; I've only problems with th usb mp3 player.] > These permissions will last until you remove the device.
