[/home/harm]$umount /mnt/usbreader umount: /mnt/usbreader: device is busy $fuser /mnt/usbreader shows its not in use at all. Mounting and writing/reading does work. weird thing: This only happens when the PC boots with the card reader connected. If I actually unplug the device and plug it back in, then mounting/unmounting does work. Anyone an idea ?
