This could be useful for beginners. When a SCSI device is found, we
could stat() it and give a warning if it is accessible only to root.
Even more, if it is accessible to some group, we may print this group
name.

We could do the same thing for USB devices (at least when using the
kernel scanner driver - libusb will be more tricky).
