These are "pseudo" sources which can be used to read pnm-files. Choose
one, enter a existant filename (containing a pnm of course :-), and you
will see.
If you cannot access your scanner in this list, it is not configured
correctly or has lacking permissions.
Check /usr/local/etc/sane.d/dll.conf, if it contains the necessary drivers
e.g. net pnm and mustek for me and the mustek.conf (or equivalent, depending
on your scanner), if it has the right device entry.
Moreover I doubt, that your scanner is on /dev/sda4. sda4 is a harddisk
partition, and if a scanner really really says it is a HD partition (which
none of the supported scanners does AFAIK), the HW developer should be forced
to eat it.
Scanners are accessed via /dev/sg? devices which requires SCSI-generic support
in the kernel and devices are counted for getting the ?.
I.e. if the scanner is the first entry in /proc/scsi/scsi this is sga,
2nd is sgb, ...
