The L210, NX210, SX210 and TX210 series are supported, yes.

Hmm, the epkowa backend is an external SANE backend.  It is *not* part
of the libsane package you installed.  I assume you installed the iscan
bundle available from:

  http://support.epson.net/linux/en/iscan_c.php?version=1.0.4

OK, so you've got an L210 Series device.

OK, so you've got iscan installed ;-)

Looks like you have a permissions problem.  Your user needs to be part
of the scanner group.  Is it?  You can check with

  $ groups | grep scanner

If this produced no output, you can fix that with

  $ sudo adduser swami scanner

Then log out of you desktop session and back in again.  If it was indeed
a permissions problem, you should now be able to use your scanner.

Hope this helps,
