different laptops.  It was written by ENE, but cleaned up to
work properly in the kernel tree by Novell.

+	  Say Y here if you wish to control a ENE Card reader.
+
+	  This option depends on 'SCSI' support being enabled, but you
+	  probably also need 'SCSI device support: SCSI disk support'
+	  (BLK_DEV_SD) for most USB storage devices.
+
+	  To compile this driver as a module, choose M here: the
