It has peripheral device type 3 which is for "processor". That will either be a SAFTE (i.e. SES like) device or a scanner (unlikely). If it is a SAFTE device then have a look at: http://oss.metaparadigm.com/safte-monitor Doug Gilbert - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
