// ABOUT SUBCLASS, only sub class 6 must be used for new design.
// What is the SCSI transparent command set (Sub Class 6) ?
// The SCSI specifications are available from http://www.t10.org/,
// but these documents don't mention a transparent command set.
// According to its creator, subclass 06h means that the host should determine the device type by issuing a SCSI INQUIRY command.
// In the returned INQUIRY data, bits 4..0 of byte 0 specify a peripheral device type (PDT).
// The SCSI Primary Commands (SPC) specification defines various PDTs and the specifications they should comply with. 
// The code in the VERSION returned in INQUIRY corresponds to a command set of PDT.
