a.EVPD (enable vital product data) : Byte 1

This scanner does not support EVPD. If this bit is set to 1, the scanner returns the following error information:

f Status: B©00001￿ (CHECK CONDITION)

f Sense key: X©5￿ (ILLEGAL REQUEST)

b.Page code: Byte 2

This scanner does not support page code. If this bit is set to 1, the scanner returns the following error information:

f Status: B©00001￿ (CHECK CONDITION)

f Sense key: X©5￿ (ILLEGAL REQUEST)

c.Allocation length: Byte 4

This field specifies the storage area in bytes that the initiator allocates for inquiry data. If a 0 is set here, inquiry data is not transferred, but this is not regarded as an error. The target terminates the DATA IN phase when it has transferred either the bytes of inquiry data specified in this field or all of effective inquiry data.
