This command requests that the device server send device identification
information to the application client.
The "Service Action" field can be specified only X'05'.
The "Allocation Length" field indicates how much space has been reserved for the
returned parameter data. If the length is not sufficient to contain all the parameter
data, the first portion of the data shall be returned. This shall not be considered an
error. The actual length of the parameter data is available in the "Identifier
Length" field in the parameter data. If the remainder of the parameter data is
required, the application client should send a new REPORT DEVICE
IDENTIFIER command with an "Allocation Length" field large enough to contain
all the data.
The REPORT DEVICE IDENTIFIER parameter list is shown in Table 4.34.
