5.34 Decoding Protocol-Specific Fields in
Transactions and Transfers
When transfers or transactions are displayed, the fields in setup transactions and in
control, interrupt, and Bulk transfers do not get decoded (by default) and are shown in
hexadecimal values. The exceptions are setup transactions and control transfers for
standard USB device requests, which are always decoded.
To show specific decoding for class- and vendor-specific device requests and endpoints,
you have to use the decoding association mechanism that is described in Chapter 9 on
decoding. When you have performed the association, you see the protocol-specific fields
of transfers and transactions decoded in the trace view.
