Decoding of Protocol-Specific Fields in
Transactions/Transfers
When transfers or transactions are displayed, the fields in setup transactions or
control, interrupt, and Bulk transfers by default do not get decoded and are shown
in hexidecimal values. The exceptions are setup transactions and control transfers
for standard USB device requests which are always decoded.
In order 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 will see the protocol-specific fields of transfers and transactions decoded in
the trace view.
