A logical object on a device has a unique 32-bit identifier (object handle). The object handle is also unique for the session (defined below). An object transfer contains all transactions for an object handle. In PTP, all object-handle PTP Transactions are a single PTP Object Transfer.
A PTP Object Transfer can include both PTP Transactions that involve an Initiator-initiated action (for example, GetObject, DeleteObject, and GetObjectInfo transactions) and
PTP Transactions that involve a single Asynchronous Event sent through the interrupt pipe. The PTP Object Transfer trace viewing level is the middle PTP level.
To view PTP Object Transfers, do one of the following to switch to the PTP Object Transfer trace viewing level:
-
On the toolbar, click the down arrow on
OR
-
From the menu bar, select View Level Viewing PTP Object Level.
OR

From the menu bar, select Setup > Display Options. Select the box for PTP Object and click OK.
