About USB Decoder Parameters

The USB Template function provides the capacity to create multiple templates that contain different parameters. This capability allows the user to maintain individual templates for each USB network monitored. Applying a template containing only those parameters necessary to decode transmissions particular to an individual network, enhances the efficiency of the analyzer to decode data.

Each entry in the Set Initial Decoder Parameters dialog takes effect from the beginning of the capture onward or until redefined in the Set Subsequent Decoder Parameters dialog.  

The USB Set Initial Decoder Parameters dialog requires the following user inputs to complete a parameter:

• Function Address (Range: 1-127) - This is the decimal address of the USB port that connects the device to the computer.
• End Point Address (Range: 1-15) - This is the decimal address of the operation within the device.
• USB Carrying - Select from the list to apply the Universal Unique Identifier (UUID) of the application layer that USB traverses to from the following:
