12.5 Exerciser Files
The system generates USB 3.0 traffic from traffic generation files (*.usb3g) which are
text‐based script files that instruct the Exerciser how to generate USB 3.0 traffic. These
script files can be edited with either a simple text editor such as Notepad or with the
Script Editor utility provided by the application.
12.6 Creating Exerciser Files
If you choose to write a script with a text editor, a good way to start is to edit a sample
generation file.
For Windows 7 and Windows 8, an example such as: MassStorageEnumeration.USB3g,
SampleEnumHostTx.usb3g, or SampleMassStorageHostTx.usb3g, in the directory
C:\Users\Public\Documents\LeCroy\USB Protocol Suite\Examples\3.0 Host
Emulation\LowLevelScripts.
For Windows XP, an example such as: MassStorageEnumeration.USB3g,
SampleEnumHostTx.usb3g, or SampleMassStorageHostTx.usb3g, in the directory
C:\Program Files\LeCroy\USB Protocol Suite\Examples\3.0 Host
Emulation\LowLevelScript

You can open a generation file with Notepad or other editor and then add or remove text
as needed.
