There is an ability to hide/unhide specific (user-defined) types of URB packets.
It's useful if you want to see only those URB packets which are needed for analysis.
To setup showing filters click 
on toolbar. In appeared window, select only those types of packets that you want to see.
Then click OK.
You can also filter events by pipe and interface. Right-click in the Events window and select the required filtering type.
