SourceUSB Log View

SourceUSB captures USB requests and displays them real-time in the Log View. In this example, the records were captured during operation of a USB flash drive. It shows bulk transfers, both input and output. Each transfer is represented by 3 rows in the window. The initiating request has an URB Type with a dark blue color. When the dispatch routine returns, an URB* Type record is added in light blue (these have a STATUS_PENDING Irp status). When a transfer completes, another URB Type record is added, also in light blue (these have a STATUS_SUCCESS Irp status).

On the left hand margin of the window, notice the tabs labeled: "USB Device Tree", "Stack Inspector", and "Device Properties". When these windows are "un-pinned", they are hidden from view. Hovering the mouse cursor over these tabs will temporarily show the corresponding window until the mouse focus is removed. Hiding these windows helps maximize the usable workspace area.
