SourceUSB 3.41

SourceUSB is a software-only USB analysis tool. It is installed on a Windows operating system as a kernel-mode driver and user-mode application. The analyzer driver coexists with the Windows USB driver stack.
Since USB is a host driven bus, viewing USB activity from the host perspective is a valuable complement to viewing USB transactions on the bus with a hardware analyzer.
SourceUSB installs easily from a Windows Installer package. Separate packages are supplied for 32-bit and x64 platforms. It does not require any changes to existing drivers to benefit from its use.
SouceUSB records USB I/O requests and events in a binary log file and displays them in real-time. Requests and events can be logged from the time the system boots or logging can be easily started and stopped using keyboard shortcuts or menu commands.
Filters can be applied to control the amount and type of information which is captured or displayed. All transactions are time-stamped to aid in performance analysis.
SourceUSB allows you to examine each I/O request or event in detail. For example, the fields in setup packets, URBs, and descriptors are displayed and annotated. The request, response, and pending phases of each I/O request are displayed separately with the completion status.
