USB device test suite

Ellisys has announced the USB Device Examiner, an add-on software package for its Explorer range of protocol tools.

The software verifies that a USB device under test complies with Chapter 9 of the USB 2.0 specification and, where applicable, the hub, HID and mass storage standard classes.

Used with a USB Explorer 260, the software automatically discovers the USB device under test connected to the generator and displays information about it.

The device’s class is detected and tests pertinent to that class are automatically loaded. The package then carries out a suite of tests, monitors the resulting interactions and generates a report detailing the pass/fail results of each individual test.

The software can also control a 260 protocol analyser unit to record a trace of every executed test, in case debugging may be required. If there are errors, the detected issues can be debugged using the analyser to examine the traces captured during testing.
