USB Host Testing: USBHost Tester



An innovative solution allowing you to test your USB host !

Incompatibilities between an embedded USB host and the multiple devices with which it has to connect can alienate consumers and have serious commercial consequences.

Background
Consumers are accustomed to seamless USB connectivity between PCs, most of which are Windows-based, and standard peripherals and devices. They have the same expectation of the new generation of embedded hosts - mobile phones, automotive infotainment systems, TV set-top boxes and others - most of which do not use the Windows operating system.

However, USB devices that work well with Windows are not necessarily compatible with non-Windows embedded hosts. The connectivity problems that often ensue can lead to consumer dissatisfaction, support issues and even product recalls.

While many manufacturers currently perform a degree of testing on their embedded USB hosts, those tests are limited and most of them are performed manually.


The Jungo Solution
Jungo's USBHost Tester checks the stability and functionality of an embedded host stack and its compatibility with a wide variety of device types. The comprehensive test routine, which even includes extreme scenarios such as disconnects during transfer, gives you the confidence you need that your product functions as intended and will not fail the test of connectivity.

The USBHost Tester is invaluable for every industry that makes use of USB connectivity, including:

It is also used by USB Silicon Vendors to validate their reference designs and evaluation boards.

The USBHost Tester simulates the real-world behavior of a wide range of client types. It includes a comprehensive set of over 50 pre-defined transfer tests between the host and the client, assessing the performance, functionality and robustness of the USB host stack.

The USBHost Tester also automates the testing process, eliminating the need for manual intervention and drastically reducing the duration of the test cycle.

Among the tests that the tester runs are:

  • Negative testing – i.e. testing for known bugs
  • Stress Testing
  • Transfer testing
  • Parallel device testing

A Unique Productivity Tool
Jungo's USBHost Tester is the only product of its kind. Its ability to simulate USB devices operating in a real-world environment expands the range and validity of USB host testing substantially. It comes in an easy-to-use hardware and software package, comprising:
  • One or more device simulation cards
  • A control application
  • A transfer test driver
