PassMark Software


Tooling & Production

USB 2.0 Loopback plugs are one of the fastest methods to diagnose, troubleshoot and load test your PC’s USB functions.

When used with compatible PassMark testing software (see below) is it possible to:

  • Quickly check if a USB port is powered;
  • Check that data can be sent and received from the port;
  • Check USB errors rates and transmission speed (up to 480Mbits/sec) in Windows;
  • Measure the level of recovered data (retransmitted frames);
  • Verify that the system remains stable under long periods of load;
  • Test that USB support in Windows or Linux is available;
  • Test self powered USB hubs and PC ports function correctly;
  • Check USB cabling;
  • Concurrently check multiple USB ports at the same time;
  • Benchmark your PC’s USB ports & hubs; and
  • Check if your PC ports are high speed 480Mbits/sec (USB 2.0), or full speed 12Mbits/sec (USB 1.x) via a LED
