USB Loopback Plugs

USB 2.0 Loopback plugs can be used to help diagnose, troubleshoot and load test your PC’s USB 1.x and 2.0 ports. Five status LEDs on the USB 2.0 Loopback plug will dramatically improve the troubleshooting and diagnostic ability of computer technicians and system integrators, who have previously been working blind.

The Red, Green and Yellow LED's on the front of this USB adapter plug provide a quick visual indication of I/O activity and if the USB bus is powered. The Orange LED will provide a quick indication whether the PC port is currently supporting the higher USB 2.0 speed (up to 480Mb/s) or the lower speed found with USB 1.x (of up to 12 Mb/s). The leftmost red LED indicates whether recoverable bus error (retransmission of data) has occurred.

These plugs are unique! They are the only true USB 2.0 loop back adapters on the market and have been especially designed for use with our BurnInTest Professional software package. They do not require an external power supply and do not require a connection to any other port on a PC. Each plug also has its own serial number stored in EPROM, on the plug, so it is possible to identify each plug when multiple plugs are connected.

Each plug also contains its own CPU and executes its own firmware (which can be upgraded in the future by download)
