The MCCI® USB 3.0 Connection Exerciser Model 2101 automatically connects and disconnects a USB2 or 3 host and device under push-button or software control. Connections can be single-stepped or repeated. The manual modes are useful for debugging attach/detach scenarios. QA teams find the automatic repeat modes useful for regression tests.
It's an ideal tool for finding and debugging connect/disconnect bugs in host drivers and devices.
