Tired of manually plugging/unplugging USB devices to test or debug driver load/unload problems? Are you wearing out the connectors on your development PC? Is your prototype so fragile that plugging and unplugging risks damaging the unit? Want to run connect/disconnect tests overnight?
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 or disconnect bugs in host drivers and devices. Simply connect your host and device to the connection exerciser, supply power, and you're ready to test. A single button push will connect or disconnect your device. Select "auto" mode to automatically repeat enumeration testing. Connect USB 3.0 Super Speed devices in high-speed mode to test backwards compatibility. Use a test control computer to automatically vary the test cycle time.
