What problem does it solve? Configuring and driving an MCCI Model 3411 "Merganser" USB 3.2 Gen2 test device is error-prone: its control port enumerates as a generic FTDI FT2232H (0403:6010) rather than the documented MCCI VID/PID, only one of the two serial channels answers, and the RTEMS shell's pager silently eats keystrokes. This Skill handles all of that so you can switch device personalities and run throughput tests reliably. ## Core Features & Use Cases - Control-port automation: Auto-detects the correct FT2232H channel-B serial node, handles the pager, and runs RTEMS shell commands (mode, speed, buffer size, VID/PID override) via the bundled mcci3411.py helper. - Personality switching: Sets compliance, loopback, or multi-bulk device modes and forces enumeration speed (FS/HS/SS Gen1/Gen2) for host-controller and hub testing. - Throughput and integrity testing: Guides host-side usbiotest runs with correct pipe notation, buffer sizing, and benchmark/integrity test types. - Use Case: Benchmark a new USB 3.2 Gen2 host controller by putting the 3411 in loopback mode, then running a 100-iteration bulk benchmark from the system under test and verifying it approaches line rate. ## Quick Start Ask the agent to run the mcci3411 helper's info command to detect the connected Model 3411 control port and report its firmware, mode, speed, and buffer configuration.
