TP-Link SG3428: reconstructing its USB console access

TP-Link SG3428 USB Reset reconstructs access to a JetStream switch's USB console through a Python raw-USB client. The investigation found that a vendor-class interface responds to CDC ACM line-coding requests; the tool sets 38400/8N1, exchanges data over bulk endpoints and exposes an interactive console, baud scan and BootUtil reset workflow.
