The Cisco USB Console Driver is a piece of software that allows your computer to communicate with Cisco networking devices (routers, switches, firewalls) using a USB console cable (e.g., CAB-CONSOLE-USB). Unlike older serial (DB-9) cables, modern Cisco devices use a USB Type-B mini port for console access. Without the correct driver, your PC will not recognize the cable, and terminal programs like PuTTY or SecureCRT will show no available COM ports. ciscousbconsoledriver31zip upd
