Overview of ASR9xx USB Console Drivers

Version Matching: The driver version must match your Route Processor hardware revision. An RSP5 requires a different PID than an RSP880. The asr9xx in the name is generic; check the included .inf file for specific hardware IDs.
Never use Windows Update: Microsoft may push a generic "USB Serial Device" driver that overrides the Cisco driver, breaking break detection. Use Group Policy to prevent automatic driver updates for the specific VID (e.g., 0403 for FTDI).
Keep a local copy: Store asr9xxusbconsoledriverszip upd on a USB recovery stick inside your toolbox. When a router blacks out during a maintenance window, you won't have time to download drivers.
