If you experience issues or want to ensure you have the latest version, you can update the driver manually.
Windows Device Manager will show an "Unknown Device" or "USB UART" under other devices.
Always source your infrastructure utilities directly from the official Cisco Software Central portal:
The ASR9xx series refers to a line of network processors and switch chips developed by Broadcom, used in various networking equipment. The USB console drivers are essential for establishing a console connection to these devices via a USB interface. This connection allows network administrators and engineers to perform initial setup, debugging, and recovery operations on network devices. asr9xxusbconsoledriverszip upd
Before updating, it's a good idea to check your current driver version. This can typically be done through your device's management interface or by checking the device's documentation.
The Mini-USB or Type-A physical port converts internal UART signals to a USB interface. Your operating system cannot communicate with this setup natively without a Virtual COM Port (VCP) driver. The package installs this VCP layer, mapping the physical hardware port to a logical COM address on your administration PC. Key Driver Updates and Compatibility
Officially, the underlying driver code for Cisco's USB consoles is built around standard USB-to-UART bridge chips (such as Silicon Labs or Exar/MaxLinear chipsets, varying by the specific ASR supervisor model hardware version). To get the cleanest, most up-to-date, and verified version: If you experience issues or want to ensure
Cisco ASR 900 series routers feature dual console port options to accommodate various deployment scenarios:
), you must download the official Cisco Virtual COM port driver. This driver allows your PC to recognize the router's Mini-USB or USB-A console port as a standard Serial COM port for terminal access via tools like PuTTY.

When working with carrier-class routing hardware like the (including the widely deployed ASR 920, ASR 901, and ASR 903 Aggregation Services Routers), managing local access is a fundamental task for network engineers. While older Cisco hardware relied heavily on the classic RJ-45-to-DB9 rollover serial cables, modern ASR 9xx platforms feature a built-in USB Type-A or Mini-B console port designed for direct laptop connectivity.
