: Modern Windows updates often automatically deploy a generic "USB Serial Port" driver that works seamlessly with Cisco hardware without manual installation.
On Windows 10/11, you may need to temporarily disable driver signature enforcement.
However, based on the naming pattern, this file likely relates to for Cisco ASR 900 series routers (possibly a typo: ASR-9xx instead of ASR-900). Here’s what you should know: Asr-9xx Usbconsole Drivers.zip
: A modern interface designed for direct connection to laptops without a serial port. On models like the ASR 920-24SZ-M , this may utilize a USB Type-A to Type-A cable. Why You Need the USB Console Driver
The file asr-9xx_usbconsole_drivers.zip contains the necessary software to enable a USB-to-serial connection for , specifically models like the ASR 902 and ASR 920 . These drivers are required for your PC to recognize the router's USB console port as a valid COM port for terminal access. Installation Steps To set up the console connection using this driver package:
Some engines (McAfee, Bitdefender) flag the .sys driver as “PUP” (Potentially Unwanted Program) because of its rare VID/PID. This is usually a false positive. Upload the driver to VirusTotal; if only 1-2 engines detect anything, it’s safe.
: It enables a direct terminal connection without needing a traditional RS-232 serial cable or a USB-to-Serial adapter. Commonly, the contents include: A Complete Guide to
: Drivers are typically found on the Cisco Software Download site under the "USB Console Software" category for your specific router model.
Complete Guide to Cisco ASR 900 Series USB Console Drivers Managing Cisco Advanced Services Routers (ASR 900 Series) requires a reliable console connection. Modern Cisco routers feature a USB Type-B mini console port alongside the traditional RJ-45 serial port.
While named after the ASR 900 series (such as the ASR 901, ASR 902, ASR 903, and ASR 920), this driver package is universally compatible with almost all Cisco routing and switching platforms that feature a USB console port, including Catalyst switches and ISR routers. Where to Safely Download "Asr-9xx Usbconsole Drivers.zip"
Wrong driver or corrupted USB stack. Fix: Uninstall the generic driver from Device Manager, delete the device, then disconnect/reconnect. Reinstall using the silabser.inf from the zip. Here’s what you should know: : A modern
You should always download these drivers directly from the official Cisco Software Central portal to ensure security and compatibility. Official Source: Cisco ASR 900 Series USB Console Driver Alternative:
A: Rare hardware defect on early ASR-903 units. Solution: Update the router’s FPGA image (requires XR maintenance window), then apply the firmware tool from the driver zip.
: It isn't always a "one-click" process; you may need to manually point Windows to the extracted folder in the Device Manager to complete the setup.
The is more than just a driver—it’s a lifeline for mission-critical legacy systems in aviation, marine, and industrial environments. While installing it on modern operating systems requires deliberate effort (disabling signature enforcement, manually pointing to INF files), the reward is continued access to specialized telemetry and control interfaces.
