Yes. Each route processor has its own USB console port. You can connect to either RP independently, but you cannot share one USB cable across both.
| Issue | Solution | |-------|----------| | No COM port appears | Check USB cable, try another port, reboot router | | Drivers won't install | Disable driver signature enforcement (Windows 10/11: Advanced Startup → Disable driver signing) | | "Access denied" on COM port | Close other terminal apps, restart PC | | Garbled output | Check baud rate (9600), flow control = None | | Router not responding | Console cable might be plugged into wrong USB port (use , not USB storage) |
Complete Guide to Cisco ASR 9xx USB Console Drivers When configuring hardware from the (such as the ASR 903, ASR 907, or ASR 920), managing out-of-band connectivity through a terminal connection is crucial. Traditionally, network engineers relied on standard DB9-to-RJ45 rollover cables. Modern laptops rarely feature integrated serial ports, forcing a shift toward native USB console interfaces built right into the Route Switch Processor (RSP).
