On some Cisco routers there is the plain serial management port on a USB-A connector. (Do not confuse with the USB-A connectors that provide a serial console but are a normal USB connection that require a USB rollover cable!)

Probably the whole Cisco ASR 920 Series is affected but to name some devices:

• ASR-920-12CZ-D
• ASR-920-12SZ-IM

Cisco is selling adapter cables to their normal RJ-45 console port pinout as A920-CONS-KIT-S=.
