USB console cable for Cisco Catalyst

Cisco’s new line of equipment now use a mini-USB cable for console configuration. There is no longer a need for a USB to serial adapter or a roll-over cable.

Connecting the USB cable on Linux should give you a new ACM device that looks something like this: “/dev/ttyACM0″.

To verify, you can also look through your dmesg or /var/log/messages :

[265430.720082] usb 4-1: new full speed USB device using uhci_hcd and address 4
[265430.914246] cdc_acm 4-1:1.0: This device cannot do calls on its own. It is not a modem.
[265430.914305] cdc_acm 4-1:1.0: ttyACM0: USB ACM device
