Using Cisco Mini USB Console Cable to Configure Cisco Switches and Routers

Cisco Device Mini USB Port
Cisco has added mini usb port into their products for many years.

The key to use this port is to get a right cable. At most situations we are using regular RJ45 console port with a USB to Serial Adapter connecting to your computers. Occasionally, you may need to have another console access for your multiple person's troubleshooting console access. Some devices may still have AUX port. For 2960x switches, AUX port is gone.

    1. You are asking "You have the driver for the mini USB port of the Juniper SRX ?"

      No, I do not have specific driver for SRX Mini USB port. I have cisco mini usb driver and it should be same, should not it?

    2. Google 'CP210x VCP USB Console Driver', you should get lots of links to download it. But I am not 100% sure this is exactly you are looking for.
