ASR920 and USB Console

Hi all,

  Having an issue getting a console connection into my ASR920.

Using Putty and keep getting the "Unable to open Com port" window...

So, in other words, the Putty window doesn't even open.

All Putty setting are correct i beleive, serial connection and try multiple diff com ports (com1, 2, 3, etc...)

I installed the asr-9xx_usbconsole_drivers and still nothing.

Have tried this now on 2 different laptops.  One running Win10 and the other Win8.1.

Both laptops run Putty just fine connecting into everything else (with the rj45 connector cable).

Also am using a USB typeA to typeA cable for the ASR.

Any ideas???  Do I need to order a special Cisco branded USB cable?

Any help is appreciated...this thing is killing me.

Does the ASR have multiple USB ports on it?  Typically on the few platforms that do support the USB console, the USB console is the Micro-USB or Mini-USB port - and the type A is for a USB stick for loading images or saving configs.

Thank you for the reply.  The ASR920 requires a Type-A to Type-A cable for the console connection.

Not sure if you solved it yet however.

 

You are using the USB port at the bottom right of the unit?
That port is for console when using the USB/serial drivers "asr-9xx_usbconsole_drivers"

Once you plug it in to the ASR and your PC, you should get a "USB UART"  show up in your device manager under ports for the PC.

 

The "console" port on the bottom left, should be for proper serial connections. the same as any garden variety cisco router except it uses a USB for the interface port.

Hi,

It is necessary to get and install this driver:

asr-9xx_usbconsole_drivers.zip

https://software.cisco.com/download/home/286037604/type/282855122/release/3.13

using usb type A on both sides, configuration on putty as usual
