Issue/Introduction

We can use CA Agile Central Excel add-in. Clicking "Connect" button results in this error message:

<Please see attached file for image>

Environment

Release:
Component: ACSAAS

Resolution

This error is not a CA Agile Central error. It is not an error of the Excel add-in component either.

This error is reporting a problem with one of your USB devices that's connected to your Excel (to your Windows actually). What we found that helped resolve was:

1. Reconnect your device.  If not working with the same port, try another usb port.
2. Restart your machine.
