Xcodebuild command not Listening to USB

Hi, I setup mobile environment as per all the instructions but when I finally run this command "xcodebuild -project WebDriverAgent.xcodeproj -scheme WebDriverAgentRunner -destination ‘id=’ test" with udid replaced with my iPad udid, then I do not get “Listening to USB” when Test Cases Start running. Instead I get “Using singleton test manager”. Because of this reason or may be another reason, Katalon is not listing my device name.
When I run following command, my device id is listed:

**cd /Applications/Katalon\ Studio.app/Contents/Eclipse/configuration/resources/tools/imobiledevice **

**idevice_id -l**

I am attaching the screenshot which shows the messages displayed after running xcodebuild command.
