Prevent iTunes for activating devices
If your Mac is running Mac OS 10.13.x or earlier, you must tell iTunes to stop trying to activate devices. This step is not required for Mac OS 10.14 and later.
Open iTunes, then open Preferences > Devices.

Check the box “Prevent iPods, iPhones, and iPads from syncing automatically.

Close Preferences, then quit iTunes.
Allow GroundControl to use a Proximity Badge Reader
Macs running recent operating systems may display an additional security prompt. “Applications” would like to receive keystrokes from any application. This prompt appears if you are using GroundControl Checkout features, have enabled the features for proximity badge readers, and are running macOS 10.15 “Catalina” or later.

GroundControl really is not interested in keystrokes from other applications. However this is how Catalina presents requests to access USB HID devices, which appear to the Mac as something like a keyboard.
To use these devices, you must grant permission for “Input Monitoring” to the Launchpad app. Open System Preferences > Security & Privacy > Input Monitoring.

Check the checkbox next to “GroundControl Launchpad.app” to grant permission. (If needed, click the lock in the lower-left corner and enter administrator credentials). If the Launchpad app is running, the system will remind you to quit and relaunch the app.

The next time you run the Launchpad app, it will have the access to hub or card reader you expect.
