Thanks for the recommendation! It will take more time to move to the IOUSBHost framework. We'll check on that. In regards to your entitlements recommendation, we added "com.apple.security.device.usb" entitlement to our .app and helpertools as well and verified the same after notarization. However, we are getting the same error message. Would it help if we share some logs? If yes, can you recommend any specific command we should run to fetch the logs?
