I have an app that needs to seize USB devices, in particular it needs the USBInterfaceOpenSeize call to succeed. I've got a provisioning profile with this entitlement, I've added this plus this entitlement to my app but the USBInterfaceOpenSeize still fails. Am I correct in thinking this is the correct/only entitlement I need for this? If so how do I check if I'm using the profile/entitlements correctly? The call succeeds if I run the application as root which makes me think it's a permissions issue. Thanks.
