We're trying to sandbox our app to submit it to the Mac App Store (for the first time). It makes hard use of the lower level Carbon APIs and cannot operate the other way.
When I enabled the sandboxing, some features stopped working and I see this message in the log:
9/14/12 10:51:58.863 PM sandboxd[41243]: ([41237]) MouseRecorder(41237) deny hid-control
Is there any hidden entitlement I could use or we have no chance in the App Store with this app?
Even tho I'm several years too late, I assume I can help others looking for the same. It's taken me days wondering why I couldn't connect to the keyboard. Today, the thought of the sandbox hit me, and I finally allowed my app access.
As described here, I added the following to the .entitlements file, and got access.
<key>com.apple.security.device.usb</key>
<true/>
To be specific, and not mislead:
I do not use Carbon; I use IOKit.hid, with Swift.
EDIT: See the new accepted answer
Just to answer my own question – it's not possible, there is no workaround and it's unlikely it will be possible in the future.
