Hi username01,
Thank you for your message.
We’re sorry to hear that you have issues to unlock Cubasis LE with the iRigh HD2 over USB-C.
The issue sounds similar to a known Apple issue, which will be fixed in their upcoming iOS / iPad OS 13 release.
Please note that I’ve send you a private message, to have you supported in solving the issue before Apple’s iOS / iPad OS 13 release.
Best wishes,
Lars
