Hello, We asked Apple if it is possible to use our iPad USBDriverKit driver on the iPhone 15, and they told us that it is not supported.

This was our problem indeed. Although not conformant to the Apple specs, it used to work, and it wouldn't since Ventura. Thanks Eskimo for the help on that.

No, we had no contact with this person. However, I have no doubt that, if he is using smart cards for his auth, and it used to work and not working anymore with Ventura, it is the same problem: basically, CryptoTokenKit smart card drivers don't work at all anymore, so it is easy to diagnose. By the way, I had no response from the feedback I sent through the assistant. This is becoming critical now that Ventura is out. Is there any way to push this, either from my side or your side? Thank you.

Hi, thank you for your interest in this. I was kinda hoping you would hop in... The feedback ticket is FB11675669 (https://feedbackassistant.apple.com/feedback/11675669). For information, the CryptokTokenKit is still called successfully when the card is inserted, and we can return some certificates when the smart card content is queried, but it is never called later when an application tries to make use of KeyChain APIs. All the calls we see are successfull, and seem to return the correct information, but it just goes blank at some point.
