https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244517 --- Comment #4 from Scott Long <scottl@FreeBSD.org> --- Hi, I'm assuming that this is a Thunderbolt 3 port, since it's a USB-C connector and your devices aren't showing up in the OS. There are some unfortunate and confusing hardware design decisions with TB3 that make it hard to work with. I'm finishing up a driver right now and intend to make it available for testing in the next few days. In the mean time, I recommend that you open up the BIOS on the laptop and see if there are any controls related to Thunderbolt 3. If there are, you might find a control for the hardware security model, with options for "none", "user", "display port", and "key exchange", or some similar words. You can try setting the security model to "none" and see if that allows your USB hardware to show up when you plug it in. Even if it does, there might still be some problems with the hardware not working or invoking endless internal resets, but it'll at least be some good data to collect. I'll update this bug report once I have some code that can be tested. -- You are receiving this mail because: You are the assignee for the bug.home | help
