https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D244517 --- 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 a= nd confusing hardware design decisions with TB3 that make it hard to work with= .=20 I'm finishing up a driver right now and intend to make it available for tes= ting in the next few days. In the mean time, I recommend that you open up the B= IOS 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 sim= ilar words. You can try setting the security model to "none" and see if that al= lows your USB hardware to show up when you plug it in. Even if it does, there m= ight 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 upd= ate this bug report once I have some code that can be tested. --=20 You are receiving this mail because: You are the assignee for the bug.=
