I meet a problem of connection. I install the driver but the computer seems not to recognise the graphic dock.
I cannot find my thunderbolt controller in the rest of picture 1, and I also cannot find thunderbolt in device manage.
does anybody know how to solve it?

as title written, TB3 cannot be found in Device Manager, while already enabled in BIOS (1.40):
The error is "no active thunderbolt controller found in this system or thunderbolt software is not present in this system"
The BIOS setting is listed here
And I can also not find Thunderbolt software in device manager. But "service" has thunderbolt service.
And there are also no thunderbolt controller

It was the recent BIOS update. If you go here:
and scroll to 1.38 (n23uj16w.exe), download and install that. (Note: you might encounter a message about Secure Rollback being enabled in your BIOS.... you'll need to disable that and try again.)
After rolling back the BIOS, I rebooted and instantly everything was working again.
[UPDATE] After doing a software update from Vantage with the rolled-back BIOS, it said there was critical Thunderbolt firmware to install. So I did that, and on a whim decided to re-update my BIOS to the newest version. Things still work! So it would appear that in both our cases, the BIOS was updated before the Thunderbolt firmware update, which lead to the problem. Had we updated the Thunderbolt first, then the BIOS, everything would have been fine.

Hi，I just follow your step and scroll my BIOS to 1.38 and reinstall thunderbolt software. But there are no change for it. I still cannot see the thunderbolt controller
