Just switched HP laptops and at same time, Win10 -> Win11. I have an HP ZBook Firefly 15" G8, along with a Plugable TBT3-UDZ thunderbolt dock. Attached to the Plugable dock is a DisplayPort external monitor, ethernet, and a USB 2.1 switcher. Attached to that is a wired keyboard, a wireless mouse (Logitech) dongle, and normally a Logitech Brio webcam.
Problem Statement: At boot up, the Thunderbolt dock is not authorized. Only way to unlock computer is to move webcam directly to USB-C port on laptop, and use internal keyboard/mouse. Alternative is to disable thunderbolt in HP bios so external port is USB-C only, unplug/replug Pluggable TBT3-UDZ so it sees it as USB-C instead of Thunderbolt. Then I can use dock at boot up.
In Windows 11 Thunderbolt Control Center when HP in thunderbolt mode, the TBT3-UDZ device shows up. But the new control center does not provide anyway to authorize the device so it becomes a known and trusted device. Going to the Authorize Devices menu just says devices will automatically be connected, which is kinda the problem because they only automatically connect AFTER I authenticate, which I can't use the devices attached to the TBT3-UDZ to do that.
In Windows 10 I could authorize this particular Thunderbolt dock as trusted. Any new device should be blocked unless I had unlocked my machine to prevent unauthorized access, but if it is my dock, I should be able to use it to unlock my machine.
