Dell XPS 13 9340... thunderbolt controller not listed in device manager or system info

If a computer is equipped with a Thunderbolt controller… is it always the case where that thunderbolt controller should appear in “Device Manager” (under “System Devices”)? Furthermore, should a thunderbolt controler also use IRQ’s and therefor be revealed under “System Info” (under “Hardware Resources” > “IRQs”)?

I am concerned my brand new Dell XPS 13 9340 does not have the Thunderbolt controller I expected whe I ordered it.

I am trying to get the “Thunderbolt” controller to show up in “Device Manager” (under “System Devices”) as well as in “System Info” (under “Hardware Resources” in “IRQs”).


Do you have a Thunderbolt device connected? For me the “Thunderbolt™ Controller” only shows up in the system devices list once a dock is connected

In both cases, they work as far as USB over USB-C supports a USB hub functionality, but not displayport ports.

USB4 is compatible with Thunderbolt3 -- USB4 is NOT thunderbolt(TM)

For comparison…

(granted the HP EliteBook 840 G8 is much much much older then the Dell vampire bleeding edge XPS 13 9430 laptop)

The EliteBook 840 G8 has a true blooded
“Intel Certified Thunderbolt™” controller

Windows 11: “Device Manager” always 100% shows “Thunderbolt™” likewise “System Information” > “Hardware Resources” > “IRQs” always 100% shows “Thunderbolt™”
