Herelink Controller unit - USB tethering using a Raspberry Pi 4

I can successfully connect Herelink Controller Unit (HX4-06075) to a Linux desktop PC via USB tethering.

However, when connecting the controller unit to a rasperry pi, “USB tethering” stays grayed out (“USB not connected”) and only charges the controller unit.
The device does not show up as a network controller on the pi as well.
I’m using the latest Raspbian (Debian bullseye) image without any modifications.

Any hints how to use USB Tethering with a Raspberry Pi?
