Hi all, here's some additional info. First a commented version of the hid-recorder dump (using https://gitlab.freedesktop.org/libevdev/hid-tools).

And I grabbed a Windows 10 computer of a colleague where the touchpad works as advertised (e.g., 3-finger swipes switch between windows) and collected the USB HID info using a tool called USBlyzer.
Attachment:
USBlyzer_Dev_Details.html.gz
Description: USBlyzer device info
Apparently, with my lack of knowledge, it looks to me as if the device would be recognized pretty much the same as here on Linux, i.e., as a mouse, a keyboard, and some consumer controller... Uhm, and in fact, also in Windows the mouse settings (like speed) affect the touchpad. The specialized touchpad settings are not shown (although googling suggest that the mouse settings should have a touchpad tab if a touchpad is connected). It seems like it probably works as good in Linux as under Windows by emulating a normal mouse, and the working 3-finger swipe switching apps in Windows is just some shortcut I could perform with a mouse, too. So it seems like I just bought a lame device, right? Bye, Tassilo
