do this device or any other works with opensuse?
I don't understand what the device does.
Depends what functionality you're going to use. Extra USB ports, audio and ethernet will likely be okay, but notably, you might have issues with the display output. It uses DisplayLink. From playing around with a couple of docks recently I've found that to be terribly unsatisfactory.
So it connects to a computer via USB3 and provides USB3 to others, like an USB3 hub. But it also provides sound. A speaker, then? Same sound as the computer, or different?
There's no official DisplayLink package for openSUSE, but somebody has packaged it in an OBS home repo. I tried it out. Got all sorts of weird and undesirable visual artefacts, glitches and odd behaviours. When seeking advice elsewhere online, others advised me that it's effectively a technology that tries to cram potentially huge graphics signals down a constricted pipe, and has to compress things in such a way that these artefacts are very probable.
Same video as the computer? Can these things show a different audio and video than the computer? For example, use it to display a movie or the TV while one continues working at the computer. Or have it show a display at a shop, maybe several slow displays, while the computer is at the desk, being used. It might be more interesting to connect via Ethernet, longer distances in a shop.
I bought an alternative dock with both HDMI and a VGA port that does up to full HD 1080p which is all I need, hoping that might work better, but neither work by default in Linux, despite it being a dock that explicitly advertises itself as Linux compatible. Hence I'm not at all impressed with the state of play of generic docks on Linux. You really need either a dedicated dock for a traditional laptop, or Thunderbolt. Trying to connect additional displays via either USB A/B, or basic USB-C without Power Delivery or alt-mode capabilities, doesn't seem to work well.
