Hi jakaandrianto,
Thank you for reaching out Microsoft Community. We're sorry for the inconvenience this has caused you.
Are you trying to download and update the associated app for this ethernet adapter to work? If the app that supports this kind of adapter only runs on x64-bit, then this won't work on a Surface Pro X with ARM processor. So, what I can highly suggest is to contact the software developer to check if they do have an updated software for this adapter that runs on X-86 bits or an associated software that is ported to ARM64.
Is this similar to a USB-C to ethernet adapter from this link>> https://www.microsoft.com/en-us/p/surface-usb-c-to-ethernet-and-usb-adapter/8wt81cglrblp?. If it is and it won't work on your Surface Pro X, what I can recommend to try it on another device. The issue why it isn't working might be due to not being compatible to a device with ARM processor.
If this helps, feel free to mark this post as an answer. Otherwise, don't hesitate to respond to this thread and let me know if you have tried using this adapter to another device.
Kind Regards,
