Thank you, James, Milan and others. I've run 'dmesg'. And that showed the reason.
It turns out that my ZYD is an unsupported RF chip type 5. Is there any chance for ZYD driver to support it, please? Or would it be difficult for a me as a non-driver developer to add it in (by looking at Linux drivers)?
