Vid/Pid 0489/e0f1 is a MT7922 module for Windows PC. We'll recommend that you can send a patch to support MT7922 Bluetooth module with 0489/e0f1 by yourself if you needed. Otherwise, you have to wait until there is a linux project adopted with the same module in the future. I'll also let my manager aware of such support problem that user changing OS from windows to Linux. Sorry for the inconvenience. BRs, Chris >
