Hi Terry Junge，
I have made the changes as per your suggestion. mic.txt is the microphone report descriptor and is working properly.
Thank you,
I can confirm that this latest patch fixes the issue on my GPD Duo.

Hi Zhang,
Since the manufacturer has verified that all the microphones have the same serial number you could add the test for that as well if you want.
The report descriptor is clearly for a keyboard/keypad and should be ignored.
In any case, the current v3 attached patch does resolve the conflict.
