scrcpy access problem with Linux

I have 2 Android devices: a tablet from Denver and a cell phone from Xiaomi (Redmi 9C), I installed scrcpy on my MX Linux pc, I have no problem to access tablet through scrcpy, but when I tried with Redmi 9C, I can only see it, the mouse does not work, did I miss some settings? The developer option is enabled (is there any other options inside developer options that I need to change/enable? I only enabled developer options). note: 1) I've tried enable file transfer when plugin the USB cable, seems to make no difference and adb device command can see this device. 2) adb version 1.0.41
