Fallback to default keyboard injection method (-K/--hid-keyboard ignored

hello, I'm using lubuntu and I wanted scrcpy it won't let me use the --otg or -KM option in any way
someone could help me?

scrcpy 1.24
/usr/local/share/scrcpy/scrcpy-server...hed. 6.0 MB/s (41159 bytes in 0.007s)
[server] INFO: Device: TCL 5048A (Android 9)

The report concerns scrcpy 1.24's -K/--hid-keyboard, -M/--hid-mouse, and --otg/-KM options; start by reproducing the logged fallback on Lubuntu with the listed Android 9 device. Trace the option handling and USB-device detection, then confirm done when the requested HID/OTG mode works or the unsupported condition is clearly reported.
