USB debugging enabled

Then it might be your USB cable. Try another one with data support.

The detection is not handled by scrcpy, but by adb.

Once you can make adb devices detect your device, it will work. Are you sure USB debugging is correctly enabled? Can you detect another device on your computer?

USB debugging turned on, and last month it worked perfectly.
