Flutter lost connection to physical device

Issue

My physical device gets always disconnected when using flutter debug. I tried to stop and start adb server, delete the remaining app from the phone, run flutter clean, flutter upgrade (is currently on stable 1.17.5) and uncheck/check the debug settings on the phone. Before today everything worked fine and on an emulator it is still working fine.

Launching lib\main.dart on Redmi 5A in debug mode...
√ Built build\app\outputs\apk\debug\app-debug.apk.
Error: ADB exited with exit code -1

Flutter Doctor:

   [√] Flutter (Channel stable, v1.17.5, on Microsoft Windows [Version 10.0.18363.959], locale de-CH)
    [√] Android toolchain - develop for Android devices (Android SDK version 30.0.0-rc2)
    [√] Android Studio (version 3.6)

Solution

Probably a bad USB cable since ADB over WiFi works perfectly.
