+### Troubleshooting
+
+Find the InputPlumber version:
+
+```bash
+inputplumber --version
+```
+```
+inputplumber 0.58.7
+```
+
+Start InputPlumber with debug logs enabled.
+
+Temporarily:
+
+```bash
+sudo systemctl stop inputplumber
+sudo LOG_LEVEL=debug inputplumber
+```
+
+Permanently:
+
+```bash
+sudo cp /usr/lib/systemd/system/inputplumber.service /etc/systemd/system/
+sudo sed -i 's/LOG_LEVEL=info/LOG_LEVEL=debug/g' /etc/systemd/system/inputplumber.service
+sudo systemctl daemon-reload
+sudo systemctl restart inputplumber
+```
+
+View debug logs:
+
+```bash
+sudo journalctl --unit inputplumber.service
+```
+
+List managed devices:
+
+```bash
+inputplumber devices list
+```
+```

+
+Change the intercept mode of the first device:
+
+```bash
+inputplumber device 0 intercept set --help
+inputplumber device 0 intercept set $MODE
+```
+
+View what InputPlumber profiles are loaded and what event interfaces are being used:
