Task guide Inspect Connected Devices Before Changing Anything
Use this when a keyboard, mouse, webcam, drive, or other device is not behaving the way you expect.
Device problems become messy when people jump from symptom to repair without confirming whether the device is detected at all.

Safe first move Inspect first, change later. Do not uninstall or disable devices before you inspect the state.
Use this when Use this when a keyboard, mouse, webcam, drive, or other device is not behaving the way you expect.
Goal
Determine whether the machine can see the device before you try to repair it.
Safe sequence
- inspect the device list
- look for a useful status clue
- decide whether the likely layer is connection, detection, driver, or app use
- stop before changes
Windows notes
Get-PnpDevice is a good read-only starting point.- Error state is already evidence. Do not rush into driver changes.
Linux notes
lsusb, lspci, and recent dmesg output can help show whether the machine noticed the device.- Detection first. Repair second.
Move on when
- you know whether the device is detected
- you can name the likely problem layer
- you can explain the next safe step
Before you start - Inspect first, change later.
- Separate connection, detection, and driver state in your head.
- Prefer read-only device listings.
Verify with - You can tell whether the system detects the device.
- You can identify one useful status clue.
- You can choose a safer next step.
Avoid these mistakes - Do not uninstall or disable devices before you inspect the state.
- Do not assume the driver is the problem if the device is not detected at all.
- Do not keep reconnecting without checking what the system reports.
Move on when - You can inspect connected devices safely.
- You can explain why detection comes before repair.
- You can pick a small next step instead of guessing.
Reflect before you leave - What clue told you the device was or was not detected?
- What would have been risky to do first?
