Use Device Manager to confirm driver installed and device shows correctly with no warning icons.
Test with vendor application configured for exclusive mode. Attempt to open device simultaneously from a second application — the second open should fail if exclusivity enforced.
Use Sysinternals Process Explorer or Handle to confirm only one process holds a handle to the device.
Check Windows Event Viewer (System/Application) for driver or application errors.
