A peripheral or feature that disconnects and reconnects on a computer is usually a power-management or driver-timeout setting, not failing hardware. For BitLocker recovery, first identify the recovery-key ID and check the owner’s Microsoft/work account records.
What this covers
- BitLocker recovery with this exact failure state
- Diagnosis across legitimate device ownership/key record versus firmware, account and hardware changes

ReversibleNote whether the drop correlates with sleep/wake, a specific USB hub, or sustained heavy use. Expected behavior: unlock the encrypted system with the correct recovery key after a trusted-state change.
Isolate the component boundary
ReversibleIdentify the recovery-key ID and check the owner’s Microsoft/work account records. Test the device on a direct port with no hub, and disable USB selective suspend for that port. Boundary to separate: legitimate device ownership/key record versus firmware, account and hardware changes.
Correct only the proven cause
ReversibleUse the matching key, restore trusted boot settings or involve the organization administrator. Disable the power-management setting that turns the device off to save power, or update the controller driver.
Verify and stop safely
ReversibleRun the device under the same load that triggered the drop for at least 30 minutes. Never share recovery keys or erase the drive until data-loss consequences are accepted.
