What This Guide Helps With
Error #000000014 indicating USB hub failure causing loss of peripheral communication (modules, printer, or accessories) and possible device functionality limitations.
Step-by-Step Troubleshooting
1. Ensure Patient Safety
- Remove the monitor from active patient use if accessory communication is required for care (e.g., NIBP, SpO₂ modules).
- Expected: Patient safely transferred to another functioning monitor.
- Why it matters: Loss of module communication can result in incomplete or missing vital signs.
2. Verify the Reported Error and Behavior
- Power on the device and confirm Error #000000014 is displayed. Observe:
- Does the error appear at startup or during use?
- Are accessories (SpO₂, NIBP, temperature, printer) not recognized?
- Are ports non-functional or intermittently working?
- Expected: Error is reproducible and one or more USB-based peripherals are not functioning.
- Why it matters: Confirms a true USB communication failure vs accessory issue.
3. Perform a Full Power Cycle
- Shut down the monitor, disconnect AC power, and remove the battery (if accessible). Wait 30–60 seconds, then restore power and restart.
- Expected: Device boots normally and error may clear if transient.
- Why it matters: Resets internal communication buses, including USB hub initialization.
- If error clears → Return to service
- If error persists → Continue
4. Check Connected Accessories and USB Devices
- Disconnect all external accessories and modules (SpO₂, NIBP hose/module, printer, USB devices). Restart the monitor with no peripherals connected.
- Expected: Device boots without error if caused by external device conflict.
- Why it matters: A faulty accessory can overload or disrupt the USB hub.
- If error clears → Reconnect devices one at a time to identify faulty accessory
- If error persists with nothing connected → Continue
5. Inspect External Ports and Connections
- Visually inspect all USB and module connection ports for:
- Bent pins
- Debris or contamination
- Physical damage
- Expected: Ports are clean, intact, and undamaged.
- Why it matters: Physical port damage can mimic internal hub failure.
- If contamination is found → Clean carefully and retest
- If damage is found → Remove from service
6. Check for Peripheral Power Indicators
- Reconnect a known-good accessory (e.g., SpO₂ module) and observe:
- Does the accessory power on?
- Is it detected by the system?
- Expected: Accessory powers and is recognized.
- Why it matters: Helps determine if the issue is power delivery vs data communication.
- If no power or recognition → Strong indication of internal USB hub failure
- If intermittent → Possible internal board instability
7. Attempt Software Restart / Configuration Reset (If Available)
- If accessible through system settings, perform a soft reset or restart of system services.
- Expected: Temporary communication faults may clear.
- Why it matters: Rules out software-level USB communication issues.
If the Problem Persists
If Error #000000014 continues after:
- Power cycling
- Removing all accessories
- Verifying ports and connections
This strongly indicates internal main board USB hub failure.
Action:
- Remove device from service
- Label as Out of Service
- Send for repair or board-level evaluation
Reinforcement:
Knowing when to stop prevents unnecessary risk and is proper troubleshooting.
Clinical Use Tip
Do not rely on a monitor that cannot communicate with its modules—missing vitals or delayed readings can directly impact patient care decisions.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Unit displaying Error #000000014. Accessories not recognized and unable to obtain vital signs."
Cause
What was observed during troubleshooting.
Example:
"USB hub communication failure. External accessories and connections ruled out. Issue isolated to internal main board."
Resolution
What action was taken.
Example:
"Performed power cycle, disconnected all accessories, and inspected ports. Error persisted. Unit removed from service and sent for repair."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Error codes like USB hub failure are strong indicators of internal communication breakdown. Always rule out accessories first, but escalate appropriately when the system confirms hardware failure. Patient safety depends on reliable data acquisition.
That is successful troubleshooting.
