UCSI PPM failed to complete UCSI command in a timely manner. Please contact UCSI device or system manufacturer to investigate.

Since the 40-second EC reset did not help, re-enumerate the UCM-UCSI device in Windows, then install the latest FA507NUR BIOS and ASUS chipset-related drivers.

1. Reinstall the UCSI device

1. Disconnect all USB-C devices, docks, displays, and adapters.
2. Right-click Start → Device Manager.
3. Expand Universal Serial Bus controllers and, if present, System devices.
4. Find UCM-UCSI ACPI Device or UCSI USB Connector Manager.
5. Open Properties → General and note the Device status/error code.
6. Right-click the device → Uninstall device.
   • If offered Attempt to remove the driver for this device, leave it unchecked initially.
7. In Device Manager, select Action → Scan for hardware changes.
8. Restart Windows and check whether the warning icon returns.

Uninstalling and scanning for hardware changes makes Windows recreate the device instance and reload its driver stack ^1^.

The timeout message means a UCSI command did not receive a timely firmware response; it does not by itself prove whether the problem is BIOS/EC firmware or hardware ^2^.

2. Update the ASUS firmware and platform drivers

If the warning returns:

1. Connect the laptop to AC power.
2. Open the model-specific FA507NUR ASUS support page ^3^.
3. Verify that the selected model is exactly FA507NUR.
4. Compare the BIOS version offered there with the version shown by:
   • Press Windows+R
   • Enter msinfo32
   • Read BIOS Version/Date
5. If ASUS offers a newer BIOS, follow ASUS’s instructions to install it. Do not interrupt power during the update.
6. From ASUS’s download center, install the current model-specific chipset and any USB/Type-C or system-control packages listed for the FA507NUR ^4^.
7. Restart and inspect the UCSI device again.

This part is important because Windows supplies the UCSI driver, but the USB-C connector logic and ACPI communication are implemented through the laptop’s BIOS/embedded-controller firmware ^5^.

3. Isolate an accessory or port problem

After Device Manager shows no warning—or if the warning occurs only when something is attached:

• Test with nothing connected to USB-C.
• Connect the device directly rather than through a dock or hub.
• Try another known-compatible cable.
• For video, ensure the cable, adapter, and selected USB-C port support the required DisplayPort Alternate Mode.
• Test each USB-C port separately, if the laptop has more than one.

USB-C cables and ports do not necessarily support the same charging, video, USB4, or Alternate Mode capabilities ^6^.

When to contact ASUS

Contact ASUS service if the UCSI warning returns with nothing attached after:

• Device re-enumeration,
• the latest FA507NUR BIOS,
• ASUS chipset/system-control drivers, and
• the EC reset already completed.

Provide ASUS with:

• The exact Device Manager error code and full Device status text.
• Current BIOS version.
• Whether both USB-C ports are affected.
• Whether charging, data, and video all fail or only one function.
• Whether the error appears immediately after startup with no USB-C device attached.

At that point, ASUS must distinguish an EC/BIOS firmware defect from a USB-C controller, port, or motherboard fault. A Windows reinstall is not the appropriate next step unless ASUS or Microsoft diagnostics separately identify Windows corruption.
