The USB device might be failing.

Complete the following steps:

Does the location in the service action log for this field-replaceable unit end with -Cx or -Dx?
- Yes: Replace the USB device at the location indicated. For more information, see Part locations and location codes. Select your machine type and model number to find more location codes, part numbers, or replacement procedures for your system. This ends the procedure.
- No: Continue with the next step.
Was the serviceable event logged by the adapter resource?
- Yes: Determine the location of the port by removing -Lx from the location code. Use the USBPORT symbolic FRU to determine the location of the USB port that the device is attached to. Replace the device at the port location. If there is no device at the port location, trace the USB cable at the port location to the device and replace the device. For more information, see Part locations and location codes. Select your machine type and model number to find more location codes, part numbers, or replacement procedures for your system. This ends the procedure.
- No: Continue with the next step.
Find the product activity log for the system reference code (SRC) by completing the following steps:
1. Select System Service Tools (SST).
  If you cannot get to SST, select DST.
  Note: Do not perform an IPL of the system to get to DST.
2. In the Service Tools display, select Start a service tool.
3. In the Start a Service Tool display, select Product activity log.
4. In the Product Activity Log display, select Analyze log.
5. In the Select Subsystem Data display, select All Logs.
  Note: If the SRC you are using occurred more than 24 hours ago, change the from and to dates and times from the 24-hour default.
6. Use the defaults on the Select Analysis Report Options display by pressing Enter.
7. Find the entry in the product activity log that matches the SRC.
Select the Display Detail Report on the Resource display.
Press F6 (Hexadecimal report) to display the hexadecimal information of the product activity log.
Look for the first occurrence of 0A77 in the hexadecimal data between offset 00019E and the end of the hexadecimal data.
Record the hexadecimal digit that immediately follows the 0A77 digits. This hexadecimal digit is the logical USB port number.

Use the following table to determine the physical USB port location. Replace the device at the port location. For more information, see Part locations and location codes. Select your machine type and model number to find more location codes, part numbers, or replacement procedures for your system.
