USB port overflow

What does 2822 mean?

The USB port buffer has overflowed, indicating that data is being received faster than it can be processed. This can lead to loss of communication or corrupted data for USB connections.

• Data being transmitted to the USB port (e.g., from a PC-based configuration tool) faster than the drive can process.
• Corrupted USB data packets causing re-transmission and excessive buffer filling.
• High internal drive processor load preventing efficient USB data handling.
• Software driver issue on the PC or a firmware bug in the drive's USB stack.
• Faulty USB cable causing data errors and subsequent re-transmission attempts.

Click steps to track your progress.

1. 1

   Reduce the data transfer rate or message frequency from the connected PC software (e.g., MCT 10).

2. 2

   Verify the integrity of the USB cable (A-B type) and try a different, shorter cable (max 3m length recommended).

3. 3

   Ensure the drive's USB drivers are correctly installed and updated on the connected PC.

4. 4

   Update the drive firmware to the latest available version to address potential USB stack bugs.

5. 5

   Disconnect and reconnect the USB cable, then power cycle the drive if the fault persists.
