What does all green leds blinking mean in USB mode in a Midisport 8x8?

I've been using a Midisport 8x8 flawlessly for many years. Today, when turning on the unit in USB, all green leds started to blink instead of the usual green led glowing and pulsing. I assumed it indicated a faulty USB connection but I have checked and it's Ok. No changes in the computer for months, not even OS upgrades. What is the unit diagnosing with all those leds blinking?

Ah, by the way, the unit is working correctly in standalone mode.

Thank you very much for your help.

  • Hey Carlos,

    Thanks for posting!

    If the MIDISPORT is functioning in standalone mode that is a good sign! With that in mind, it is possible that the problem could be relative to the USB connectivity or the power that is being provided to the interface.

    I'm not sure which operating system you are using just yet but let's ensure that you have a clean installation of the latest available driver installed for whichever OS you are using. The MIDISPORT 8x8 is supported for use up to Windows 10 and Mac OS X 10.8.5 with the following drivers:

    M-Audio MIDISPORT 8x8 Driver (v6.1.3) - Windows

    M-Audio MIDISPORT 8x8 Driver (v3.4.0) - Mac

    First, remove any 8x8 driver you currently have installed on your computer. When that process is complete, restart the computer. Now, download and install the driver for your OS from the links above.

    If you're still having trouble connecting, try and test the USB connectivity. I understand you've already checked this to some degree but I'm not sure what you've done specifically. Try connecting with a different USB cable, with different USB ports on the computer, and a different computer to see if you can reproduce the same behavior. Be sure to connect the MIDISPORT directly to the computer via USB and avoid using any USB hubs or adapters. Depending on your operating system, you may also want to see if the USB drivers can be updated - please refer to your operating system's documentation for information regarding updating system USB drivers.

    If you have tried the above steps and you are still unable to use the 8x8 correctly, this sounds like it could be related to the hardware's USB port. Warranty and non-warranty claims cannot be handled here on the forum but I can point you in the right direction! Here are a couple of options that you could choose from:

    • Submit a Warranty or Service Inquiry with our Technical Support team by logging onto the M-Audio Support Page. Select Warranty or Service Inquiry from the drop down menu. This will not require a support code.

    or

    • For faster support, call or email your nearest Support Office or International Distributor. Select your country to find the nearest office.

    Make sure to reference or link to this thread to help out the support team.

    I hope this helps! Let me know if you have any additional questions.

  • Thank you very much Nick. The problem was solved by installing the driver. But the process is rather mysterious... I have 2 MIDISPORT 8x8 which I had used with the same driver in a PC with Windows 8.1 That PC is not connected to the Internet in order to ensure a stable behavior. No application had been installed or upgraded in the last year. I suspected that the unit was malfunctioning so I replaced it with the other. I switched it on and, as I expected the USB led started to glow and with a steady pulse. However, a message appeared in the PC warning that a USB driver was not working properly and had been deactivated. How is that possible? Same configuration of a PC used on a daily basis and all of a sudden, Windows doesn't like a driver that had been working flawlessly for 3 years... So, I accepted the mystery, followed your instructions, installed the new driver and problem solved. Thanks again.
