my keystation 88-ii doesn't work with any usb cables

my keystation 88-ii doesn't work with any usb cable or device, except for one. when i plugged it in using that one, the lights flashed on and off, green to red, except for when i pushed it in to the usb slot with force, but even when it worked and showed up in the computer devices, it couldnt read or understand it and didnt receive any midi signal

electricity at least goes through all usb cables i try, because they successfully powered the keyboard

    Hey Ethan,

    Thanks for posting!

    Sorry to hear that you are having trouble. From your description it sounds like the Keystation's USB port may be partially damaged. The USB port receives and sends MIDI data on different pins than the power. For this reason, if the data pin is bent or broken, power will still be supplied but the controller will not communicate with your computer.

    Since this may be hardware related, I suggest contacting our support team for further assistance. 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.


    • 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.
