macOS Monterey USB ports issue


Are USB ports not working on MacBook ever since you updated to macOS Monterey? USB hubs fail to recognize your external devices such as SSDs? This is a serious macOS 12 bug! It’s a widespread issue, especially amongst M1 Mac owners, but not only.

USB Ports Not Working On Mac

USB hubs not working in macOS Monterey

This important issue has been reported by several users on our macOS Monterey 12.0.1 review page:
Apri complains:

“2 days ago, I updated my MBA M1 to MacOS 12.0.1. After that, my usb hubs don’t work. It delivers power, but not data.”

Danielle confirms:

“Just updated to Monterey 12.0.1 and its not recognizing my external hard drives.”

I’ve researched this issue and found numerous similar reports on:

  • Apple’s Developer Forums – These reports show that the issue surfaced ever since the beta testing stages, but Apple seems to have failed to patch it for the public release.
  • Apple’s Discussion Forums – a recent thread started yesterday.
  • Reddit – user complaining that he is not able to use his mouse and keyboard anymore because USB hub fails in macOS Monterey!

    If you heavily rely on USB hubs and read this article in useful time, don’t update to macOS Monterey just yet! Prevention is the only solution at this moment!

    According to iPhoneTricks.org reader Apri, Apple is aware of this issue and plans to fix it in an upcoming software update.

    What’s worrisome though, is that the macOS Monterey USB bug has surfaced since the early betas and Apple has failed to find a solution during several months of beta testing. Hopefully, they will come up with a fix soon!

    macOS 12 USB Bug Workaround

    After reading tens of reports I can conclude that a bug causes macOS Monterey to stop supporting a large number of USB hubs. Some will work though, but not with all ports on the hub, while for others not ports work at all!

    For example, USB-C & HDMI ports might work, but in general most USB 3.0 ports don’t work! These ports do power devices. They will for example charge an iPhone, but the device won’t be able to transfer any data to your Mac. The same goes for external SSD drives and more.

    Does Your USB Hub Work?

    So, the only way way that you can get around the macOS Monterey USB issues is by trial and error.

    Bryan confirms that only one of his USB hubs are working after macOS 12.0.1 update and that’s the Vava dock. You can grab one from Amazon.com:

    Potential Fix For USB Hubs Not Working

    (Updated, November 11)
    Oliver suggests that the actual hub might not be the issue, but the cables that are being used to connect.

    “After a few days of testing I have managed to get my devices and hubs working by connecting to them with USB-FI certified USB-C 3.1 (or USB 3.0 Type-A) gen1 cables. It seems that anything else would only let them connect at USB 2.0 speeds (and some of my devices don’t work with USB 2.0, so don’t even connect).”

    If you have the available cables, test it out and let us know.

    Tip: You can quickly purchase the mentioned USB cables on Amazon: USB-C 3.1 (gen 1) cables or USB 3.0 Type-A gen 1.
