After updating to Tahoe, USB devices connected via USB hub are no longer recognized

As the title says, after updating my Macbook Pro to Tahoe neither my external mouse or keyboard are being recognized. They are both connected via a port hub that is also used to connect the external monitors, which work fine.

You do not say what specific " port hub" this is ...(?)

Did you search the developers website or contact their: Support/Help/FAQ/Known issues/compatibility/updates…

a possible firmware update may be available for comparability..?

Otherwise shutting down and restarting with your device plugged in and compare your results.

>Shut Down...

if no resolve—

To be proactive you can file a bug report / submit your Apple Feedback here: Product Feedback - Apple

Sorry, it's an MCY Docking Station that I bought from Amazon back in 2021. There's not much in the way of a product support page for it or anything in the line of firmware updates. However, it's worked fine without any specific tweaking up to this point. I've also restarted it with the hub plugin and my USB devices still were not working.

see if this is it...

I'm having a similar problem with an OWC Thunderbolt dock, although it only afflicts my iPhone. Since the Tahoe update, my phone is not mounted by Finder (although it does charge) and is not accessible by Image Capture or Xcode. Yet a thumbdrive plugged into the dock mounts just fine.

Plugging the phone into the computer with the same cable causes it to mount, so it's not the cable.

I do experience the same issue. I have a MacBook Pro M4 and after I updated to MacOS 26 my monitor and webcam which are connect via Satechi Thunderbolt 4 Dock Slim Hub Pro are not being recognized anymore.

When I plug the monitor into my MacBook directly it works however I use my Mac in clamshell mode so my whole setup is messed up now.

I just updated to MacOS 26.0.1 but the problem still persists.

After the 26.0.1 update the audio through my Thunderbolt dock because unusable... full of pops and drop-outs.

At that point I shut the computer down and unplugged the dock from power, then plugged it back in and restarted the Mac.

This seems to have resolved everything; audio is OK now, and my iPhone mounts (which would not before).

Having a very similar issue right now. Just updated to Tahoe 26, and my Baseus multi-port usb-c dock which was working absolutely fine just stopped being detected post update, immediately. Non-existent in the system report.

Every single peripheral is connected to that dock, now im currently on hdmi to a monitor and connecting my keyboard directly to my Mac mini to type this.

Mac mini 2024 , M4 Pro.

Any fixes yet?

Same here with Nedis USB-C 7 port hub, working fine on Sonoma, but after update to Tahoe no longer working. Tried every obvious solution (reboot- disconnect hub - reconnect etc). Usb-C hub is visible in system properties and also usb-drives connected to hub are visible there. However in finder they are not showing as external drive (the setting to show external drives in finder is ticked). apple device is iMac M1. update to MacOS 26.0.1 did not solve the issue.

Have a CalDigit Thunderbolt 4 Element with ext. Drives for back up connected to a MacMiniM1. Since Tahoe after automatic backup + unmount + PowerOff the drives AND then PowerOn the next day the drives are not recognized. Not in Diskmananager etc.

After restarting the Mac the drives appear. Backups etc. run fine.

back-up ends+unmount+poweroff I cannot get access back until restart…

sounds like the same sort of issue mentioned here

br -T.

I am on an M1 Mac Studio, and nothing gets recognized through a USB hub after the Tahoe update.

Just seeing the "Accessory Not Enabled" notification, which I believe is due to the hub having an HDMI port. However, none of the USB ports are showing up either.

I found a similar problem with my Anker 563 USB C 10-in-1 docking station. Ports for my monitors worked but the USB A for my Akai MPK259 stopped working. I can plug the Akai directly into my MacBook Pro with the media adapter and it works fine. Restarting the hub and the Mac do not solve the problem. I've update the firmware for the Akai and updated the DisplayLink Manager app to 14.0.0 (build 7). The problem remains.

I found a workaround that is working consistently for me:

1. Connect Macbook to (Thunderbolt) hub via cable
2. The monitor is not being recognized, which prevents you from using clamshell mode.
3. Open up your Macbook, while still connected to your hub and do a normal restart.
4. Once you log in, your monitor should now be recognized by your Mac and you should be able to use it in clamshell mode.

This worked for me but it's not a longterm solution. Let's make sure to flag this to Apple so they are aware.
