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

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).

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...

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

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.

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 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.

This issue is not only trying to connect through a dock... It also includes a direct connection with a USB cable.

I have a MacStudio and MBPro and connected them with a USB cable and when both ran Sequoia: NO PROBLEM. I could move my mouse between the two, drag and drop, etc., NO PROBLEM. Each time I connected the two computers with the cable, they were instantly connected!

As soon as I upgraded the Studio to Tahoe, BIG PROBLEMS. It no longer worked. (I was forced by Apple engineering, troubleshooting the problem with AirDrop, to upgrade.) There was no mouse movement between computers, of course no drag and drop. (Other threads are showing that "AirDrop" doesn't work anymore on Tahoe... there seem to be a pattern of problems emerging: "connectivity" and "Tahoe.")

The temporary pain-in-the-neck work around is to go to "Network", connect the two computers, then select the specific folder, and then, on the Studio, drop whatever file I need into that folder.... that is time consuming and the computers must be reconnected in this way every time I connect the computers with a USB cable. The common denominator here is OSTahoe...

Yes, for me the two issues I described: a) not recognizing a MBPro connected by a USB to a MacStudio and b) AirDrop not working, have been resolved (more or less) by upgrading Tahoe to v26.1.

AirDrop now very quickly sends the file to the MBPro, however, it still takes quite a while (10-15 seconds) for it to send a file to my iPhone 16 (iOS18.7.1) but it does send it eventually successfully.

So, while Tahoe 26.0.1 created these problems, Tahoe 26.1 seems to have solved this problem....Thus proving the old computer adage, "never install "version point 0" of anything..."

Hopefully this will also make progress on solving the docking station problems you chaps have with that connectivity issue...

I hope everybody is reporting this: Feedback - macOS - Apple

Nothing will get fixed if we don’t collectively report this bug!

My old Sabrent 36W 7 Port USB 3.0 Hub doesn't work with some older midi devices that demand power

but my newer SABRENT 7-Port USB-C Hub with Power Switches does work

The Tahoe 26.1 update resolved all the issues on my end. (MBP M1 Pro)

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.
