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

To follow up: Audio was NOT fixed. One cause appears to be Apple launching dozens of processes for iPhone simulators, if you have the development tools installed. There's a thread about it, and an apparent solution, here

This is the most annoying bug I ever had since I am using a Mac. Restarting it every single time when I connect it to my docking station or to an external display is a pain, but what makes me even more worried is that I cannot see that this issue has been noticed by Apple and therefore I am not sure when a fix is going to be delivered. Have you seen any update on this?

Doesn't matter.

At "Always Ask," it sees that an accessory is added, but it cannot detect anything plugged into the accessory.

I plugged the hub into a PC laptop and it works fine; detects the connected DVD drive via USB-A.

The mac does nothing after Tahoe upgrade.

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...

Same problem. I have a Hyper Drive 11-in-1 hub (model GN30B). The MBP recognizes that an accessory has been added when I plug it in, but doesn't detect a drive or a monitor connected to it.

Hub works fine w/ a PC so it's not the hub.

Massive issues for me and cannot get my system to recognize my keyboard or mouse via USB or Bluetooth. I can’t get past setup screen now and extremely frustrated. I didn’t even download the first version. I downloaded whatever version was out on Friday night and my work is at a standstill right now. I have logi keyboard / mouse and Apple ones and nothing working for me. My desktop is useless right now. Moving to an old MacBook for now with Sierra. Not upgrading to Tahoe until this is resolved.

Is there any way to address this? My Macbook has an Intel processor, so setting "System Settings->Privacy&Security->Allow accessories to connect->Ask every time" as suggested in the previous thread above isn't an option.

Bummer, man. I didn't have this particular problem (but have other Tahoe connectivity issues) and would just reiterate the good advice given elsewhere in this chain, keep complaining to Apple via the Product Feedback - Apple URL that was given earlier. And not just once. Every time you try something and it doesn't work, complain again... Create volume on the issue. Good luck!

I’m experiencing an issue with my Corsair Wireless or Wired mouse. When I switch user accounts without restarting the computer first, the mouse starts dropping selections. Returning to the first user logged in resolves the problem.

However, if I switch user accounts, the mouse begins dropping selections. For example, if I select an input field like a search bar, it behaves as if I clicked outside the bar, and I have to click it again. This is extremely frustrating when trying to type something. It also makes using dropdown menus a challenge. I’ve tried numerous suggestions, but none have worked. The only suggestion Corsair has provided is to roll back my operating system.

Any updates??? I have an Apogee Duet and a Editors Keys Ableton live Keyboard and sometimes they don't work on fresh start up, forcing me to unplug, and replug, the USB. Other times, I'll take a break, come back an hour later and they no longer work and I can't even unplug and replug the USBs. I have to close everything and restart. It's infuriating. I'm willing to spend money on a fix, if a newer powered hub circumvents these issues. It's clear Apple doesn't plan to address it anytime soon.

Had a chance to retry my Hyper Drive 11-in-1 hub (model GN30B) w/ a USB-A drive. Running Tahoe 26.2 I was able to connect to the drive.

The connection seemed a bit flaky but I can't be sure it was because a cable was moved possibly pulling on one of the ports. When I have an opportunity I'll check w/ other accessories.

Hi

I can't recognize USB hub with my Anker 563 USB C 10-in-1 HUB

MacBook Air (Retina, 13-inch, 2020) 1.1Ghz Intel i5

update to Sequoia 15.7.3

Also I can't access to that written https://www.siliconmotion.com/downloads

Which driver should be use on your driver downlad pages?

had the same with M4 pro after upgrade to 26.0.1. After trying every combination of reboots, power and connection went to 40cm cable solution. worked! Very annoying.

Same issue for me after updating to Tahoe. Using Amazon Basics Thunderbolt 4 dock.

Well, this turned out not to be a solution. The problem returned not much later.
