USB hub failing under Monterey

that's what brought me here.

Apple we need a quick fix

I'm now on 12.1 and still don't have anything working (re usb 3.0/3.1, and monitors).

I have hubs and shorter cables ordered from Amazon- will report back, hopefully with better results.

But at the moment, no love here for 12.1 (yet)

Hub problem still exists with 12.1 on M1 MBP and Hyper Drive. Connected devices either not seen, disappear or even set to read only; machine reboots during sleep mode. All worked fine prior to Monterey.

Also, notice that Disk Utility can take minutes to list devices, so something is, obviously, amiss!

I have also issues with the StarTech DKT30CSDHPD USB-C Hub. Devices connected to it get disconnected time to time, can be temporarily fixed by plugging it back in. Is it possible that the USB-C is not providing enough electricity and I need a hub with external power connection?

12.1 introduced the issue(s) for me. USB-C connected hubs, video via USB-C (i.e, my external monitor), are unrecognised now — they were working without any issue before the update, under 12.0.1. The monitor is a Dell U3219Q.

HDMI video now randomly flickers off and on often enough to be unusable. DisplayPort via a 3rd party adapter works, but a third party USB hub doesn't.

"Aukey Unity C71" usb-c hub on fresh install Monterey 12.1 on Macbook Pro m1 still does not work. I can use the HDMI port only. USB2 port does not work, ethernet port does not work either. USB3 ports work only under certain circumstances: a) I boot in safe mode, b) I only attach USB3 single compatible peripherals (not hubs). The machine is hardly usable.

I have this issue when connecting my 2021 iPad Pro to my brand new M1 Max Mac Book Pro running Monterey 12.1 using the Thunderbolt/USB-C ports. The iPad runs iPad OS 15.2. It rarely shows up in finder or system report thunderbolt or USB ports. Sometimes it does show up. Sometimes that's stable, sometimes not. Same behavior with my wife's 2021 iPad Pro, and with different Thunderbolt cables. As a control, connecting my iPhone 13 Pro via lightning-to thunderbolt cable works fine. Thunderbolt external drive also works fine except daisychaining does not work. External Thunderbolt hub connects fine. So in this case, there is a specific bug connecting the iPads to my M1 Max Mac Book Pro. Connecting via thunderbolt to an older Intel MacBook Pro running Big Sur worked, as did connecting via thunderbolt 3 to thunderbolt 2 adaptor to an even older Mac Book Pro.

For anyone who facing the issue external display not working as usual via usb-c after upgrade to Monterey, for my case...

• M1 max 16" macOS version 12.1
• Dell Display U3219Q

I've found WORKaround on Reddit : https://www.reddit.com/r/macsysadmin/comments/qgypzy/comment/hpjdnn9/?utm_source=share&utm_medium=web2x&context=3

Unfortunately this issue with USB hubs made me return my MacBook Air today. As others here said, this is not a small bug which one can work around, instead this is a fundamental problem which prevents many people from using MacBooks. I bought it for work and I can't connect mouse, keyboard and display to it.

My setup:

• MacBook Air M1, 16 GB
• Anker 5-in-1 usb hub (no power delivery)
• Monterey 12.1

Problem: Usb hub does not connect - power LED on the hub does not even come on.

I spoke to a Apple support today and I've been told to "wait for next release" - which is definitely not a solution for me given that I need this computer to work. I didn't have other choice except of returning mac - I can't easily revert back to 11.2, I can't keep buying more and more usb c hubs praying that one of them will eventually work.

Very disappointing. Bugs happen, but the fact there's no way to roll back make this situation much worse.

The take away here is that Apple is clearly not a serious company. This was well and good when hardly anyone used them for anything important, and they could claim "We do better because we focus on one set of hardware", but then Apple got big and never grew in two important ways:

1. Working with hardware that they didn't personally-overcharge you for
2. Critical features that Microsoft has had for decades, like rolling back broken updates.

But hey, the touchbar can run Doom, so it's worth it!

i have the same issues and im dissaspointed to see some have had it for months, updated and then my usb c hub stopped recognising ethernet, display works but ethernet has stopped, i tried reinstalling the driver but no luck !!

I actually can't quite believe Apple is shipping this s***. Broken USB? Is it 1995?

I am writing this to report the same issue, I am using M1 Macbook Air, my USB hub brands are QPNP and HyperDrive. After upgrading to Monterey, most ports are not working as expected. It can detect the microphone when attached to USB hub, however, it uses internal microphone instead of the external microphone, I can confirm this when I use the single USB adapter instead of the USB hub, it works with USB adapter with no issue. Please help fix this issue, thank you!

Same problem here, LG 32UN880-B not power delivery through the usb c cable. The whole point of having this monitor it was the "one cable" setup but now it goes on and off with the latest Monterey update (12.1).

Any solutions?

I can confirm that I just started experiencing this issue today, after a few weeks of it working fine. I didn't do any updates or anything, only restarted the computer.

• Computer: M1 Max MBP 16"
• Hub: OWC Thunderbolt 3 Dock
• Connected Devices:
  • 2 External Displays (are connected and work fine)
  • 3x USB 3.0 External Hard Drives (do not connect through the hub, but do when connected directly via dongle)
  • Hub is powering MBP through the single Thunderbolt 3 connection, per the usual

I finally pushed the button on 12.1, and it appears to have solved my USB issues. I'm just hoping I can avoid the memory leaks that I've heard about

Hi,

Just ran into this issue (of not having Power Delivery work)with an MacBook (M1Pro) in combination with a Philips 346P1 display. After some research I found that (for me) resetting the NVRAM works. After doing so power delivery works. However, it only works for as long as the USB C cable remains connected between the MacBook and the display. After unplugging I need to reset NVRAM again to get the functionality back.

Hope Apple comes with a real fix soon, seems to be way overdue.

Can't believe it, but looks like Monterey 12.2 fixed my USB-hub. Finally. Not sure about monitor, will test it, but USB 3.0 is working now. Yay!

My issue with the USB ports on my peripheral dock (UGREEN), which I engaged just today after upgrading to Monterey, has been resolved with the update to 12.2.

I'm happy to report the issue of connecting to USB devices through my OWC Thunderbolt 3 dock has also been resolved. However, it was not the upgrade to macOS 12.2 that did it. I updated the OS a few days prior without any change, then It started working properly after I shut my computer down (keeping the dock connected), and restarting. I did this several times over the past week but for whatever reason, it did the trick this time.

Regardless of the means, I am extremely happy this has FINALLY been resolved and I can use my hardware properly again!

I've updated to 12.2 and still have this issue. Apple, what's going on? How long do we have to wait for just regular fixes?

I am running macOS 12.1 Monterey and using Cadyce USB Hub (CA-CU3HG). Sometimes it works with Pendrive but it fails for an external USB camera and Microphone. Is there any solution apart from Downgrade?

Running 12.2 on a 2020 Intel MacBook Pro and the USB-Hub of my ThinkPad Thunderbolt 3 Dock (Gen 2) (PN: 40AN0135EU) is not working right now.

Funny enough: The two monitors connected to the Lenovo dock (one via DisplayPort, one via USB-C) are still working. But the USB ports of the USB-C monitor are also dead now. I plugged the USB-C Monitor into the MacBook directly and now the ports are working again. Devices connected to the Lenovo dock (like my webcam) are still dead.

Same problem on 2021 Macbook Pro 15' M1 chip: since Monterey, Aukey CB-C55 hub no longer makes external monitors work :(

I am using an external LG display connected to Macbook pro M1 2021 directly via USB-C. Before upgrading to Monterey it worked and after upgrading it stopped working. However, after upgrading to 12.2 it worked initially until first reboot but then stopped working again.

Extremely surprising to see these kind of issues tbh.
