USB 3.0 Hub Broken on Mac OS Monterey 12.0.1

I have a M1 MacBook Air with an external Philips276C monitor with Power Delivery. Since update to Monterey, the screen works fine, but there is no power delivery. A senior apple advisor tolt me that the Philips needs a firmware update. Contacted Philips and they said that this isn't possible. Senior Advisor tolt me that this isn't a Apple problem....

I have a similar problem with a DELL K16A dock that used to work fine with my M1 MacBook Air with Big Sur.

After I updated to Monterey, the external display can't find the signal.

The dock has a HDMI, DisplayPort and a MiniDP and none of them work.

The USB-ports and power distribution do work.

I also have an Apple USB&HDMI dock and it work, but there is only one USB-A port in it.

I have a similar problem using a Philips display (346p1crh). Everything works except PD on my 16“ 2021 running 12.0.1. When i restart my MacBook, PD works. After plugging it out and in again PD stops working

I have a brand new 16in MacBook Pro M1Pro and my Apple usb keyboard via usb-c dongle works intermittently and I have some ports that don’t work at all

i am very close to returning my new laptop as I don’t want a$3000 computer that only

partially works

Same here, waited to upgrade to minimize risk for issues and didn't run into this thread until after I upgraded and my USB peripherals stopped working on my hub. Worked fine on previous OSX, broken immediately after Monterey. Macbook Air M1 Late 2020

Same thing happened to me, support was totally useless was passed from one person to another who tried different fixes… wasted precious time dealing with them instead of finishing a project that has a deadline .

I've just done the same. A Ugreen 6 in 1 USB-C Hub:

USB3.1 Hub:

  Product ID:	0x0626
  Vendor ID:	0x05e3  (Genesys Logic, Inc.)
  Version:	6.63
  Speed:	Up to 5 Gb/s

This is working fine for me, running a 1440p screen via HDMI, external keyboard and mouse, plus a Samsung T5.

I am having similar issue with my hub which I purchased from amazon. apple care guy does not even know about this bug and was telling me to reinstall OS. thankful I found this post and I am going to wait for next software release from apple to use my usb mouse.

really pathetic from apple knowing that this bug was detected in beta and still wasn't resolved.

Same issue on my Macbook Air M1

USB-C hub working fine until upgraded from Big Sur to Monterey now I cant sync with my iPhone or connect my USB-A external HDD for backups. A Kensington 32GB usb stick is somehow still working.

Please Apple - (un)fux it.

While my Logitech webcam now works (see my previous info on resetting the SMC), I have to kick start it by opening and shutting my MacBook! (I am using a large screen display connected by HDMI). Ridiculous.

I have had similar problems with my USB external hard drives since I upgraded. I literally have been an Apple consumer and even have my Mac 512K in my attic waiting for a future revival. There is absolutely no excuse for this to be happening, NONE. When you leave people with no alternatives even to use the most basic peripherals using USB in 2021 with no coherent fix in sight it is very disturbing and makes me question my own commitment to a brand I have been with for decades. Very disappointing.

Quick update: Not sure why, but i tested my MBP on a Anker USB-C Thunderbolt 3 dock, and it's able to not crash using two external monitors besides all the other USB items (Web Cam, ring light, external speakers).

When i use my Anker Apex USB-C Thunderbolt 4 dock (with 2 monitors and similar USB items) the MBP continues to lock up. I've been working on the Apex USB-C Thunderbolt 4 dock for the past few days with only one external monitor and it has not crashed. The issue is not brand specific, and for me seems to be related to the USB-C / Thunderbolt 4 hub conflicts with driving more than one external monitor.

Yep. They seem to have fixed recognition of USB-C devices after leaving sleep mode, at least for this situation. The second display works without any fiddling around, with or without an external drive on the hub.

No - absolutely helpful, I would love to have an entire website discussing cables and hubs from an "approved" viewpoint. In this fiasco, "approved" is bandied about a lot, without a definition of what that means or what it entails.

I deliberately bought 20gb usb-c cables (6 foot, maybe too long), and then usbc/usb3.x adapters (also saying 10-20gb) , in anticipation of the new Macbook Pro 2021. They don't work with usb3.x....

I have 3 usb hubs, but a couple are older, and they don't work (this is all with 12.1...)

So, if I had a "this will work, get it!" document, I'd be all over it... I do have some experimental hubs/cables coming this week, so I can hope, but any knowledge (from Apple would be nice, other than "buy Apple products) would be helpful.

The problem is that if say my cable is the wrong kind, why would I get the required speed in BigSur, same cable, same hub, its not working in Monterey. Funny thing is that after downgrading to BigSur everything works perfectly. It can't be hardware problem.

The problem here is not because I change my cable (or hardware) I use the same that I've been using. The only change I made was upgrade to Mac OS 12.01 then 12.1. If it was a hardware issue, the problem should exist in Mac OS 11.x too
