USB 3.0 Hub Broken on Mac OS Monterey 12.0.1

I contacted TOTU, and they willingly refunded me (although they were confident it was not their problem... I'm surprised and grateful lol) I used that to buy an Anker 7-in-one (https://www.amazon.com/dp/B07PPGWQ15?psc=1&ref=ppx_yo2_dt_b_product_details) that was refurbed or something so that it was only about 30 dollars. It is far from ideal, but this hub works. I can also use a usb3.0 male to usbc female adapter to plug the TOTU hub into the Anker one and increase the USB ports that way (yes it's janky). Anyway, 12.1 is supposed to launch sometime later this month... we will have to see if they fix this issue by then.

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.

Further update: I have swapped out the cable to my Dell U3219Q display which was a USB 3.1 Gen2 cable for a Gen1 cable and the USB hub is now working at 5Gbps and devices (using the right cables) are also working as expected.

Looks like anything other than a USB-C 3.1 Gen1 cable just won't work properly.

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.

I have this problem with a Behringer UMC404HD audio interface not being recognized, and the "fix" (workaround) is strange: don't use external power on the interface.

When I plug in the interface without its external power plugged in, the interface is recognized by Monterey. If the interface is externally powered, it is not recognized.

I have this problem also on my Mac Mini M1 . External ASUS BluRay connected to one of the USB 3.1 ports which worked just fine on Big Sur won't read any disks. I decided to install the beta of Monterey but so far nothing.

What's strange is that the drive is there. It's listed and I can control it and see it in the system report but it just won't read and mount any disks,

as mentioned earlier in the thread I swapped the dell supplied USB-C 3.1 gen2 cable to a USB-C 3.1 gen1 cable yesterday afternoon and everything on the dell monitor was working again at 5gbps (where capable) - my 4k web cam was now working and drive transfers were back up to full speed.

But as of this morning I plugged the MacBook back in, after making no changes, and it is back at 480mbps if I use the port furthest away from me. If I use the other USB-C port then I don't see any USB devices at all.

Makes no sense. Have now reset SMC and reinstalled OS X after being on phone to apple support. No change. Will pick it up again with them this evening to see what they suggest.

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.

It's not fix, but this might be a go around until a 12.1 updated to fix the USB-C hubs is released. I'm using a MBP 2019. After wasting a weekend, i found a possible solution that doesn't make my system crash. The Monterey 12.01 made my Anker Apex basically a brick.

I randomly discovered if you are using an external USB hub that has a PD port, don't use the PD port to power your computer. When i used the hub with power it kept crashing my MBP. I then plugged the Apple wall wart directly into the MBP, then i'm using a unpowered USB-C hub (it has a PD port, but i'm not using it) for all my accessories (Web Cam, Keyboard, audio output). Also, i have an external monitor plugged directly into the MBP. I tried a second HDMI monitor plugged into hub, but it also crashed the machine. From what i can tell, you have to plug monitors directly into the computer's USB-C port, and if you want to use a hub don't use the PD port (Also, don't plug any monitor into the hub). My other USB 3.0 devices work fine in the unpowered hub.

This morning, my MBP crashed twice in 30 min when was using the PD port, but since i made the switch above it's done fine. It's just alot of wires all over my desk. Good Luck, Apple fix the issue

Issue: After Mac OS12 upgrade, some devices connected to USB-C hub ports not working. In my case, my Logitech mouse and keyboard worked, but my Logitech webcam did not. After considerable time, Apple support gave me the fix: 1. Turn off computer. 2. On left side of keyboard, press and hold Control & Option keys. 3. Still holding those 2 keys, on right side of keyboard to press Shift. 4. holding all three of those keys for 7 seconds, finally add holding down the Power key. 5. Hold down all four keys for another 7 seconds. 5. Release all keys, then press Power key. After computer reboots, my webcam worked again. I hope this works for you.

Docking station doesn't work for me either.

I have a CalDigit TS3 Plus Dock and am using it on a 2019 MBP 16" that is loaded. With Big Sur the dock worked a champ with an Anker USB powered hub connected to it that has multiple devices (Yeti microphone, webcam, hard drive for Time Machine, and a CAC reader) running, a display port cable connected to a monitor, a USB-C to HDMI cable connected to a monitor, and a 3.5mm audio jack that all ran great. ...until Monterey. Once I got that installed the computer would freeze, unfreeze and repeat the cycle. I had video issues as well, and sometimes the computer would shut down while it was frozen.

I changed cables, added and removed devices, updated the dock firmware and drivers for the computer with no success. I then took the monitors off of the dock and plugged them directly into the MBP. Well, that was the ticket as I no longer have the issues I was having. Monterey has broken the ability for my dock to handle video without throwing the MPB into a fit. So USB 3 is working just fine, as well as all the other connections that I can determine. It just pukes if video is attached.

I'm of the opinion that Apple blew it on this one and am probably going to reinstall Big Sur until this gets fixed. I'll be watching!

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.
