USB 3.0 Hub Broken on Mac OS Monterey 12.0.1

I also use this StarTech hub on my Mac mini (2018) running Monterey. Works well as far as I can tell.

With OS Monterey 12.1 that I've just installed the problem has not been resolved! (MacBook Pro 13 inch, M1, 2020)

NOT SOLVED!

Thanks, I am up-to-date and still having trouble. Appreciate the suggestion, though.

Same issue after upgrading MacBook Air M1 to Mac OS Monterey 12.0.1. USB 3.0 fails on two different multiport hubs (Choetech and MINIX). Works with a simple straight-thru USB-C<>USB-A converter.

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.

To check out the USB ports on the Xcellon, I hooked an external HDD to it (which was recognized). For whatever reason, with the external drive connected I no longer was losing video through the Xcellon display adapter. That was still with 12.0.1. Now to see if removing the HDD while under 12.1 lets the display stay active.

I'll add that many USB 3.0 or 3.1 cables that are sold as charging cables may also fail to support USB 3.0 & 3.1 data transfer speeds. Make sure your USB 3.0 or 3.1 cables are USB-IF certified for either gen1 (10Gbps) or gen2 (20Gbp).

Just FYI I have a Mac MIni M1 and use a TB hub with several drives (both Usb and TB) attached and an SD card always inserted and no connection issues running Monterey. Also had no issue with Big Sur.

Followup - it's been a busy day for me.

I have found Monterey 12.1 to be a great help. But there are still many misses - I think some are deliberate.

So - original title: USB 3.0 Hub Broken on Mac OS Monterey 12.0.1 - answer, yes, yes it is.

1. Update to Monterey 12.1 if you have these issues. A must do.
2. Don't trust your current hardware. Only because Apple may not.
3. I ordered a bunch of adapters/cables/hubs to test Apple. Mainly because I wanted to get this to work.
4. I found configurations that would work. I found configurations that did nothing from Apple's POV (which work with Big Sur).
5. For hubs, I found Anker and Sabrent to be almost always a "go". Didn't try any "Apple certified" solutions. There are certainly other brands that work well.
6. For hubs, many are NOT a go. Cheap knockoffs (which work with Big Sur) don't work in Monterey.
7. Cables/adapters - same scenario - some work, some don't. (I am aware of USB 3.x Gen X speed issues)

Bottom line - it appears that Apple is becoming "more strict" in allowing items to work - and we are in a process once again.

I now have a setup which seems aok, and quite a bit of "Apple does not approve anymore" items to return to Amazon (which I ABHOR doing, but necessary, I guess.)

NOTE: I did not test monitor access, though I do have one to test. One thing at a time.... ;)

Sorry if I'm duplicating information, but I'm having good success with StarTech hubs. I have a USB 3.0 and a USB 3.1 hub. Each is connected to a Mac mini (2018) USB 3.1 (Gen 2) Type C port. The USB 3.0 hub, itself, provides a Type C connector which is limited to 5 Gbps. The USB 3.1 hub ports are 10 Gbps (Type A connector).

Power distribution should be carefully considered. If I recall correctly, an external SSD would only function properly when connected to the Type C connector on the USB 3.0 hub. Also, be mindful of using the right USB cable (e.g. an older USB 2.0 cable limited the transfer rate to 480 Mbps).

I was forced to buy an M1 MacBook Air running Monterey because my 2017 MacBook Air had a catastrophic hardware failure. I was using a Logitech bluetooth mouse and keyboard with my old Mac, both of which have USB dongles. I bought an Anker hub and tried to use my Logitech keyboard with the Anker hub. My Mac failed to recognize the devices that used the dongles although I had no problem using my bluetooth printer. I thought the problem might be with the Anker hub so replaced it with the Belkin hub that was on the Apple web store (although no longer in stock -- had to buy elsewhere). The Apple technician I spoke with said her M1 Mac worked fine with that hub. Just opened it today, no luck. I've restarted, etc etc etc. Nothing. This is ridiculous...I was forced to spend $1000 to replace my 5-year-old Mac and now I can't use my mouse or external keyboard (both of which I need to sit at my desk and work). I'm beyond furious. Looks like I'm being forced to buy a new Apple keyboard and mouse since I can't make my old ones work at all. This is outrageous.

I also have an USB 3.0 hub that didn't stopped working after monterrey but now charges the devices soooooo slowwwww. Its horrible and I'm completly sure it's Monterrey fault

Upgraded to 12.1 and my usb c hub works (earlier it doesn’t work and had to downgrade to BigSur).

Looks promising. How many of you tried the new update?
