USB 3.0 Hub Broken on Mac OS Monterey 12.0.1

I'm on 12.1 now and still no love with anything USB 3.0/3.1 - I have ordered more hubs and shorter cables from Amazon, so I have some hope that maybe my new Macbook Pro 2021 will work properly.

But at this moment - still dead in the water with USB 3 - and I don't think my new Mac would even work with Big Sur.

Perhaps you are aware of this already but it may bear repeating ...

USB 3 transfers require USB 3 approved cables. I once unwittingly used a USB 2.0 cable plugged into a USB 3.1 (Gen 2) hub capable of a maximum transfer rate of 10 Gbps. However, the USB 2.0 cable limited the transfer rate to a maximum of 480 Mbps. At first, I thought that the hub was defective until I replaced the USB 2.0 cable with a USB 3.0 one.

I have an M1 MacMini and have a J. Burrows 7 port USB 3.0 hub. Prior to the Monterey update everything was working like a dream! I had a webcam connected which would start up fine. After the update, when I open photobooth, the usb subsystem would become unresponsive. The system itself isn't using any CPU. When I unplug the hub from the back of the mac, and replug it in, i get control of the system again. It's almost as if the usb controllers are getting saturated with a flood of acks? Maybe there was a change in the way usb devices ack? However, heres' the kicker. If I plug in the webcam in the second USB, it works fine. Anyway, I'm unable to use my mic and webcam now, unless I plug it into my machine, but that's not a workable solution, because I've got a KVM too and share the webcam etc with 4 other machines. Apple please have a look at this, or tell us how to gather data and send it to you. Interestingly, when I switch apps from Photobooth to say, chrome for a few second, the webcam switches off. My expectation would've been that the webcam would stay on, regardless of which app i'm focused on?

My hub and peripherals work most of the time now. I occasionally have to restart, or plug power cord into hub so enough ports are available for webcam to go directly to macBook (not through hub). AND... the functions of the Alt and Cmd keys will oddly flip on me! Example of this headeache: the back one word versus whole line of text changes now and then! Before Monterey, I didn't have to think of thi. Now I do.

If the hubs works before update, the problem is definitely on the OS, simple like that

This problem persists in the 12.I pubIic b3ta. Just tried it with a fresh install on an external drive. Frustrating.

This problem is not confined to M1 Macs. I have the same problem on my 2019 MacBook Pro, which is Intel based. After installing Monterey, my plug in USB back up drives no longer connect. In addition, my LG monitor, purchased from Apple goes dark after using Luna to connect a 3rd screen. I power cycle the monitor and it comes up.

Just upgraded to Monterey 12.0.1. My ikling 15-1 hub stopped working. Power is there but data won't go through. I have a M1 MacBook Air. The external backup drive was not seen when connected using the hub. When I used the USB dongle that came with the MacBook Air it worked fine. Please fix!

Fortunately for me USB-C drives speed has turned good with Monterey but as I already said - with a bit of polemic - somebody somewhere in Cupertino is unable to develop good USB drivers as I'm seeing theese as the worst in the world since 1998.

This said, the USB worl is a mess itself. Many product are very low quality products rebranded and sold as per high quality products. This also for hubs, cables, cameras, keyboards, mice, ecc ecc. Therefore I'm asking myself if the problem is just into the dirvers.

Adding myself to the rant... I cannot run TM anymore, the disk external is not working anymore. the strange thing is that MacOS is asking the password for the disk, which I have provided. Then, nothing else happens. I believe this is also an issue with the higher level, as Disk Utilities get a spinning ball and cannot present the disks connected to the Mac... Something is wrong with the disk permissions, the disk mount, and the fact that an external disk is making a spinning ball of Disk Utility, while it was perfectly working with Big Sur, says enough... Never install version .0... never...

My Imc desk top works fine no problems not a M1 chips set. seams to be a problem with the M1 set up. this is what my I Mac desk top sees when I connect the hub. My Mac book pro laptop dose not see the lan hub at all.

I have spent all day trying to get the hub to work no luck the last thing apple support told me was to go back to Big Sur but on looking up how to do it you need A USB DRIVE but the hub that I use to do the usb drive is not working so how can I do what is needed to go back to Big Sur. you need to create a bootable installer on a thumb drive. is there any other way to do it? if not the Hub I bought about a month ago looks like it is no good on my Mac book pro works fine on my I Mac desk top running Monterey.still have a email to ikling but don't think they will get back to me till Monday. Will post if they can help or find a way to get the hub working.

One thing is sure: most accessories, today, are from strange brands which mostly don't meet the required quality standards especially as tecnologies move continuosly versus higher and higher performance and then standards' requirements. I recently had problems with Softraid's kext loading and looked a sw problem. Solved with a usb-c cable among 4. With the other 3, didn't work. All sold as per high quality usb-c cables.

So: where are the problems, sometimes...(?)

(In response to everybody...)

Nope. Electronics (as the human body, for example) are very complex systems. We cannot think with "simple" thoughts. Of course, I'm hoping for all you fellows in trouble that's a bug ans update will solve as changing the hardware is expensive. That said, I would have never have switched to a newly released OS version before reading about it around the web. Personally, i did it because I had enrolled the Public Beta program and found that PB 10 and 12.01 RC1 and 2 solved all my unsolvable problems in Big Sur (here is an M1 machine, BTW).

Good luck.
